Problem with Dell Inspiron 1501 laptop computer?

My Dell Laptop Keyboard won't boot at this point. It was running windows 7 ultimate, then I wanted to do a clean install of it as it was becoming bloated. So I took my Windows 7 Install DVD and put it in. I started from the DVD, as you should when doing this, and selected re-format my Hard drive within setup. I then attempted to install to it. It kept giving me an error upon install, so I shut down the computer, took out the Ultimate DVD and tried using my Home Professional DVD. I turned the computer back on and if gives me this exact screen:



Windows failed to start. A recent Dell Laptop Keyboard change might be the cause. To fix the problem:



1. Insert your windows installation disc and restart your computer.

2. Choose your language settings, and then click "Next."

3. Click "Repair your computer."



If you do not have this disc, contact your system administrator or computer manufacturer for assistance.





Status: 0xc000000f

Info: The boot selection failed because a required device is inaccessible.





I've tried pressing F12 and selecting the Dell Laptop Keyboard as the boot, but it just ends up bringing me to this screen still. I've tried resetting the BiOS back to default, that didn't work. I've tried setting the boot order in BiOS, that didn't work either. Please any suggestions?

If you need to further talk to me for it, here's my Skype.
