Summarize the following:
If you feel comfortable handling computer hardware and have another computer available, you can have full access to the information by connecting the hard disk to another computer. This section assumes that you have some basic knowledge of computer hardware. Pull out the power, monitor cables, PS/2 and USB devices, the speakers, etc. All cables and external devices must be removed.    Be sure to set the jumper to the correct setting, for now you may want to set it to "slave". Copy the information you want to save.

Summary:
Be ready. Shut down your computer and disconnect everything. Open up the computer case. Locate the hard disk. Disconnect the power and IDE/Serial ATA cables. Either mount the drive to another computer or use an IDE/Serial ATA to USB  device. Boot up the second computer and log in. Put the drive back in the original computer and wipe everything, then reinstall Windows as usual.
