Hi folks,
FedoraCore5_64
Grub on this box did not work ever since running "yum update" updating "kernel-2.6.16-1.2133_FC5" a few days ago. On starting the PC only with "GRUB" popup on a black screen without other messages. Typing does not work, keystroke without function. I have to run a boot floppy to start the box/PC.
# uname -a
Code:
Linux localhost.localdomain 2.6.16-1.2133_FC5 #1 SMP Tue Jun 6 00:51:53 EDT 2006 x86_64 x86_64 x86_64 GNU/Linux
# rpm -qa kernel
Code:
kernel-2.6.16-1.2133_FC5
kernel-2.6.16-1.2122_FC5
The boot floppy was created on this box with
Code:
# grub
grub> root (hda0,0)
setup (fd0)
I tried to fix the problem with the boot floppy without success. Steps performed as follows;
# fdisk -l
Code:

After starting the box/PC with the boot floppy
1)
On Konsole;
# grub

Done.
Exited grub and rebooted the box/PC. Still failed to boot the box/PC with only "GRUB" displayed on a black screen, no other messages. Keystroke did not work.

Error 17: Cannot mount selected partition
Failed. Whether I need to mount the /boot partition (/dev/sda1) first before running "grub"? The HD is working. Would it make confusion resulting in re-installing the complete FC5_64.
Besides I can't mount the boot floppy, either as root or as user, to copy "grub" from it on /boot
$ cat /etc/fstab
Code:
...
....
/dev/fd0 /mnt/floppy auto noauto,owner,user,kudzu 0 0
However I can mount a floppy with .txt files on it only by running "mount /mnt/floppy"
It looks strange to me. Would the boot floppy only contain an image.
Please advise. TIA
B.R.
