tri boots

[antonovich]

Hi,
I am trying to work out how to install another OS on my system - namely 
RH (either 7 or 8). Most books seem to work with that and I wanted to 
work through a book or two. I have been mostly just playing try and see 
up until now and it is getting a bit tedious... I have fstab currently as:
/dev/hda3 / ext3 defaults 1 1
/dev/hda2 /boot ext3 defaults 1 2
none /dev/pts devpts mode=0620 0 0
none /mnt/cdrom supermount 
dev=/dev/hdc,fs=auto,ro,--,iocharset=iso8859-15,codepage=850,umask=0 0 0
none /mnt/cdrom2 supermount 
dev=/dev/scd0,fs=auto,ro,--,iocharset=iso8859-15,codepage=850,umask=0 0 0
/dev/hda6 /mnt/f vfat iocharset=iso8859-15,codepage=850,umask=0 0 0
none /mnt/floppy supermount 
dev=/dev/fd0,fs=auto,--,iocharset=iso8859-15,sync,codepage=850,umask=0 0 0
/dev/hda1 /mnt/win_c ntfs iocharset=iso8859-15,ro,umask=0 0 0
none /proc proc defaults 0 0
/dev/hda5 swap swap defaults 0 0

I don't know whether it's visible from that but I have 4 primary 
partitions with 3 (?) virtual partitions in the last. I had another 32 
gig in fat32, but got rid of it to try and make space for a new 
partition for RH. The install disk just won't let me install on the new 
partition, or even make the new partition. In HardDrake (running 
Mandrake 9.1 and xp) I can create new partitions, but they won't format 
- most annoying. The RH installer seems to be saying that it will only 
install on / anyway, which means I would have to get rid of my Mandrake 
(or would I)? The idea is to have all three possible to boot into (MDK, 
RH, and XP). Is this possible, and if so, any pointers on how to do it?
Cheers
Anton
