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???

My DVD drive is at first boot and it still gives me the same error.

I obviously wouldn't boot from the hard drive now as it is completely empty.

Did you buy an upgrade disc or a full retail/oem disc? Did you install Windows 7?

I bought a brandnew full version of Windows 7 Ultimate.

This Vaio laptop came with the RC version of Windows 7 Ultimate, which expired now.

I should but I probably need to get an 8GB USB stick first. My 4GB USB stick is too small.

I copies the .ISO image onto my USB stick and tried booting from it.

I got the following error:

Disk Read Error
Press Ctrl+Alt+Del to restart.
