I am trying to boot to an USB stick from Grub, and I have found a few sites that explain how to do it, but when I follow those instructions it does not seem to work. I think those guides may simply be outdated. I did find https://askubuntu.com/a/436735, but that one seems to cover only how to add an entry to grub when it already has a working system running on it.
https://blog.viktorpetersson.com/2014/07/29/how-to-boot-from-usb-with-grub2.html tells me to run the following from the grub shell:
grub> linux (hd1,msdos1)/install/vmlinuz root=/dev/sdb1 grub> initrd (hd1,msdos1)/install/initrd.gz grub> boot
But the stick only contains /efi/boot/bootx64.efi and /efi/boot/grubx64.efi. I found this by setting
set root=(hd1,msdos2) (which is the usb stick) and then tabbing through on
find /. So my question is: how can I make grub boot from this USB stick?
PS: on this computer, booting to usb from the BIOS does not seem to work.
