I had a virus on my Dell Precision 5810, removed it using Malwarebytes, however continued to have misc problems. Decided to just wipe the hard drive using the Windows 7 SP1 64 Bit disk. I am doing the basic-hit F12 on start up, choose run from CD, files load properly, however when it gets to the step on picking which partition to use it says there are no available drives. Usually at this step I would choose the already used partition delete it, create new and be on my way. Is there something that would be causing the C drive to be hidden? I can run the Windows 7 install when I am already logged in and it will give me the option to delete the files but says it will keep the old files as windows.old. I am not sure if this will give me the same result as running it from the CD at startup. I want to make sure there are no remnants of the prior installation.
Thank you for your help!
