You might think about installing RH9 rather than 7.2.
I have a dual boot (MS-Win2k and RH9) on a single hard disk and have partitioned it as follows...
C: Windows and Programs NTFS 4Gb
D: Data FAT32 5Gb
/boot Linux boot partion ext2 48Mb
/ Linux software and data ext3 6Gb
swap swap space linux swap 258Mb (2x RAM)
There's lots of different opinion about partition schemes, the above works for me and hasn't caused any problems. You should adapt it according to your setup, if you have lots of different users on the system you may want to have separate partitions for the 'core' linux programs and for user programs and data.
