I have Vista Ultimate 64bit. The screen shows "reboot & select proper boot device or insert boot device in selected boot device & press a key. Does that mean I will have reinstall Vista? Which means I will loose all my data. I do have most of the info backed up. We had a power outage for no apparent reason. Probably a squirrel or something like that. It is on a APC battery, which closes down the computer after a period of time. Thanks in advance John
