Ubuntu Installation :: GRUB 2 Does Not Recognize Or Boot Into Windows XP?

i can't boot up my win XP after installing Ubuntu 10.10.

I decided to replace my Vista partition with Ubuntu 10.10 so i redo my partitions and split the current Vista partition to a swap and root partition and install Ubuntu 10.10

Everything went well and i got Ubuntu up and running. However, i realize that GRUB 2 didn't recognize my existing windows partition. I double-check on grub.cfg and see that the default os_prober didn't recognize my XP partition either.

After search on the internet for a while, i found many similar issue where most are fix when manually adding the entry yourself so i decided to add an entry 11_XP under /ect/grub.d/ for windows XP and confirm that the new entry are added to the update grub.cfg file before restarting

Code:
### BEGIN /etc/grub.d/11_XP ###
menuentry "Windows XP" {
set root=(hd0,5)
insmod chain
drivemap -s (hd0)

[Code].....
