Experimenting with Linux? Having problems with GRUB? Grub is a boot loader, and a very nice one at that, but even the best tools need sharpening occasionally. I have been having problems with grub since moving the boot files to another drive - something is keeping grub from seeing them correctly, even though when I boot grub manually it works fine. I assumed it had something to do with getting grub installed into the correct mbr. I had performed the setup step inside grub, but didn't know about the grub-install step! This web site was a great help - GRUB HOWTO.
