Hey maxmelbin,
what happen is your Red Hat 7.1 is some old now.
Don't know for sure, but probably is using LILO as bootloader and that limits the root partition to be
before the 1024th cylinder.
That means your last partition is too far from the disk beggining to install that Linux.
Now you have fallen back your system so no further help is need it. But considering your situation, I would choose another Linux distribution.
That's totally personal. If you want to consider my opinion, I would say:
Debian, definitely not.
Mandrake is very good.

Suse, probably the best, but is not possible to download it for free over the net.
Conectiva is the one:
ftp://ftp.unicamp.br/pub/conectiva/iso/
- Red Hat based
- good drivers (the only one worked my Nvidia card in one shot)
- lots of Windows codecs
- plays DVDs!! (Suse does not, you have to patch it)
- read and write
stable support for NTFS partitions
Another tip: do not use Fedora. After Red Hat has gone only payed, they left a very buggy and non friendly system -- my opinion, of course.
Probably all of them would handle your >1024 cylinder problem and boot both Linux and WinXP.
