Login screen black with flashing cursor

So I recently installed Windows X Yosemite transformation pack but didn't like it and had to uninstall. After uninstall it told me to press ok to restart . But when I restarted I couldn't see the logon screen. I tried moving my mouse pad and it would show the cursor but dissapear once movement stops, I've done some research and found this > https://support.microsoft.com/en-gb/kb/2756559
I believe this relates exactly to my issue but the workaround did not work. PLEASE HELP THIS IS REALLY URGENT D:

SYSTEM:
Windows 8.1
8gb ram
Nvidia gt 635m 2gb ddr3
Intel i5 3337u cpu with Intel HD 4000

Asus vivobook s550cm

Same thing in safe mode . I just see cursor appear and safe mode text in each corner

When I try reset PC it says
> unable to reset your PC. A required drive partition is missing

System restore
>to use system restore you must specify which windows installation to restore

Restart this computer, select an operating system and then select system restore
