Can't install Windows 7 Ultimate x64

So as soon as it finishes, what do I do?

Disable the second HD as suggested repeatedly.

If you are cleaning Disk 0, then I assume you want to install Windows to Disk 0.

Have you yet disabled or disconnected the other disk, presumably Disk 1??

You only want 1 disk to be available to Windows when you begin the installation, so you need to disable or disconnect the unwanted disc.

If you open the case and disconnect something, you are going to have to know the answer to the question "which of these two discs is disk 0 and which is disk 1"?

I will look in my manual after cleaning how to disable disk 1 - it is disk 1 and not yet disabled or removed.

See Greg's post number 80. The info should be on page 23 of your manual.

You need to select 'disabled" for the drive in question.

Confirm that the DVD drive is set to boot first.

Save the changes to the bios and then exit.

Then put the install disk in the DVD drive and restart.

If you have a disabled hard drive and a newly cleaned hard drive, you have no OS, so the PC should start (boot) from the disc in the DVD drive and you can continue the install.

The "clean all" command you issued takes about an hour for each 300 GB of drive space on the drive.

How do I disable the drive?

You generally navigate among BIOS choices with the arrow keys. And then maybe hit the enter key after you have arrived at the proper spot via the arrow keys. Then save the changes and exit.

If the BIOS is too much for you to deal with, your only other choice is to open the case and unplug the unwanted drive.

Three options are AHCI, IDE and RAID. No disable.

The BIOS Manual says Disabled should be one of the options (see screenshot above). If it's not then I don't see where else HD can be disabled in BIOS. Anyone else?

In that case I'd open the case and pull the power cable from the bottom HD.
