http://forums.fedoraforum.org – I have my FC11 system set up to automatically download and install updates. I had to reboot yesterday because of one of these updates. It seems that this update messed up grub. When I rebooted I only got the flickering cursor. So far I have tried the following using the rescue disk and executing chroot /mnt/sysimage fdisk -l gives me this result : I have /dev/sda, /dev/sdb, /dev/sdc Boot flag is with /dev/sda1 which also has FIlesystem Linux, where the other I notice have filesystem Linux LVM (don't know if that is relevant). I tried to restore grub. grub > find /grub/grub.conf hd(0,0) > root (hd0,0) Filesystem type is ext2fs partition type 0x83 > setup (hd0) and there were no error messages. However, no change when rebooting. The device map says that hd0 = /dev/sda hd1= /dev/sdb hd2= /dev/sdc I also did a grub-install --recheck /dev/sda All to no avail. The following struck me as strange, but not sure how relevant : - In grub, "find /boot/grub/grub.conf" gave me "file not found"; however, with ls I do see a /boot/grub/grub.conf and also a /etc/grub.conf - This grub.conf file says that boot=/dev/sdc (where the boot flag is with /dev/sda) and all references are to (hd2,0) whereas the "find /grub/grub.conf" always gives me "(hd0,0)" as said above. - There seems to be no /grub/grub.conf file on my system except under the /boot directory - I have also tried resetting the boot flag to /dev/sdc with fdisk, but that did not help either. - originally, I did set the system up on /dev/sdc by the way Am just trying to guess now what other combinations I could try. I already tried in BIOS to boot from all the different devices. No luck. (HowTos)
