I have 1.5 tb, and i partionened for ubuntu, but Im instead going to but ubuntu on my laptop, so yea, i have a 1.3tb and a 200gb, pissing me off, i have no data on it yet, so how would i unpartition?
Oh, I see. You can use a livecd like GParted to delete the Ubuntu partition and expand the NTFS partition to take up the whole drive. This tool may be available on the Ubuntu disk; boot from it, start a terminal, and type "gparted". If it doesn't start properly, try "sudo gparted", and if that fails download the GParted disk and use that. It should be obvious how to delete the Ubuntu partition and resize the other one.
Use any decent partition manager util. Parted Magic is supposed to be a pretty good LiveCD for it. I think Windows Disk Management still sticks its head in the sand for other OS's filesystems, but fdisk should be able to wipe everything if you just want to start over.
