WinXP ,RHEL ws-3 & FEDORA core 1 in 40 GB hard disk

Hi guys !
My machine already contains WIN XP & RHEL ws-3. And now i tried for the 3rd one FEDORA core-1.During my installation procedure the GRUB LOADER did not show RHEL(it shows only DOS and asks to select the loading priority). I tried a lot , i manually selected RHEL(root dir '\' & '\boot' in my grub loader) when my system boots it shows three OS but RHEL does't works or booting is failed.


I have alloted 30 GB for win xp
and 10 GB for RHEL( 9.4 for '/'
500MB for'swap' & 107 for '/boot')

available partitons before linux: C,D,E,F&G:
active partition C: WIN XP)
I deleted D: for RHEL and E: for FEDORA
For fedora ( i did the same partiton as RHEL)

I believe that type of kernel is Kernel2.xx
sorry sir if the version is wrong.If possible
guide me.

thanking you
Anand

First we need to know what partitions fedora core1 is on;while in RHEL post;
next need to see /etc/grub/grub.conf or /etc/grub/menu.lst so post that too;
