Errors while Reinstalling GRUB

I have intel core 2 duo 1.86 GHZ , Nvidia 7100gs , 1 GB ram , 2 hard disks (250 GB, 160GB) with ubuntu on 2nd one,dunno what all i should tell more

.

My prob:- after ubuntu's reinstallation grub fails to recognize xp even after GRUBs reinstallation

When i downloaded an ubuntu iso(Bfore 2-3 months) had Xp on my comp.
i was happy and GRUB was working okay.but due to a hard disk failure or Sumthin and i had to reformat the drive and reinstall ubuntu. i made a big mistake by not fixing the MBR by xp cd.Now Grub doesnt recognize windows but with some advice of a friend(here on this forum) i Fixed the MBR with the xp cd.NOw while booting with live cd and reinstalling GRUB by

grub-install /dev/sda

i get error : Could not find the device for /boot : Not found or not a block device.
and on the DIGIT irc Hitboxx told me 2 do

chroot /mnt/sysimage

while doing this i get an error : no such file or directory

Now i cant boot into linux,
and if i select the linux drive i get error : NTLDR not found.

PLEASE HELP MEEEE.
IM STUCK WITH CR@PPY WINDOWS

This mite help u

Thanx for the link sunny,
ill try it 2moro.(no empty cd 2day

Can you see the XP entry when in the Grub menu during start-up.?
If not, then add the folowing entry to /boot/grub/menu.lst file

title Windows XP
root (hd0,0)
makeactive
chainloader +1

Right after the Ubuntu entry.Change (hd0,0) to the location of your XP partition

NOTE: Do this after you re-install grub from the link given by Sunny.

i dont think i want this.

and after reinstalling GRUB when booting ubuntu it hangs or stops @ about 1% and i have to restart

yes,as @shady's post,make sure "makeactive" line is there for windows in menu.lst.

if u have ur grub corrupted,ie no proper display ,but only a grub> prompt,u'd like to reinstall grub.
it is also good to see the output of below command from terminal in livecd

Code:

/sbin/fdisk  -l

ok ill do /sbin/fdisk -1, but after reinstalling GRUB when booting ubuntu it hangs or stops @ about 1% and i have to restart..

EDIT
BAH....... IM reinstalling UBUNTU

^it is "/sbin/fdisk -l" "l" as in small letter "L"

Doesnt matter im thinking of reinstalling it now or should i wait for stable version of hardy

reinstalling,formatting things are for window$ series of operating systems.In Linux,we can solve most of the problems.last choice is re-install

arre its hangin while booting, any way to repair it
