i had a windows xp on the primary partition of my hard disk and a fedora core 4 on the second partition. in all i had 4 NTFS partition and /boot, /, /swap partition on my 80 gb.everything is working fine till here. now i reinstalled windows xp and the grub is not working. i found some help regarding reinstallation of grub, where u have to enter in rescue mode then chroot /mnt/sysimage and then grub etc. but this is not working.

now my windows is working fine. give me some solution.
thanks in advance. awaiting ur reply

Welcome to LQ.org champion. Well, you are pretty close to fix it

. In fact, you just need to reinstall GRUB with one command after booting into rescue mode:

chroot /mnt/sysimage
grub-install /dev/hda

That assumes that you want grub re-installed to the MBR. Note: use hda, not hda1. If you have sATA disks, most likely it's sda, ratter then hda. Did you try that?

Regards!

strat linux rescue
then try this command
dd if=/dev/hdX of=/linux.bin bs=512 count=1
where hdX is your /boot
this have to copy your linux boot to C:\linux.bin
then update tour boot.ini and add this line
c:\linux.bin = " Fedora Core "
must work
