do you have a boot diskette for RH? If so you can erase the mbr with
fdisk /mbr in DOS mode, and then use your diskette to boot into linux and reinstall GRUB, or I would suggest install LILO.
Regarding books question, these two are a good start, espacially the second one, so I'd suggest to get any linux book, which goes deeper into details later on. Linux in Nutsell is an excellent refference for command line. And don't spend money on anything that is available for free on net (my suggestion too), there is a moderator on these forums with screen name acid_kewpie; in his signature there's a link to a handful of on-line books, check it out.
And please, don't double post it confuses ppl, and sometimes ppl get angry about it, espacially moderators.
