Windows 11 24H2 iso failing to install, error

[NovaViper]

Whenever I try to load the Win11_24H2_English_x64.iso, I get this 0x8007001 0x4002f. I have the filesystem as exfat with secure boot off so im not sure why it's not letting me install. The error occurs right after agreeing to the terms of the OS. Im using MultiOS on NixOS with sudo nix run github:Mexit/MultiOS-USB -- /dev/sdb -f exfat

Nix-info

❯ nix-info -m

I get this 0x8007001 0x4002f

It means that the Windows installer cannot access the installation files. Which is correct because the installer only recognises fat32 and ntfs. The iso must reside on one of those filesystems.

@JonnyTech I thought it can boot on exfat? I've had a ventoy install and it was configured with exfat too and works fine with Linux and Windows

[JonnyTech]

If you boot the computer in BIOS / MBR mode then exfat works, but booting in UEFI / GPT mode fails with the error message. Maybe ventoy creates a MBR based drive?

Maybe try this suggestion from a ventoy issue (https://github.com/ventoy/Ventoy/issues/2769#issuecomment-2254243036):

select Previous Version of Setup during the windows setup

🤔 Ya know actually it was using MBR. Also I did manage to get Windows 11 (this time, it was 25H2) to boot with MultiOS-USB with exfat

Well done. Please share your process so that other windows users can benefit.

I didn't do anything different other than imaging it on a different computer with -f exfat, and redownloaded the Windows ISO

Ah problem now is none of the Linux installers (Linux mint, NixOS, FreeNAS Scale).. only nonWindows thing I got to boot was shredos

Edit: Actually I got clonezilla to boot too
