From shutdown, when I try to boot this windows 7 64-bit machine, eventually the Reboot and select proper boot device or insert boot media...... message appears. First there is attachment 1, then attachment 2. After hitting ctl-alt-del, then tapping F10 to get to bios (ver 6.02, attachment 3) , I arrow over to Boot, down to 1st Boot Device, enter,select HDD group, enter. Then F10 to save and it boots. Now, restart will always reboot, but not ever after shutdown.
Things I've tried: Replaced CMOS battery, Restored to original configuration, bootrec.exe (fixmbr and fixboot), repair startup, etc. Any assistance will be greatly appreciated. It appears that it's trying to go to a network boot 1st but not sure why.
