Hello;
I have two operating systems on my PC, 1- Fedora 12 2- Windows XP.

when I re-install windows xp on PC yesterday, and reboot system, doesn't display grub menu to select a OS!!

I tried to repair it with fc12 DVD 32bit, but it doesn't have any option for repairing grub (fc10 DVD had this option!!)!
therefore I tried fix it with bellow way:

Code:

1. Resure install ...
go to shell and type:
2. chroot /mnt/sysimage
3. grub-install /dev/sda
4. exit
5. exit

and it without any error, said successfully done. when I reboot system and choose fedora from grub menu, fedora doesn't start and in black startup screen said:

Code:

SELinus target ...
take very times... dependence hard disk speed ....

what can I do for repairing it?
Very Thanks.

All of the install DVDs have the rescue option. It's called Rescue Installed System. It is from the shell in that feature that you use the commands you mention. Boot with the DVD. Choose Rescue Installed System. Step through until you get the command line.

Code:

sh 3.2#

This is where you type

Code:

chroot /mnt/sysimage
grub-install /dev/sda (typically /dev/sda)
exit
exit

System reboots and you should be able to load Fedora.
