    This is what I meant, the UEFI boot mode. I get the idea that this was introduced with Win 8, but has backwards compatibility for win 7 and earlier with legacy mode (for when I install windows 7). I gotta go somewhere right now but will get some pics up in a few hours.

    Here's some images. I also disabled the secure boot when trying the medicat and win 8 repair discs, which did nothing.





    this is the screen that displays upon boot






    when pressing F2 I can run diagnostics test





    F10 enters bios, shouldn't I see the hdd and optical drive here?





    boot order


    F11 goes to a recovery option, but that does nothing and brings be back to the boot screen (top image).

    I finally got it to read a disc. I found my external usb dvd drive and got my retail Windows 7 install disc to boot. I'm not sure if I want to install that though. Not quite sure why I couldn't get the medicat dvd to boot? And, why wouldn't the win 7 disc boot from the internal dvd drive? Leads me to believe there is an additional hardware issue.

    I'm glad you got it working. You could always "obtain" an OEM Windows 8 iso and repair your install.

    That's what I was thinking. Getting windows to boot on it would be a relief, then I could do further diagnosing if need be.

    Recommend a program to me that will let me create a bootable usb drive so I can try the medicat iso.

    Medicat doesn't work from USB for some reason. I don't know why.

    Now I'm getting somewhere. I got a Win 8 install ISO to boot from usb thumb drive. I really cannot do much, it wont install Win 8 to the primary partition. Just trying to get some ideas on what to do here. I would assume that the 347GB unallocated space is suppose to be part of the 92GB primary partition but got screwed up due to a bad formatting. As you can see in the highlighted partition, I cannot do much with it except resize it. I think my only options are to shrink the unallocated space and increase the primary partition and format it, and hope that once it's formatted I can then enter the recovery option or install a fresh copy of Win 8 from the usb key. I've already went through all the recovery options on the repair disc with no luck. Earlier I had it attempt a repair, but after a while I went and looked at it and the pc shut down, maybe from heat? I lifted it from the table a bit to give the vent more breathing room so maybe it wont shut down this time. If it cannot do a repair then I'm just going to format the drive.

    You don't want a re-install, you want a repair. Try switching it back to UEFI mode.

    My thinking is, if I can re-install the OS on the primary partition then maybe I will be able to access the recovery, but that don't look like it's going to happen because recovery don't work with the Win 8 repair from the usb key.

    I couldn't get the usb key to boot in UEFI mode, I can't get anything to happen in UEFI mode. When I switch it to Legacy mode I can get the usb key to boot and also the Win 7 disc from a usb dvd drive.

    I tried to do a repair, it was trying for about 3 hours and then shut off. I don't think it's going to happen. Isn't there a check disc or fix disc I can do at the command prompt?

    Next on my list is to disassemble it and clean it out, maybe there is a bit of an airflow restriction, when I have it flat on a table it seems to shut down quicker than if I prop it up a bit where the air exhaust is located.

    I think it's the MBR that needs to be repaired.

    Anyway, everything besides Windows 8 boots in legacy mode, including Windows 8 installation discs. It's a pain in the ass to switch between them.
