Okay, I had installed FC5 on my harddrive using pretty much the default
options, then (much later) I put in a second hard-drive and decided to
install Windows I deleted the First small petition on the first hard
drive and everything else on the second and installed Windows. [For some
reason it didn't work, so I gave up on windows.] Thats when I realized I
couldn't boot Fedora anymore. I tried searching for a way to reinstall
GRUB (such as the rescue disk and so forth) eventually I just
reinstalled Fedora Core 5 on the second Hard Disk. Now I have GRUB back
but it only boots the second FC5 instilation. What I need is to be able
to boot the First instillation on the First Hard Disk.
The best way is to use the rescue CD and it should give you a choice as
to which installation to boot, if it sees both installations.
What you want to do so your system is easily manageable is to install
one grub installation to the partition that has your /boot partition on.
You can do this by booting into the system, choosing the appropriate
version, chroot /mnt sysimage and then running grub-install for say
/dev/hdb1 for grub to install into your second installations partition.
grub-install /dev/hdb1 for example with your secondary drive
installation selected.
To get your first installation back, select it as a choice from the menu
the rescue CD should detect. (or first install disc using linux rescue)
Once initiated, running chroot /mnt/sysimage and finally running:
grub-install /dev/hda to install onto the MBR. You next need to add a
chainloader entry into grub to chainload the second drive installation
where the grub primary stage is installed into the /boot partition.
The later stages of grub are under /boot/grub. Running grub-install
should set things up correctly for you.
Easier done than said,
