Recently, I installed RHEL first with 3 partitions(/, /boot and /home) and I also created one FAT partition for installing Windows XP. After installing RHEL, I installed MS Windows XP. This left grup being replaced by MS Windows boot loader in MBR. How to restore grub?
Restoring grub boot loader should be trivial if you have the installer CD. In case of RHEL (or Fedora or CentOS), what you have to do is by inserting disc 1 of RHEL disc sets and type linux rescue. After answering a few questions, you will be dropped to console. What next? Type grub-install /dev/hda. This command will install grub boot loader into MBR.
Before this I have been googling for about an hour. The answers I found always like this:
1. chroot /mnt/sysimage
2. /sbin/grub-install --recheck /dev/hda
I had error with those steps. Step 1 means to change your root dir to installed partition which is mounted under /mnt/sysimage directory. If you have no luck, skip step 1 and go straight to step 2. Good luck!.
