I have a Dell desktop running Windows Vista Basic, I turn on the machine and all I get is Enter Password with a black screen. I don't know why I am getting this so I tried turning it on and entering F2 for setup and it says the same thing enter password. I opened this and removed the password jumper then turn it back on and still getting the same thing enter password on black screen. I thought removing the jumper would reset the password and allow me to start vista and set a new password. What can I do now to start Vista? I have data to save on this hard drive.
Try to open the chassis, take the CMOS battery out for few minutes (or hours...), put it back in and try again.
If it doesn't work, you can also check for jumpers on the motherboard... Please check your motherboard model and check online for some info about jumpers... If necessary
