Hi all!

Well i have a little problem... can't get into linux... i did
install winXP and it took over my MBR and i don't know
how to fix this... i have search the forum but can't find nothing at all...

so my question is... how can i erase my MBR from linux
(RedHat 8.0 kde) and how to make my partition active!??

any more ideas!??

thanx!

This kills me. Floppy disks are dirt cheap but nobody ever makes a boot disk!!!

Anyway, hopefully you still have your install CDs. Put disk one in and type "linux rescue" at the prompt. Answer the questions until it searches for your system and mounts it. do a "chroot /mnt/sysimage" then reinstall grub. The command is either grub-install, or install-grub, can't remember offhand. Make sure you add windows xp to grub.conf, then reboot. Grub will give you the choice.

This time, make a boot floppy....

Have a look in /sbin for the command. Don't forget to make the appropriate changes in grub.conf.

Grub device names are indexed from 0. (hd0,4) is equivalent to hda5.

type in grub at the root prompt. It will probe devices and give you a prompt.
Enter

Code:

root <boot partition-or-root if you dont have a separate /boot>
setup <device-in-whose-bootsector-grub-will-be-installed>
quit

Thats it.
