Relevant laptop is so old I don't know if it can boot from a physical USB device. I was suspecting that simplest thing would be copying suitable image to hard drive and let GRUB earn its keep ;}Indeed my trusty old Thinkpad X30 doesn't boot from USB keys (tho in theory it can boot from a USB floppy reader), so I use one of two alternative options: - Boot using the Grub on the X30's own HDD, and then ask Grub to boot the kernel+initrd found on the USB key (this is my favorite solution).
I think this is the path I should follow. It explicitly handles my immediate problem and most likely satisfactorily handles issue(s) on other machine(s).
Where would I find relevant GRUB documentation?
- Copy the USB key's kernel+initrd to the /boot partition on the X30's HDD and boot from that.
Can I copy the USB key's kernel+initrd to a currently empty partition and then treat it in manner similar to USB key above? [goal being not to mess with a currently functioning system ;]
- Take the HDD out of the X30 and connect it to my desktop via some
HDD<->USB adapter. Then do what I need to do to it from the comfort
of my desktop computer, typically using `chroot` along the way (this
is the second best).

Thank you.
