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 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 kernel-2.6.16-1.2133_FC5 kernel-2.6.16-1.2122_FC5 The boot floppy was created on this box with # grub grub> root (hda0,0) setup (fd0) I tried to fix the problem with the boot floppy without success.

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 ... .... /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. SL
