Just read the Valid thread thingy so I am trying again.

I loaded Back Track into VM using a 32 bit ISO burned to disc.

I cannot now boot into anything and I urgently need my windows boot back - I mean really urgently.
When I boot the computer all it says is that BGRUb (or something) cannot be found. I thought installing into a virtual disc had no effect on anything but that disc so how come it has affected the boot sequence of my computer.

Urgently need help to get my windows to boot so please, please could someone give me a step-by-step.

I loaded Back track to learn but now wish I hadn't.
