" running Fedora 16 (64-bit) on my Samsung laptop.
It's a dual boot machine (Windows 7 on a separate partition). The GRUB menu showed both operating systems, plus a "recovery" partition. This recovery partition is a Samsung thing, which allows me to back up, restore, and reinstall the OS (I had never used it before).
As I'm gathering my thoughts to install Fedora 17 (full install, not as an upgrade), I selected the "recovery" partition from the GRUB menu. It launched without problems, I intended to do a backup, but noticed that I didn't have my external drive available... so I exited the application (gracefully and without errors). The laptop did a reboot automatically and went to the GRUB menu as usual... but only for a fraction of a second (it didn't have enough time to display the list of options). It just flashes "GRUB" on the screen indefinitely.
Fortunately, I had made a new Fedora 17 Live CD (which I'm using to write this message) and managed to mount my original "home" directory and have just finished backing up my data to the external drive. Now I can experiment, since I've broken my laptop pretty good (all I can do is go into BIOS and boot from this Live CD).
Can I fix, restore, or reinstall GRUB (assuming that it's the problem)? Can anyone point me in the right direction?
As a last resort, I can do a full install of Fedora 17, hoping that the new installation restores GRUB functionality and that it detects the Windows 7 OS (I'm giving this laptop to my son for college... he'll need Windows).
