Arrow Need Help, cant boot into redhat or xp??


Im having a little problem right now. This was my setp up 2 weeks ago

2 HDD
DRIVE A==>XP
DRIVE B==>REDHAT9. Then I decided to go out and buy another HD and install other distros on the new drive without messing with the data i had on the drive B. So I removed Drive B and install the new drive(i'll call it C for continuity). Proceeded to install FC2, everything went fine. Today I decided to remove drive C and reinstall drive B so i can access some data on that drive. Now it boots, it comes to the screen where grub appears and just hangs there. I can boot into rescue mode but dont know what to do next. Can someone point in the right direction. I want to edit grub.conf so i have the option of xp or redhat9. thanks in advance for your help. Another questions, if and when i decided to reinstall Drive C, am I going to have the same problem??

hi

boot from a FC2 cd using "linux rescue" at the boot prompt

follow the instructions there

at the end
#chroot /mnt/sysimage

then do

#vi /etc/grub.conf

reboot

thanks for the reply massand, but i want to be able to boot into redhat9 which is
different hard drive than fedora core2. I want to be able to boot into rescue mode
using redhat9 cd which i did and got to the shelll prompt and typed chroot /mnt/
sysimage. I dont understand why this is happening. 'Grub is installed on botgh
drives, the one with Fedora and the one with Redhat9. what lines do i have to add to grub.conf to restore to its original default configuration?? thanks in advance

hi there

this will read ur grub.conf from /etc/grub.conf and write according to that to ur MBR

u can edit ur grub.conf bu editing the /etc/grub.conf

also to remove grub at l;ater stage so that u can boot int windows

try this

boot from a win98 cd
at the command prompt
#fdisk /mbr
will remve grub and rewrite the windows MBR to it


or boot from a winxp/200 cd in to recovery console
and use "fixmbr"


regards
