How do i reboot my

disguard the above soloution, that only works if you have a recovery partition and you have a recovery disk!!! what you need to do is get into the bios, try these keys until one works: try F2 first, if that doesn't work try DEL or Esc, when you get into the bios you need to change the boot option to boot from cd as first boot device, press F10 and select ok, y or yes, make sure the disk is in the drive because the system will reboot and you will be able to recover the system, repeat the steps i gave you to change the boot order back to the hard drive after you have completed your recovery

good luck

Is this a trick question? Or are you serious? You reboot by shuting it off and turning it back on. or using the ctrl,alt, and delete buttons at the same time.
You can try this too.
Using the F8 Method

1. Restart your computer.
2. When the computer starts you will see your computer's hardware being listed. When you see this information start to gently tap the F8 key repeatedly until you are presented with the Windows Vista Advanced Boot Options.
3. Select the Safe Mode option using the arrow keys.
4. Then press the enter key on your keyboard to boot into Vista Safe Mode.
5. When Windows starts you will be at a typical logon screen. Logon to your computer and Vista will enter Safe mode.
6. Do whatever tasks you require, and when you are done, reboot to go back into normal mode.
