After Reboot, I choose the Recovery Console, like you said; then I choose 1 and press ENTER
After that appears C:>WINDOWS not C:> like you said
so I typped:
attrib -s -r -h "C:\WINDOWS\SYSTEM32\gnhhmu.sys" and press enter it said it is an unknown command... I think I made a mistake... I don't know the sense of "return" maybe... BACKSPACE, or... ESC?
I don't know how to typped the rest of the lines... I don't know how to made this... please help!
I know it is a stupid mistake from me, but I don't know to made this... you can explain again? and why told me that was an unknown command? Oh...
