I just installed a copy of Fedora Core 4 on my computer, but when the install finishes and it prompts you to reboot the computer boots Windows XP instead of loading the GRUB bootloader I told it to install. This is the second computer I've installed Fedora on with very similar configurations, and it worked fine on the first. When I installed Fedora I did select Linux as the primary OS, so it seems that somehow Windows has a higher priority in the MBR. I am able to boot Fedora using a boot CD containing GRUB and typing in the necessary commands, but this is annoying, and the OS doesn't run the proper post install sequence it is supposed to. Any ideas? Thanks.

If you have 2 hard drives maybe you must change it to boot from other drive. If that`s not the case GRUB probably wasn`t set up correctly.
try again or find some livecd and fix it manually after reading this.

Did you install GRUB to the MBR? Kinda sounds like you didn't.

I thought I installed it on the MBR, but obviously it doesn't look like I did! I'll have to read more about it and try to get it straight. At least it works fine when it does boot! Thanks.

Look at the grub manual ( http://www.gnu.org/software/grub/manual/grub.html ) and read sections 3.3 “Installing GRUB using grub-install” and 3.2 “Installing GRUB natively”.

You already seem to know how to boot into the grub shell, so reinstalling it should be easy.
