try boot with XP CD again & remove the non-dos partition from there.

U may try to remove the whole partition...and create the partition aagin...

If you have problems with XP as well, you probably need to fix the MBR... do some google.

try gparted, works well for me

My brother install Ubuntu before also...
I use to format the Ubuntu using Windows bootable disc delete and make a new format it in Windows....
You can try it...

Hi,

As what howszat said, after you remove your parition, you will not be able to boot to the windows anymore since the bootloader (eg: grub for ubuntu) has been removed. So in order to boot your windows like previous, you need start your windows installation cd and go to recovery console to fix the MBR.

I remembered I did this thing before long time ago, but if this is not working for you, maybe you can try the google to find out the solution. If your problem still cannot be solved, then only seek for help here.
