Vista Boot Sector

[SpyCatcher]

For some reason Vista U will not warm reboot on its own unless I shut down the system, restart from that point.

I have done the following to fix /repair:

Run Start up recovery.

Load the vista installation disc, repair, command prompt "bootrec.exe /fixmbr /fixboot and /rebuildbcd

I have check and reset the BIOS

Still not working, any help would be appreciated.

Thank you

What happens when you have it do a restart? Does the computer turn off?

I would imagine that if this is indeed an issue with the boot sector, it wouldn't matter how the computer was booting up.
