Hi,
I was wondering if it was possible to boot the existing F40 installation
from a USB. I tried to research this but everything I was able to find
dealt with booting a live image of F40 from USB and/or installing a live
image of F40 on a USB.
What I want is to create a USB stick with /boot and /boot/efi fs in such
a way that it boots an existing F40 installation on a HD.
I am not talking about rescuing the system from a live Fedora USB. I am
talking about a fully automatic boot of an existing installed Fedora
from a USB.
Is it possible and what would it involve?
Check out ventoy. It boots to a menu containing links to ISOs. Make a
selection and it boots into that ISO. Great way to explore different
distros.
It has 2 partitions:
part1 is all of the usb minus 32MB and contains your ISOs
part2 is 32MB and contains all the boot stuff and boots many o/s's
here is part2's layout ( I've skipped listing the .mod files )
