I wasn't able to fix this with the Windows Repair console, but wannabe1 suggested to parallel install Windows XP to access my data. That worked. Great!
Then, I wanted to burn my data on DVD's to have a backup, but
after I burned my first CD of data, while burning the second CD I got a blue screen. Restarted. Burned again... same thing happened.
Next, I try to reboot into the Windows0 OS and get a black screen saying "HDD hard error".
Tried F1 twice. Nothing.
Tried to reboot a third time. I am able to boot up again to the new Windows0.
What is going on?
I'll put my data on an external hard drive now, but what's the next step?
Do I have to get the hard drive checked or should I just try to wipe it clean and reformat?
