Hi! I purchased a vizio all in one desktop model CA24-A2 , with windows 7 installed. I upgraded it to windows 8, but decided to return back to windows 7 because the Metro UI always crashes on me. I purchased a windows 7 disc and booted the computer off the disc. When the installation asks which drive to install it to, nothing appears. For some reason, the installation disc is not reading the drives. I've checked vizio's page, but didn't find any drivers for the hard drive that would work. I check the Bios menu and both drives appear. I've read on other forum about changing the bios mode (AHCI,IDE), but my bios menu is very restricted, and i dont have that option available. I used MiniTool Partition wizard on a bootable cd, and it was able to see my hard drives as well. I added some pictures below, hopefully it helps. When i try to boot windows with windows 8, "bootmgr is missing" error appears. After restarting my computer several times it seems i only have access to the bios menu f2, and not f8 for recovery. I would appreciate any help, I've been stuck on this for the last few days. Thanks in advance.
