Major trouble with re-installing Windows 7
Hello everyone,

I am new to this Windows 7 Forum.

I have a Sony Vaio laptop which I did not originally purchase but traded for my iPod touch. This Vaio has a Windows Vista sticker, but the man I got it from told me he installed Windows 7 Ultimate on it. He did not tell me that it was a Release Candidate version. I found that out after 2 hours of using this PC, when it suddenly restarted.
After June 1 it began notifying me of the RC issue, it being expired.

So, this week I finally decided to get rid of the RC version. I purchased a new Windows 7 Ultimate package and downloaded KillDisk (Active@ Kill Disk Hard Drive Eraser. Low Level Format.) to swipe my hard drive clean. I burnt KillDisk onto a DVD and ran the program, which was successful.

Afterwards I bought a new Windows 7 Ultimate package, tried to run the DVD but it now gives me the error "Operating System Not Found".

The BIOS on this Vaio model does not have a whole lot of settings to change, so what do I do???
