Ubuntu, install failed and now I cant Uninstall

[Stellios]

Hi guys, need a bit of advice here.

I installed ubuntu on the rig in my sig, and it mustnt have gone in right as it kept erroring on boot. Ive went into the program manager in Vista and uninstalled it, but im still getting it as a boot option on boot and its still get the 30GB I allowed it have upon install, is there any way to solve this?

Also, was it just a bad install, or does Ubuntu not like quad core CPUs or something? Its on my laptop no bother, but it doesnt like my desktop.

Cheers for any advice.

Wait, Stellios said he uninstalled it in Vista which seems to indicate that he installed with Wubi. If so there won't be a partition to delete.

Stellios, is this the case?

Yeah, it was installed through Vista using the option "Install inside Windows" on the disks main menu. Ive not got a clue what Wubi is so I cant verify that bit though. When the install kept erroring upon booting into Ubuntu I used the program manager on Vista to remove Linux, but its left Ubunu as a boot option on turning ont eh PC, adn its still using the 30GB ive allocated it.

Sorry about the late reply.
