View Full Version : [ubuntu] Dual boot with XP - but only boots into Ubuntu!

Hi all,
I installed Ubuntu on a partition I created on my 60Gb hard drive, after the windows XP partition, and I'm quite impressed with everything it does. After a couple of days playing, however, I have realised I have no way of booting in XP as GRUB doesn't give it to me in the list of options at startup.

It is probably also worth noting that actually creating the Linux partition was a right pain, as GParted wouldn't (and still doesn't) read properly from the NTFS XP partition. I had to use Partition Logic to resize and create the partitions.

The Ubuntu partition is experimental and expendable - the XP partition is ultimately expendable but I wouldn't mind being able to get back at it.

Cheers for any help,

Mike

Thanks for the quick reply :-)

I did that, and Windows XP appeared in the list, but GRUB gave me "Error 1: Filename must be either an absolute pathname or blocklist" when choosing the XP option.

I tried the method that seemed to work in this thread (http://ubuntuforums.org/showthread.php?t=372070), i.e. removing the savedefault line, but that still threw up the same message.

Eurgh...

Remove 'makeactive' and see what happens.

Ok, I gave that a go but the same error appears when I try to boot into XP. I think I'm prepared to sacrifice Ubuntu now for the moment - seems to be giving me a lot of hassle - is there a way to completely remove it, leaving me with XP only? Will the computer then boot into XP?

Cheers.

chainloader + 1

This is the culprit. It needs to be


chainloader +1
(no space between "+" and "1")
