While installing Fedora 42 on a small Lenovo computer with a new/empty 1TB SSD. It seems to include the USB flash when installing grub.
First image is what I selected and the second image is after setup completes successfully and I reboot without the flash drive. Flash drive also boots to a broken grub menu when trying to use it again. I re-image the flash drive and we’re back to the first image.
Yep, just tried the settings below on another machine. For some reason the machine doesn’t even want to boot from the drive this way, but I’m starting to get suspicious of my flash drive.
I’ve also tried Rufus and Ventoy. I’m going to try Fedora 41 and see if I can get a different flash drive for this.
Fedora 41 booted from Ventoy on a different usb did not overwrite the /boot of the drive, which is nice, but still doesn’t boot correctly. This seems to be something to do with the machine’s bios doing strange things with UEFI.
Supposedly it needs a UEFI entry for windows. I have tried following the instructions here and it still doesn’t seem to work. I did get the machine to boot by leaving the Ventoy drive in and selecting the SSD in the BIOS, but I really don’t want to operate this way.
