Cchroot to the mounted system, edit >/boot/grub/device.map, and re-install grub. I tried this. I replaced /dev/sdc by /dev/sda in devices.map on the USB-drive and made grub-install. It did not work. As a result, I can no longer boot from the built-in drive!!! This is a terrible desaster for me. The built-in drive contains my working F10 installation. I booted from a F10 Installation CD in rescue mode. The data is still present (under /mnt/sysimage). Can anyone please explain how can I make the built-drive bootable again?
