Gah. Any idea why the Windows installer isn't showing up as bootable?
We're using EFI. The installer image appears to be using a UDF filesystem.
@IceWolf how did you create the installer medium? I've never gotten it to work without the Microsoft installer creator thingy
@noiob Uh just dd.
@noiob We unfortunately don't /have/ a Microsoft installer creator thingy since we um don't have a working Windows installation! :P
@IceWolf this thing says to manually format the disk as FAT and copy over the files from the iso, I'd try that https://itsfoss.com/bootable-windows-usb-linux/
@IceWolf it's probably using a powershell cmdlet lol
@noiob ... wait your article's telling us to format it as ExFAT? /Huh/. I didn't know EFI firmware could just boot from ExFAT like that.
@IceWolf yeah it probably has to so it can boot from SD cards?
@noiob I kinda forgot SD cards used exFAT by default.
@IceWolf glad they do because it at least has some error correction
@IceWolf oh lol you can also just compress install.wim apparently https://www.dedoimedo.com/computers/windows-10-usb-media-linux.html
@noiob Oh neat!
And ooh wimtools /also/ has a command to properly split them, too!
@noiob Thanks!
Tried that already. Ran into issues with install.wim being too big for the filesystem per-file size limit. Tried splitting it up like https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/install-windows-from-a-usb-flash-drive says to... although apparently it's using a fancy command to do the splitting, which we don't have access to, which I bet that's why it didn't work.
