Heyo, I browsed through the forums for an answer to this but much of it assumes I have any idea as to what I'm doing, which is unfortunately untrue
I started out with Windows XP on my machine, and when I started learning about Linux I partitioned off about 2.1 gigs to Mandrake 9.2 (using Mandrake's partitioner in the installer.) to try it out. Later on I tossed Mandrake out and put Red Hat 9 on that partition, which is labelled as hda3. It ran great, and being a clueless Linux noob I was glad that the learning curve wasn't as bad as I'd been lead to believe.
Anyways, a few weeks later, a friend of mine pointed out that I had a partition that wasn't being used for anything; hda2 was just 100 megs with nothing on it; it was just a chunk of space formatted as... hm, I think it was a Linux Swap or it might've been Linux Ext2. He offered to use his copy of Partition Magic to format it to FAT so XP could read it, and I said "sure, why not?"
Well, evidently that wasn't a smart idea at all. The pretty bootloading screen that came with RedHat that lists all my hda's has been replaced with a Grub command line prompt. Now, I'm still a Linux noob, and this strikes me as way out of my league. I perused through these forums yesterday afternoon and found a way to boot into XP from it (seriously, I love you guys,) but after reading through various sources like uruk.org's grub manual I still can't figure out how to boot into Red Hat 9. I understand that you have to do a couple of things such as load the kernel and whatnot... that kinda makes sense. But to tell you the truth I really don't know what I should be filling for parameters in those commands, because I'd never really gotten so far into Linux to the point of understanding the kernel. I was mostly just messing around in the development environment.
I tried to just reinstall Red Hat, but something's screwy about the CD and I'm way, way too low in cash to go out and buy another stack. So what should I be typing out, exactly, to boot Red Hat from Grub, or at least how can I find out what parameters I'm supposed to be filling in?
