3. https://nyancat.fandom.com/wiki/MEMZ_Nyan_Cat It's what Secure Boot is designed to do on account of being a trust chain mechanism that, when enabled, MUST alert if trust is broken. For example, Ventoy can be modified to somehow chainload full chain of distros shim grub kernel, or custom validation functions could be made, which would, for example, validate and accept files signed with certificates in DB + a set of custom certificates (like ones embedded in distros' Shims), or even validate and automatically extract Shims embedded certificates and override EFI validation functions (as it's done currently to completely disable validation), but is this kind of complexity worth it for a USB boot utility which is implemented to be simple and convenient? Any ideas? You can open the ISO in 7zip and look for yourself. On the other hand, the expectation is that most users would only get the warning very occasionally, and you definitely want to bring to their attention that they might want to be careful about the current bootloader they are trying to boot, in case they haven't paid that much attention to where they got their image @ventoy, @pbatard, any comments on my solution? It's a pain in the ass to do yes, but I wouldn't qualify it as very hard. Sign in if this issue was addressed), it could probably be Secure Boot signed, in the same manner as UEFI:NTFS was itself Secure Boot signed. Especially, UEFI:NTFS is not a SHIM, and I don't maintain a set of signatures that I allow binaries signed with through. Yeah, I think UEFI LoadImage()/StarImage(), which is what you'd call to chain load the UEFI bootloader, are set to validate the loaded image for Secure Boot and not launch it for unsigned/broken images, if Secure Boot is enabled (but I admit I haven't formally validated that). And of course, by the same logic, anything unsigned should not boot when Secure Boot is active. And, unless you're going to stand behind every single Ventoy user to explain why you think it shouldn't matter that Ventoy will let any unsigned bootloader through, that's just not going to fly. If Secure Boot is not enabled, proceed as normal. In this situation, with current Ventoy architecture, nothing will boot (even Fedora ISO), because the validation (and loading) files signed with Shim certificate requires support from the bootloader and every chainloaded .efi file (it uses custom protocol, regular EFI functions can't be used. There are also third-party tools that can be used to check faulty or fake USB sticks. @pbatard Sorry, I should have explained my position clearer - I fully agree that the Secure Boot bypass Ventoy uses is not secure, and I'm not using Ventoy exactly because of it. Open File Explorer and head to the directory where you keep your boot images. When Secure Boot is enabled, BIOS boot (CSM) should not work at all, since it would completely defeat the purpose of only allowing signed executables to boot.

There are many suggestion to use tools which make an ISO bootable with UEFI on a flash disk, however it's not that easy as you can only do that with UEFI-enabled ISO's. By UEFI enabled ISO's I mean that the ISO files contain a BOOT\EFI directory with a EFI bootloader. The USB partition shows very slow after install Ventoy.

My guesd is it does not. a media that was created without using Ventoy) running in a Secure Boot environment, so if your point is that because Ventoy uses a means to inject content that Microsoft has chosen not to secure, it makes the whole point of checking Secure Boot useless, then that reasoning logically also applies to official unmodified retail Windows ISOs, because you might as well tell everyone who created a Windows installation media (using the MCT for instance): "There's really no point in having Secure Boot enabled on your system, since someone can just create a Windows media with a malicious Windows\System32\winpeshl.exe payload to compromise your system at early boottime anyway" Again, if someone has Secure Boot enabled, and did not whitelist a third party UEFI bootloader themselves, then they will expect the system to warn them in that third party bootloader fails Secure Boot validation, regardless of whether they did enrol a bootloader that chain loaded that third party bootloader.

Does the iso boot from s VM as a virtual DVD? privacy statement. mishab_mizzunet 1 yr. ago When it asks Delete the key (s), select Yes. So, I'm trying to install Arch, but after selecting Arch from Ventoy I keep getting told that "No Bootfile found for UEFI! MD5: f424a52153e6e5ed4c0d44235cf545d5 Legacy? Customizing installed software before installing LM. About Fuzzy Screen When Booting Window/WinPE, Ventoy2Disk.exe can't enumerate my USB device. You can reformat it with FAT32/NTFS/UDF/XFS/Ext2/Ext3/Ext4 filesystem, the only request is that Cluster Size must greater than or equal to 2048. Format XFS in Linux: sudo mkfs -t xfs /dev/sdb1, It may be related to the motherboard USB 2.0/3.0 port. Not associated with Microsoft. 2.-verificar que la arquitectura de la imagen iso sea compatible con el procesador, 1.-modo uefi: However what currently happens is that people who do have Secure Boot enabled will currently not be alerted to these at all. That doesn't mean that it cannot validate the booloaders that are being chainloaded. For secure boot please refer Secure Boot . Using Ventoy-1.0.08, ubuntudde-20.04-amd64-desktop.iso is still unable to boot under uefi. Ventoy is an open source tool that lets you create a bootable USB drive for ISO files. they reviewed all the source code). There are two bugs in Ventoy: Unsigned bootloader Linux ISOs or ISOs without UEFI support does not boot with Secure Boot enabled. ", same error during creating windows 7 But of course, it's your choice to pick what you think is best for your users and the above is just one opinion on the matter. @ventoy Will there be any? 1.0.84 MIPS www.ventoy.net ===> Else I would have disabled Secure Boot altogether, since the end result it the same. Thanks a lot. There are many kinds of WinPE. Maybe I can provide 2 options for the user in the install program or by plugin. i was test in VMWare 16 for rufus, winsetupusb, yumiits okay, https://drive.google.com/file/d/1_mYChRFanLEdyttDvT-cn6zH0o6KX7Th/view?usp=sharing. cambiar contrasea router nucom; personajes que lucharon por la igualdad de gnero; playa de arena rosa en bahamas; So all Ventoy's behavior doesn't change the secure boot policy. Thank you for your suggestions! I didn't add an efi boot file - it already existed; I only referenced So any method that allows users to boot their media without having to explicitly disable Secure Boot can be seen as a nice thing to have even if it comes at the price of reducing the overall security of one's computer. To add Ventoy to Easy2Boot v2, download the latest version of Ventoy Windows .ZIP file and drag-and-drop the Ventoy zip file onto the \e2b\Update agFM\Add_Ventoy.cmd file on the 2nd agFM partition. Have a question about this project? when the user Secure Boots via MokManager - even when booting signed efi files of Ubuntu or Windows? We talk about secure boot, not secure system. Secure Boot is tricky to deal with and can (rightfully) be seen as a major inconvenience instead of yet another usually desireable line of defence against malware (but by all means not a panacea). When enrolling Ventoy, they do not. @ventoy Sign up for a free GitHub account to open an issue and contact its maintainers and the community. I am just resuming my work on it. Just some of my thoughts: I've already disabled secure boot. The main point of Secure Boot is to prevent (or at least warn about) the execution of bootloaders that have not been vetted by Microsoft or one of the third parties that Microsoft signed a shim for (such as Red Hat). Many thanks! @ValdikSS, I'm not seeing much being debated, when the link you point to appears to indicate that pretty much everybody is in agreement that loading unsigned kernels from GRUB, in a Secure Boot environment, is a bug (hence why it was reported as such). Fix them with this tool: If the advices above haven't solved your issue, your PC may experience deeper Windows problems. Most of modern computers come with Secure Boot enabled by default, which is a requirement for Windows 10 certification process. I used Rufus on a new USB with the same iso image, and when I booted to it with UEFI it booted successfully. Hi, thanks for your repley boot i have same error after menu to start hdclone he's go back to the menu with a black windows saying he's loading the iso file to mem and that it freez. So, Ventoy can also adopt that driver and support secure boot officially. The point of this issue is that people are under the impression that because Ventoy supports Secure Boot, they will get the same level of "security" booting Secure Boot compliant media through Ventoy as if they had booted that same media directly, which is indeed a fair expectation to have, since the whole point of boot media creation software is to have the converted media behave as close as possible as the original would. JonnyTech's response seems the likely circumstance - however: I've Follow the urls bellow to clone the git repository. Therefore, Ventoy/Grub should be altered as follows: Hopefully this shouldn't be too complex to add, though it may require some research, and modifying GRUB to do just that might require a lot of work. I am not using a grub external menu. 5. extservice Fedora/Ubuntu/xxx). Menu Option-->Secure Boot Support for Ventoy2Disk.exe and -s option for Ventoy2Disk.sh Ventoy does support Windows 10 and 11 and users can bypass the Windows 11 hardware check when installing. Yeah to clarify, my problem is a little different and i should've made that more clear. @ventoy I can confirm this, using the exact same iso. But unless it exploits a Secure Boot vulnerability or limitation (or you get cozy with the folks controlling shim keys), that bootloader should require to be enrolled to pass Secure Boot validation, in the same manner as Ventoy does it. can u fix now ? I thought that Secure Boot chain of trust is reused for TPM key sealing, but thinking about it more, that wouldn't really work. However, some ISO files dont support UEFI mode so booting those files in UEFI will not work. Maybe because of partition type And that is the right thing to do. memz.mp4. Questions about Grub, UEFI,the liveCD and the installer. KANOTIX uses a hybrid ISO layout, it definitely has X64 UEFI in ISO9660 and FAT12 (usually 1MiB offset). It should be specially noted that, no matter USB drive or local disk, all the data will be lost after install Ventoy, please be very careful. . So use ctrl+w before selecting the ISO. Tested Distros (Updating) I don't have a IA32 hardware device, so I normally test it in VMware. Please refer: About Fuzzy Screen When Booting Window/WinPE. This is also known as file-rolller. Tried with archlinux-2021.05.01-x86_64 which is listed as compatible and it is working flawlessly. Ventoy loads Linux kernels directly, which are also signed with embedded Shim certificate (not with the certificate trusted by EFI DB). 1.0.84 AA64 www.ventoy.net ===> Thus, being able to check that an installer or boot loader wasn't tampered with is not a "nice bonus" but is something that must be enforced always in a Secure Boot enabled environment, regardless of the type of media you are booting from, because Secure Boot is very much designed to help users ensure that, when they install an OS, and provided that OS has a chain of trust that extends all the way, any alteration of any of the binary code that the OS executes, be it as part of the installation or when the OS is running, will be detected and reported to the user and prevent the altered binary code to run. It was actually quite the struggle to get to that stage (expensive too!) Last time I tried that usb flash was nearly full, maybe thats why I couldnt do it. The boot.wim mode appears to be over 500MB. I've made some tests this evening, it should be possible to make more-or-less proper Secure Boot support in Ventoy, but that would require modification of grub code to use shim protocol, and digital signatures for all Ventoy efi files, modules, etc. Option 1: Completly by pass the secure boot like the current release. The fact that it's also able to check if a signed USB installer wasn't tampered with is just a nice bonus. ? access with key cards) making sure that your safe does get installed there, so that it should give you an extra chance to detect ill intentioned people trying to access its content. Ventoy virtualizes the ISO as a cdrom device and boot it. Currently when boot the ISO file failed as a Virtual CDROM, Ventoy will try to parse the grub configuration file inside the ISO file and try to boot it direclty with. If so, please include aflag to stop this check from happening! ***> wrote: What's going on here? You can put a file with name .ventoyignore in the specific directory. I don't remember if the shortcut is ctrl i or ctrl r for grub mode. The current release of Slax (slax-64bit-11.2.1.iso) fails to boot using UEFI64 using ventoy with the error message: The BIOS decides to boot Ventoy in Legacy BIOS mode or in UEFI mode. Freebsd has some linux compatibility and also has proprietary nvidia drivers. If that is not the case already, I would also strongly urge everyone to consider the problem not as "People who want Secure Boot should perform extra steps to ensure that only signed executable will boot" but instead as "People who don't care about Secure Boot but have it enabled should either disable Secure Boot or perform extra steps if they want unsigned executables to boot". then there is no point in implementing a USB-based Secure Boot loader. Hi, Hiren's Boot CD can be booted by Ventoy in Memdisk mode, you try Ventoy 1.0.08 beta2. If a user is booting a lot of unsigned bootloaders with Secure Boot enabled, they clearly should disable Secure Boot in their settings, because, for what they are doing, it is pretty much pointless. Remove Ventoy secure boot key. For instance, if you produce digitally signed software for Windows, to ensure that your users can validate that when they run an application, they can tell with certainty whether it comes from you or not, you really don't want someone to install software on the user computer that will suddenly make applications that weren't signed by you look as if they were signed by you. Now, that one can currently break the trust chain somewhere down the line, by inserting a malicious program at the first level where the trust stops being validated, which, incidentally, as a method (since I am NOT calling Ventoy malicious here) is very similar to what Ventoy is doing for Windows boot, is irrelevant to the matter, because one can very much conceive an OS that is being secured all the way (and, once again, if Microsoft were to start doing just that, then that would most likely mark the end of being able to use Ventoy with Windows ISOs since it would no longer be able to inject an executable that isn't signed by Microsoft as part of the boot process) and that validates the signature of every single binary it runs along the way which means that the trust chain needs to start somewhere and (as far as user providable binaries are concerned) that trust chain starts with Secure Boot. 5. The main annoyance in my view is that it requires 2 points of contact for security updates (per https://github.com/rhboot/shim-review) and that I have some doubts that Microsoft will allow anything but a formal organization with more than a couple of people to become a SHIM provider. Hi, HDClone can be booted by Ventoy in Memdisk mode for legacy BIOS, you try Ventoy 1.0.08 beta2. lo importante es conocer las diferencias entre uefi y bios y tambien entre gpt y mbr. openSUSE-Tumbleweed-XFCE-Live-x86_64-Snapshot20200402-Media - 925 MB, star-kirk-2.1.0-xfce-amd64-live.iso - 518 MB, Porteus-CINNAMON-v5.0rc1-x86_64.iso - 300 MB In Windows, some processes will occupy the USB drive, and Ventoy2Disk.exe cannot obtain the control right of the USB drive, so that the device cannot be listed. Anything Debian-based fails to boot for me across two computers and several versions of Ventoy. Mybe the image does not support X64 UEFI! Have a question about this project? @BxOxSxS Please test these ISO files in Virtual Machine (e.g. That would be my preference, because someone who wants to bypass Secure Boot indiscriminately, without disabling Secure Boot altogether, should have a clue what they are doing, and the problem with presenting options as a dialog is that you end up with tutorials that advise users to pick the less secure option, because whoever wrote happened to find the other choices inconvenient without giving much thought about the end result. Ventoy should only allow the execution of Secure Boot signed executables when Secure Boot is enabled, Microsoft's official Secure Boot signing requirements. its okay. I see your point, this CorePlus ISO is indeed missing that EFI file. No bootfile found for UEFI, maybe the image doesnt support ia32 uefi error, asus t100ta Kinda solved: Cant install arch, but can install linux mint 64 bit. In a fit of desperation, I tried another USB drive - this one 64GB instead of 8GB. Can it boot ok? If the ISO file name is too long to displayed completely. 2. for the suggestions. I tested live GeckoLinux STATIC Plasma 152 (based on openSUSE) with ventoy-1.0.15. @shasheene of Rescuezilla knows about the problem and they are investigating. But that not means they trust all the distros booted by Ventoy. Already on GitHub? Linux distributives use Shim loader, each distro with it's own embedded certificate unique for each distro. If you really want to mount it, you can use the experimental option VTOY_LINUX_REMOUNT in Global Control Plugin. @pbatard, if that's what what your concern, that could be easily fixed by deleting grubia32.efi and grubx64.efi in /EFI/BOOT, and renaming grubia32_real.efi grubia32.efi, grubx64_real.efi grubx64.efi. Thank you both for your replies. Windows 7 32-bit does not support UEFI32 - you must use Win7 64-bit.. You may need to disable Secure Boot in your BIOS settings first (or convert the ISO to a .imgPTN23 file using the MPI Tool Kit). , Laptop based platform: Already on GitHub? I downloaded filename Win10_21H2_BrazilianPortuguese_x64.iso It seems the original USB drive was bad after all. pentoo-full-amd64-hardened-2020.0_p20200527.iso - 4 GB, avg_arl_cdi_all_120_160420a12074.iso - 178 MB, Fedora-Security-Live-x86_64-Rawhide-20200419.n.0.iso - 1.80 GB Shims and other Secure Boot signed chain loaders do not remove the feature of warning about boot loaders that have not been signed (by either MS or the Shim holders). UEFi64? 1.0.84 IA32 www.ventoy.net ===> In this case, only these distros that bootx64.efi was signed with MS's key can be booted.(e.g. https://osdn.net/projects/manjaro/storage/kde/, manjaro-kde-20.0-rc3-200422-linux56.iso BOOT PS: It works fine with original ventoy release (use UEFIinSecureBoot) when Secure boot is enabled. 04-23-2021 02:00 PM. But, currently, that is not the case at all, which means that, independently of the merits of Secure Boot for this or that type of media (which is a completely different debate altogether), there is a breach of the security contract that the user expects to see enforced and therefore something that needs to be addressed. but CorePure64-13.1.iso does not as it does not contain any EFI boot files. I was able to create a Rufus image using "GPT for UEFI" and the latest Windows ISO (1709 updated in 12/2017).
