Adding GRUB after the fact?

Phil Healey · 06-25-2003, 09:49 PM

I'm running RH9.0 on a Dell Dimension 4550 which came with WinXP pre-installed. During the installation, the program "strongly recommended" I make a boot disk because of GRUB problems with WinXP. Fearful of losing my Windows partition (good indicator of newbie-ness) I forewent installation of GRUB and now boot with a boot disk. This is getting to be a hassle, and now that I know a bit more about what's going on, I was wondering if there's a way to install GRUB now, with everything in place.

Thanks for the advice,
Phil

yes simply type grub-install as root
make sure /boot/grub/grub.conf is set up properly

How do I know if it's set up properly? That is, where can I find out what the various hda partitions are?

Take a look at the /etc/fstab.

Here's my grub.conf file to serve as a guide.
