I previously had win xp pro and win server 2003 installed on my computer, and the windows boot loader to choose between them. I just installed ubuntu linux, and it installed the grub boot loader. The problem is, there is only one windows option there, and it takes me to the windows boot loader, so it's a 2 step process to boot into windows.

I want to remove the windows boot loader from my system completely, and have an option for win xp pro and win server 2003 in the grub boot loader. Anyone know how to do this?

Maybe you have to edit /boot/grub/menu.lst and you have do remove the lines about windows. But I don't know how to remove the rest on windowsite

Basically what you need to do is open grub.conf (menu.lst is a link to that file) and read the section where the windows boot procedure is described. It's something like:

windows
root (hd0,0)
chainload +1 (going from memory here)

now you should use this entry as a basis for creating two differnt entries something like this

Windows XP
root (hd0,1)
chainload +1

and

Windows NT
root (hd0,2)
chainload +1

where hd0,0 describes the first hard disk first partition (grub starts counting at 0), hd02 = 1st HD 3rd partition...

Save and close, you're ready.
