Hi there.

I had a dual boot xp\vista with Vista as bootloader

Now I installed Ubuntu 8.10 in the Vista partition formatting Vista.

The problem is now the Grub detects Ubuntu of course and Windows Vista (I dont know why because ubuntu deleted it and so it doesn't run) and no Xp.

Inside Ubuntu i can see Xp partition which is intact.

Can someone please tell how fix it?
I am new in Ubuntu, i dont know how config Grub.

I want to be able to run Xp and delete any entry of Vista.

Thanks in advance

It looks like the second Vista boot option goes to my previous dualboot screen (xp\Vista) that way i could boot xp again.

Is there any way i can boot Xp from Grub???

Plus why do i still have Vista boot files?

You still get Vista's boot menu because Vista normally puts its boot files in the XP partition when you install Vista after XP. To fix it, most likely all you need to do is boot your Windows XP Install CD, go to the "recovery console", and run:

fixboot

What that does is fix the XP partition boot sector so it boots "ntldr" (Windows XP) instead of "bootmgr" (Windows Vista). If that works OK, you can also remove the following Vista directory and boot file from your XP partition:

C:\Boot
C:\bootmgr
Let me know how that goes. :)

Thanks but before acting i want to ask something

XP may/probably overwrite the Grub boot-loader right? How can i backup my grub so i may easily restore it with the live cd?

Unless you reinstall XP or run "fixmbr" from the XP CD recovery console, your Grub in the MBR (Master Boot Record) should be safe from harm. The "fixboot" command only fixes XP's partition boot sector; it doesn't touch the MBR where Grub is. :)
