You need to boot from the Windows 7 DVD.

To repeat: do you know how to set the BIOS to boot from the DVD drive first, before any hard drive?
Sorry, but it wont boot from DVD

Regardless of which installation disc you use?

Is your DVD drive KNOWN to be good?

Does the DVD drive work normally in all respects?

You can install 64 bit over the top of 32 bit, you just must boot the DVD.

If it fails when DVD drive is set first in BIOS setup as shown in tutorial I posted, then try tapping the one-time BIOS Boot Menu key at boot.

Why do you keep telling us about command lines and error prompts that only mean you are not booting the DVD? Boot the DVD, period.

If it won't boot via either method then confirm the ISO or burn another using the ISO download for your licensed version and tools provided in Clean Reinstall - Factory OEM Windows 7

When you were in the BIOS, did you:

1: change the boot priority to boot from the DVD drive first?

and then

2: Save those settings and exit the BIOS and reboot?

and then

3: Put the Windows installation disc in the DVD drive and restart?

This is where i went wrong.
i already had the 32 bit version installed.... and tried to upgrade to the 64 bit version.....and it clearly says you cant do that.
"If you have a 32-bit (x86) Windows 7 currently installed, then you must use a 32-bit Windows 7 installation disc to be able to do a repair install with."

As stated you must do a Clean Reinstall to change from 32- to 64-bit.

As it states in the tutorial I linked for you you must back up your files and reinstall your programs: Clean Reinstall - Factory OEM Windows 7.

Nothing will be saved which you do not back up first. Read the tutorial, which is the same for retail as for Factory OEM.

In post #5 you stated that you have both 32-bit and 64-bit discs for Windows 7.

So I am wondering why you are downloading an ISO?

If you want to install 64-bit, you don't need the 32-bit disc.
