i recently installed a version of ubuntu 8.04 on my external usb drive.
i can start from the external drive but when i try to start the computer without the drive plugged in i get the following error:

can anyone tell me how to get my computer back to its original state, being able to start without the external drive plugged in?
thanks in advance for any help!

What do you have on your internal drive? Was it windows or linux?
