Hello everyone, I hope someone can help me out as I can't find any solution to this problem. I have read some posts on this forums that suggests to use chdisk, run in low resolution, repair the installation but none of this has worked for me. When I start the laptop (toshiba satellite) it runs and boot logo comes up, after that a black screen with a cursor. Using one of the option that stop windows from restarting during crash I seen that the blue screen says "unmountable boot volume" I have windows 7 dvd which I used, it says to press any key to contnue, once done nothing happens, a boot logo comes again and the black screen with the cursor. I hope someone can help, thank you.
