Hi,

1 ) I have accidently installed RHEL5.2 in a lap which was already having Fedora14. Now the fedora grub is missing and i am unable to boot into fedora.

also there is no Rescue option in fedora 14 live CD, it only have Boot, Basic video, Memory test but no rescue mode. so pls tell me how to get into Rescue mode and solve this problem


2 ) How to find in which partition it is installed eg do i have type (hd0,0) or (hd0,xx), i have on hard disk so the H.D.D number will be hd0 but what about the partition . how to find it . pls help me

Have you tried boot?

it just boot into the live CD

If you have the install media for RHEL5.2, boot from it and type

linux rescue

at the prompt as soon as it gives you the very first screen ie 'what install mode do you want? '

I know how to boot into rescue mode in Redhat and i already did.

but want to know how to enter in Fedora.

Should be the same

If fedora live-cd is like ububtu desktop when you boot in the example files are actually linked to your own. If you look around you'll see that all of your files.
If fedora is still there and redhat has atleast a 2.6.32 kernel you'll be able to find your way to a terminal in
usr/share/applications double click on terminal it opens.
enter command
"sudo os-prober"
"sudo update-grub"
reboot
