I tried to install ubuntu 10.04 to a 16 gig thumb drive and the installation went perfectly. However, when I removed the thumb drive and tried to boot the computer back into windows I saw that the installer had installed GRUB on to the hard drive of the computer. Windows runs fine, but it wont start with out the thumb drive that has the ubuntu install on it, this is very bad for me. Is there a way I can remove GRUB with out messing up windows on the computer? i dont have a windows 7 boot disk so this operation would need to be done either in windows (already booted) or ubuntu.
