simply enough, my computer wont load past the black windows loading screen, ( the one right before the main blue screen) i think its called the BOIS screen but i am probably wrong.

and i tried chkdsk /r (or however its spelled, and it didnt work right, it stopped at 50%, but upon reading many forums i heard it could take up to a week to finish, so i left it sit...


so here i am, OVER one month after i started chkdsk /r and it stayed at the 50% it stopped at....

i couldnt take it any longer so i shut it down. and now i still cant get past that screen. so is there any way i can fix my OS through a slave drive, or will i have to re-install it?

it might have been a virus (probably was) i was using comodo's free antivirus after all...
