mbr after xp install

after booting into windows for the first time in months, it seems like performance really isnt too good. im not sure if it is bc im used to the quickness of linux, but i decided that i am going to reinstall xp. i know this will mess up my mbr, and was wondering how difficult it is to reinstall grub?

thanks in advance.

Easy. Boot with a linux live CD and then follow scenario B5 from here.

i wanted just let people know that i was able to fix this issue. i was able to restore grub successfully from the following directions.

Quote:

1. Boot from a Live CD, like Ubuntu Live, Knoppix, Mepis, or similar.

2. Open a Terminal. Go SuperUser (that is, type "su"). Enter root passwords as necessary.

3. Type "grub" which makes a GRUB prompt appear.

4. Type "find /boot/grub/stage1". You'll get a response like "(hd0)" or in my case "(hd0,3)". Use whatever your computer spits out for the following lines.

5. Type "root (hd0,3)".

6. Type "setup (hd0,3)". This is key. Other instructions say to use "(hd0)", and that's fine if you want to write GRUB to the MBR. If you want to write it to your linux root partition, then you want the number after the comma, such as "(hd0,3)".

7. Type "quit".

8. Restart the system. Remove the bootable CD.

Hope this helps. Since I use Norton Ghost to make regular backups and restores (I do a lot of testing), I do this all the time...

hope this help people in the future.

which distribution are u using ? if its mandriva, put your installation dvd/cd into the drive and type rescue, then read and etc

it will rewrite your boot loader
