Starting the recovery from power up
If Windows Vista cannot open and if the Recovery partition on the hard disk drive is functioning properly, you can perform a System Recovery by performing the following procedure:
1) Turn off the computer.
2) Disconnect all connected devices (such as the Personal Media Drive, USB drives, printer, and fax), remove media from drives, and remove any recently added internal hardware. Do not disconnect the monitor, keyboard, mouse, and power cord.
3) Turn on the computer.
4) Do one of the following actions depending on how Windows Vista was installed:
If Windows Vista came pre-installed on your computer, press the
F11 key repeatedly when the first screen opens (the logo screen), until Recovery Manager program opens on the screen.
If Recovery Manager does not open, a set of recovery discs is needed to perform a System Recovery. Follow the instructions listed in Starting the recovery from recovery discs .
