I was working with a CAD program in Windows 8, and when I went to save a file, the computer locked up. After a while, I rebooted the computer, only to find that Windows no longer boots.
I have a dual-boot system between Windows 8 and Ubuntu 13.10, both on the same HDD. I can access Ubuntu easily, but most of the Windows files are write protected due to the presence of hiberfil.sys (even though I disabled hibernation a few days ago).
I have tried the following:
-BIOS secure boot
-Recovery media boot
I am pretty confident that this is a hard drive error, but I cannot boot to CMD to run CHKDSK.
Detailed error description: The machine boots to either the GRUB menu or the VAIO system setup menu, depending on which boot mode I'm in. After selecting a boot option, it proceeds to a black splash screen with "VAIO" across the screen. Every other normal boot, the text "Preparing for auto-repair" appears. Then, the screen goes black, and a Blue Screen pops up with the mentioned error after a seemingly random (sometimes very long) time interval.
Computer specs: Win8/Ubuntu13.10 x86-64 with Intel i9 2.4GHz processor, 8GB ram, iTB HDD, 24GB SSD, Sony VAIO SVT15115CXS.
Specifically, I'm looking for a way to run CHKDSK, or mark that it should be run on startup, through Ubuntu. I think this may fix my problem, but I don't know where to start...
