Right there is a big problem. Windows 8 is on DVD so you can't boot it yet.
Besides that issue, I don't see a full make and model so no one can see if the BIOS settings are documented.
I am trying to reinstall windows 8 on my desktop and did a reset from the system in windows, which worked it got rid of the virus. But to make sure everything is really gone what I really want to do is clean the hard drive by doing a complete wipe and reinstall and new copy of windows 8 that I have which contains a product key I have. Back in 2011 I bought the computer and windows 8 failed (it kept saying it needed to be activated, we tried to enter the product key, didn't work, after several months of issues with our retailer and Computer manufacturer found out it had to be reinstalled remotely by Microsoft so as of now I have Windows 8 on my desktop but do not have a product key. So I purchased a copy of Windows 8 with a product key but can't install it.
The problem is my computer does not boot first from the CD drive then the hard drive. I can't find where to change this. I tried to go to the BIOS to change it but there is no prompt to select the CD drive. if anyone has any suggestions I would appreciate any help I can get. I have a screen shot of the BIOS but don't know how to post it.
