If things get really grim, then I suggest you attempt to flash your bios and clean your hard drive using Command Prompt before you attempt this advanced method of update and recovery.
In order to do this, unplug the power cord from your computer—open your case—and remove the battery from the motherboard. Leave this removed for a few minutes. Press the power button to expel any lingering electricity in the system.
Put the battery back in, then press [DEL] to enter the bios upon start up. Navigate the menu and adjust the time, date, and then make sure that the [Boot Menu] option is enabled. You'll need this in order to boot from disc.
Save your settings and proceed to boot from your Windows installation disc. There in the opening menu, select the 'Repair your computer..' option.
Navigate this menu and find the Command Prompt option. Open that and when the CMD window pops up, enter the following commands in sequence.
diskpart
list volume
select volume #—enter the number listed as your hard drive
clean
This will totally wipe your hard drive clean, including your boot records. This can be used to solve extremely technical and comprehensive problems affecting your hard drive.
