Hi am a sco¡hool student, i recently bought suse 8.2 and istalled over my windos xp, suse configured everything and i could choose what system to boot, live was nice. Two days ago i was tring to make winxp safer but i couldnt,(This system is the most unsafe system microsoft could create), so i decided to go with win 2000 but my computer didnt run it so i was back to xp. The problem is thatknow winxp boots inmediatly and i cant acces my suse, and i dont have a boot disk. I know i can reinstall suse but that is the short and easy way, and becouse i love to learn i want to know how to reconfigure grub again and to be able to load suse again.
Thanks for your answer.

set your bios to boot from cd, put the first suse disk in and reboot, it will come to the install screen, one of the options is 'boot installed system' select that, boot into suse and use yast to re-install the boot loader.

or once in suse, at the root prompt enter grub-install /dev/hda

Sorry but i dont have the boot istalled option becouse it gibves me an erro when i choose it
