    Windows Installation can't find drives.


    Hi!


    I'll get right to it. I have a vizio all in one desktop (CA24-A2 to be exact). I purchased it with windows 7 installed on it, and i upgraded it to windows 8. I decided to return back to windows 7 because the Metro UI always crashed 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. 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. I added some pictures below, hopefully it helps.

    On top of not reading the drives, windows 8 won't boot up now and i keep getting "bootmgr is missing" error. I would appreciate any help, I've been stuck on this for the last few days.

    from what I can see you are missing the system reserved partition, this is why you have this error

    Try loading your Sata controller drivers.

    I've checked vizio's website and couldn't find the SATA drivers there.

    I've tried that one already. Downloaded both windows 7 and 8 and placed them on a usb (formatted to NTFS) and when i insert the usb drive it shows the usb read, but no files on it.
