Updated ubuntu and xp gone

[Ni72ous]

Hi all

I installed ubuntu on my laptop, had xp installed fisrt, everything went fine, got it dual booting fine, managed to get
grub to boot from xp as default, then updated ubuntu, rebooted and xp is gone from grubs menu, can someone help me
put it back in grub please else i think i will just stick my xp cd in and blow ubuntu out

Thanks

There was no xp entry there, only duplicated entries for
ubuntu, managed to get it to work by adding the following

title windows
root (hd0,0)
chainloader +1

i am confused about what that does/means

Thanks for your help anyway, know any good linux noob sites?
