Use this guide.

It contains everything you need to know by section:

https://help.ubuntu.com/community/WindowsDualBoot

Also, please type properly. Posts can be hard to read with all the contracted words.

if you post your /boot/grub/menu.lst or /boot/grub/grub.conf (2 names for the same file)
(in [code] ... [/code] tags to make it easier to read)

then somone can probably talk you through it

this is how my memory partitions are organized...now according to this tell me what should be placed in the root line.....
title Windows xp
root (hd0,1)

pls let me know as early as possible

What currently boots - the Windows bootloader or grub (i.e. which menu do you see) ???.
What operating system(s) successfully loads once you select it ???.

as i have 2 different hard disks for each operating system...i do not know how to edit the windows boot file...i know how to edit the linux boot file but i am unable to understand the exact partition[exhd0,0)] to be given in the menu.lst file...
so kindly suggest me the appropriate partition....by analyzing my previous post...

Answer the questions asked.

In your first post you indicate you have xp on one drive and Ubuntu on another drive. It also shows the first drive (sda) containing one extended partition and four logical partitions with Ubuntu on sda7. You have two windows partitions on the drive (sda5 and sda6)with Ubuntu which are both logical partitions. I assume your xp is on sdb1 as that is the only primary partition on that drive and is marked active (bootable). Assuming you have installed Grub to the mbr of sda, the entry in menu.lst for windows should be:

titile windows xp
rootnoverify (hd1,0)
map (hd0) (hd1)
map (hd1) (hd0)
chainloader +1

If you haven't installed Grub to the mbr on sda, you need to do do:

sudo grub #you will get a grub prompt (grub> where you enter the following:

root (hd0,6)
setup (hd0)
quit

You have sda1 marked active even though it's just an extended partition. I also am not sure if you will be able to access the data on sda5 and sda6 or if those are just data partitions? Windows will boot from a logical partition if you have another version of windows on a primary on the same drive. Don't know if it works if the primary is on another drive? You referred in your original post to xp on the first and Ubuntu on the second drive. I'm not sure if that is just the way you refer to them but your Ubuntu sees it the opposite, with Ubuntu on sda and xp on sdb. If you have switched boot priorit in the BIOS since posting the fdisk this won't work!

Since you indicated you were currently booting from windows, I assume you know how to boot Ubuntu from xp bootloader?

i gave you the best possible info if u have understood the previous posts.......

thank you very much...i ll try and let you know if it worked or not...newy thnks 4 helpin me

Read the GRUB documentation to find out what each of the commands does.

Grub doesn't actually read or boot windows, it chainloads them. The map commands are to make windows think it's on the first drive which it needs because of its large ego. Best thing to do though is as Nylex suggests, read the manual. You can get detailed explanations from the Grub Manual. Here's a link to it:
