Hi all, I just finished updating Windows 7 Ultimate on my studio computer (labeled studio in my systems if you wish to see all specs) and when I went to reboot it, it displayed the error message "PLEASE REBOOT AND SELECT PROPER BOOT DEVICE". So immediately I thought I must have the boot order wrong or the hard disc set to RAID or something. What I've done so far: 1. Tried to play with BIOS settings and SATA connections in every possible configuration. - NO RESULT 2. Tried to boot from Win 7 disc in order to repair. - got same message even when hard disc disconnected 3. Took out one stick of RAM and tried both in both slots. - NO RESULT 4. Checked all cabling and recabled entire system from ground up. - NO RESULT 5. Swapped out motherboard with a completely different brand new motherboard (the MSi 785GTM-E45). - NO RESULT 6. Repeated steps 1-4 with new motherboard. - NO RESULT 7. Checked hard drive multiple times and even booted from it attached to my MAIN computer's motherboard. - Hard drive totally operational, no result for studio computer I need serious help on this one. If anyone has any advice that I have not tried, please, please, please help! It is an older hard drive, but has only been used with Win 7.
