4. In Ventoy I had enabled Secure Boot and GPT. The only thing that changed is that the " No bootfile found for UEFI!" So I don't really see how that could be used to solve the specific problem we are being faced with here, because, however you plan to use UEFI:NTFS when Secure Boot is enabled, your target (be it Ventoy or something else) must be Secure Boot signed. It is designed to protect a system against malicious code being loaded and executed early in the boot process, before the operating system has been loaded. Some modern systems are not compatible with Windows 7 UEFI64 (may hang) Nevertheless, thanks for the explanation, it cleared up some things for me around the threat model of Secure Boot. Ventoy virtualizes the ISO as a cdrom device and boot it. I checked and they don't work. I don't remember exactly but it said something like it requires to install from an Installation media after the iso booted. Would MS sign boot code which can change memory/inject user files, write sectors, etc.? Insert a USB flash drive with at least 8 GB of storage capacity into your computer. Sign in So maybe Ventoy also need a shim as fedora/ubuntu does. Let the user access their computer (fat chance they're going to remove the heatsink and thermal paste to see if their CPU was changed, especially if, as far as they are concerned, no change as occurred and both the computer appearance and behaviour are indistinguishable from usual). The injection is just like that I extract the ubuntu.iso and change/add some script and create an new ISO file. Some Legacy BIOS has an access limitation and wont read a disk that exceeds the limitation. Can't install Windows 7 ISO, no install media found ? So it is pointless for Ventoy to only boot Secure EFI files once the user has 'whitelisted' it. Ventoy can detect GRUB inside ISO file, parse its configuration file and load its boot elements directly, with "linux" GRUB kernel loading command. Already on GitHub? On one of my Laptop Problem with HBCD_PE_x64.iso Uefi on start from Desktop error with Autoit v3: Pintool.exe Application error. How to suppress iso files under specific directory . I would assert that, when Secure Boot is enabled, every single time an unsigned bootloader is loaded, a warning message should be displayed. @chromer030 hello. The user could choose to run a Microsoft Windows Install ISO downloaded from the MS servers and Ventoy could inject a malicious file into it as it boots. @ventoy # Archlinux minimal Install with btrfs ## Introduction If you don't know about Arch Linux, and willing to learn, then check this post, - [Arch Linux](https://wiki .

In other words it will make their system behave as if Secure Boot is disabled, which they are unlikely to expect, else they would have disabled Secure Boot altogether to boot said media (which, if they control that system they can always easily do, especially if it's in a temporary fashion to boot a specific media that they know isn't Secure Boot compliant). preloader-for-ventoy-prerelease-1.0.40.zip, https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1401532, [issue]: Instead of dm-patch, consider a more secure and upstreamable solution that does not do kernel taint. The text was updated successfully, but these errors were encountered: I believe GRUB (at least v2.04 and previous versions if patched with Fedora patches) already work exactly as you've described. Which means that, if you have a TPM chip, then it certainly makes little sense to want to use its features with Secure Boot disabled. Where can I download MX21_February_x64.iso? @MFlisar Hiren's Boot CD was down with UEFI (legacy still has some problem), manjaro-kde-20.0-rc3-200422-linux56.iso BOOT Well, that's pretty much exactly what I suggested in points 1-4 from the original post, with point 4 altered from "an error should be returned to the user and bootx64.efi should not be launched" to "an error should be returned to the user who can then decide if they still want to launch bootx64.efi". Ventoy About File Checksum 1. I would also like to point out that I reported the issue as a general remark to help with Ventoy development, after looking at the manner in which Ventoy was addressing the Secure Boot problem (and finding an issue there), rather than as an actual Ventoy user. I have a solution for this. The MEMZ virus nyan cat as an image file produces a very weird result, It also happens when running Ventoy in QEMU, The MEMZ virus nyan cat as an image file produces a very weird result No boot file found for UEFI (Arch installation) - reddit However, Ventoy can be affected by anti-virus software and protection programs. I can provide an option in ventoy.json for user who want to bypass secure boot. Users enabled Secure Boot to be warned if a boot loader fails Secure Boot validation, regardless of where that bootloader is executed from. () no boot file found for uefi. On the other hand, I'm pretty sure that, if you have a Secure Boot capable system, then firmware manufacturers might add a condition that you can only use TPM-based encryption if you also have Secure Boot enabled, as this can help reduce attack vectors against the TPM (by preventing execution of arbitrary code at the early UEFI boot stage, which may make poking around the TPM easier if it has a vulnerability). @adrian15, could you tell us your progress on this? To create a USB stick that is compatible with USB 3.0 using the native boot experience of the Windows 10 Technical Preview media (or Windows 8/Windows 8.1), use DiskPart to format the USB stick and set the partition to active, then copy all of the files from inside the ISO . They do not provide a legacy boot option if there is a fat partition with an /EFI folder on it. Ventoy Forums ", same error during creating windows 7 Maybe the image does not support X64 UEFI." UEFI64 Bootfile \EFI\Boot\bootx64.efi is present. Option 2: bypass secure boot If you did the above as described, exactly, then you now have a good Ventoy install of latest version, but /dev/sdX1 will be type exFAT and we want to change that to ext4, so start gparted, find that partition (make sure it is unmounted via right click in gparted), format it to ext4 and make sure to . The boot.wim mode appears to be over 500MB. Maybe because of partition type XP predated thumbdrives big enough to hold a whole CD image, and indeed widespread use of USB thumb drives in general. Thanks. No bootfile found for UEFI, maybe the image doesnt support ia32 uefi This means current is MIPS64EL UEFI mode. For Hiren's BootCD HBCD_PE_x64.iso has been tested in UEFI mode. 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. That error i have also with WinPE 10 Sergei is booting with that error ( on Skylake Processor). And they can boot well when secure boot is enabled, because they use bootmgr.efi directly from Windows iso. Yet, that is technically what Ventoy does if you enrol it for Secure Boot, as it makes it look like any bootloader, that wasn't signed by Microsoft, was signed by Microsoft. The fact that it's also able to check if a signed USB installer wasn't tampered with is just a nice bonus. DiskGenius @adrian15, could you tell us your progress on this? Any progress towards proper secure boot support without using mokmanager? You can't just convert things to an ISO and expect them to be bootable! Is it possible to make a UEFI bootable arch USB? Already have an account? 1.0.84 BIOS www.ventoy.net ===> Now there's no need to format the disk again and again or to extract anything-- with Ventoy simply copy the ISO file to the USB drive and boot it. I remember that @adrian15 tried to create a sets of fully trusted chainload chains I have this same problem. Oh and obviously, once that is done, Ventoy will need to make sure that it's not possible to run an older versions of it, in a Secure Boot environment where a newer version has been enrolled, as it would still defeat the whole thing. Users may run into issues with Ventoy not working because of corrupt ISO files, which will create problems when booting an image file. Code that is subject to such a license that has already been signed might have that signature revoked. By the way, this issue could be closed, couldn't it? Yes, I finally managed to get UEFI:NTFS Secure Boot signed 2 days ago, and that's part of why there's a new release of Rufus today, that includes the signed version of UEFI:NTFS.

Happy to be proven wrong, I learned quite a bit from your messages. This could be useful for data recovery, OS re-installation, or just for booting from USB without thinking about additional steps. It's a pain in the ass to do yes, but I wouldn't qualify it as very hard. Would be nice if this could be supported in the future as well. Sign in An encoding issue, perhaps (for the text)? I was able to create a Rufus image using "GPT for UEFI" and the latest Windows ISO (1709 updated in 12/2017). All of these security things are there to mitigate risks. It's the job of Ventoy's custom GRUB to ensure that what is being chainloaded is Secure Boot compliant because that's what users will expect from a trustworthy boot application in a Secure Boot environment. Will there be any? Just create a FAT32 partition, change its label to ARCH_YYYYMM (fill in the ISO's date, now it would be ARCH_202109) and extract the Arch ISO to it. 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). Users have been encountering issues with Ventoy not working or experiencing booting issues. 3. and leave it up to the user.

Format Ext4 in Linux: sudo mkfs -t ext4 /dev/sdb1 As Ventoy itself is not signed with Microsoft key, it uses Shim from Fedora (or, more precisely, from Super UEFIinSecureBoot Disk). 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. Rik. debes activar modo uefi en el bios When you run into problem when booting an image file, please make sure that the file is not corrupted.

JonnyTech's response seems the likely circumstance - however: I've I've hacked-up PreLoader once again and managed to cleanly chainload Ubuntu ISO with Secure Boot enabled. Maybe the image does not support X64 UEFI" hello everyone Using ventoy, if I try to install the ISO. 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. Ventoy is able to chain boot Windows 10 (build 2004) just fine on the same systems. Heck, in the absolute, if you have the means (And please note here that I'm not saying that any regular Joe, who doesn't already have access to the whole gammut of NSA resources, can do it), you can replace the CPU with your own custom FPGA, and it's pretty much game over, as, apart from easy to defeat matters such as serial number check, your TPM will be designed to work with anything that remotely looks like a CPU, and if you communicate with it like a CPU would, it'll happily help you access whatever data you request such as decrypted disk content. About Secure Boot in UEFI mode - Ventoy MD5: f424a52153e6e5ed4c0d44235cf545d5 If you get some error screen instead of the above blue screen (for example, Linpus lite xxxx). Can't try again since I upgraded it using another method. ISO file name (full exact name) Of course, there are ways to enable proper validation. Especially, UEFI:NTFS is not a SHIM, and I don't maintain a set of signatures that I allow binaries signed with through. That is just to make sure it has really written the whole Ventoy install onto the usb stick. If your PC is unable to process Ventoy as bootable media, then you may need to disable secure boot. Ventoy 1.0.55 is available already for download. The iso image (prior to modification) works perfectly, and boots using Ventoy. I have used OSFMount to convert the img file of memtest v8 to iso but I have encountered the same issue. If that was the case, I would most likely sign Ventoy for my SHIM (provided it doesn't let through unsigned bootloaders when Secure Boot is enabled, which is the precise issue we are trying to solve) since, even if it's supposed to be a competitor of Rufus, I think it's a very nice solution and I'm always more than happy to direct people who would like to have a multiboot version of Rufus to use Ventoy instead. New version of Rescuezilla (2.4) not working properly.

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. How to Install Windows 11 to Old PC without UEFI and TPM 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).

Add firmware packages to the firmware directory. Legacy? Is there a way to force Ventoy to boot in Legacy mode? I have installed Ventoy on my USB and I have added some ISO's files : 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. gsrd90 New Member. then there is no point in implementing a USB-based Secure Boot loader. All the userspace applications don't need to be signed. Ventoy is open-source software that allows users to create ISO, WIM, IMG, VHS(x), and EFI files onto a bootable USB drive. The idea that Ventoy users "should know what they are getting into" or that "it's pointless to check UEFI bootloaders for Secure Boot" once Ventoy has been enrolled is disingenuous at best. @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.

I'd be interested in a shim for Rufus as well, since I have the same issue with wanting UEFI:NTFS signed for Secure Boot, but using GRUB 2 code for the driver, that makes Secure Boot signing it impossible. There are many kinds of WinPE. That's actually the whole reason shims exist, because Microsoft forbade Linux people to get their most common UEFI boot manager signed for Secure Boot, so the Linux community was forced into creating a separate non GPLv3 boot loader that loads GRUB, and that can be signed for Secure Boot. cambiar contrasea router nucom; personajes que lucharon por la igualdad de gnero; playa de arena rosa en bahamas; 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?

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). 1.- comprobar que la imagen que tienes sea de 64 bits 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. I can guarantee you that if you explain the current situation to the vast majority of Ventoy users who enrolled it in a Secure Boot environment, they will tell you that this is not what they expected at all and that what they want, once enrolled, is for Ventoy to only let through UEFI boot loaders that can be validated for Secure Boot and produce the expected Secure Boot warning for the ones that don't. For more information on how to download and install Ventoy on Windows 10/11, we have a guide for that. This option is enabled by default since 1.0.76. 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. the main point of Secure Boot is to allow TPM to validate the running system before releasing stored keys, isn't it?
