Boot options

[Soren470]

Hey all, so I recently tried using Ubuntu's Wubi installer to install Ubuntu to a USB drive. It ended up freezing after restarting my computer, and now everytime my computer boots up it gives me the option to boot into Windows 7 or Ubuntu (not through the interface as if you have actually installed Ubuntu on your computer) is there a way to remove this? I just want my computer to boot up normally...it automatically boots into 7 if you wait like 5 seconds, but it would be nice to not even have to go through that if possible.

You can try reinstalling it.
Create bootable image in Unetbootin [i prefer it]
Burn to pendrive and boot into pendrive [Use F10 for boot option]
Perform a clean install on the existing EXT4 [Format it before installing]

Hope it helps
