Deleting XP Partition

Hi There!
i need some help with my vista, i want to delete my Windows XP Pro partition on my HDD as i am running out of space, when i goto disk management in admin tools it doesn't give me the option to delete as it is non-clickable, i also want to merge the XP partition once i've deleted it. My OS is Windows Vista Ultimate 32 bit,
thanks in advance

Is XP listed as boot partition drive C:? If it is, you need to backup and reinstall.

is that my only choice?
can i remove it from the boot list?

Not if its the boot partition. It contains the boot.ini, ntldr and other boot files. The registry is set to boot from this partition. The only way to remove it is backup and remove all partitions, repartition and reinstall then restore data after reinstalling the apps.

is that my only choice?
can i remove it from the boot list?

Yes.

You could get a larger hard drive and use Acronis to image to a larger drive.

woops sry posted tht agn i duno how lol
if i make a full backup using the backup utility would i be able to wipe it and restore it using the restore function on the cd?

No. You have drive C: for XP and boot files. D: or another drive letter for Vista. You can't remove C: without causing the computer to never reboot. You can backup to an external drive and reinstall just Vista, apps and restore data.

according to my vista it has C:\ drive and XP is D:\ but if i remember properly in xp it has C:\ and vista had D:\ so would my only main option is to delete both partitions and just reinstall completely?

Your best solution is backup and reinstall completely from fresh drives.

that sounds fun lol thank you for your advice, i might go to that sometime this weekend

It sucks I know. I used to dual boot.

yea, it was a bad idea putting xp on here lol i just wanted to have it there for programs that wont work on vista but i now use virtual pc for that, annoyingly i am running out of space on my vista so i have to delete it
