Win 7 Pro 64 Bit BOOT problem

I didn't make further progress so I finally "gave up" and Restored the drive from the 9-2-2014 Backup plus updated data for the few days so to not be missing any Email data.

I certainly appreciate the time and effort by all that helped.

I will now re-connect and re-assemble all items, replace the Computer Cover, and move the second Monitor back in place since I can't be working on this next week.

Thanks again to ALL....

I'm trying to learn from your experience. When both drives were connected via SATA cables to your motherboard, was the 07-28 drive connected to a lower numbered SATA port? IOW, was the 07-28 drive connected to SATA-0 port while your normal boot drive was connected to a SATA-1 port? If so, that might explain why it booted from the 07-28 drive first.

I actually don't know the connection "order" (from memory), however I can check. The BIOS Setup should control which Drive is used to Boot from -- Plus, I also (use added precaution) and also selected the F8 screen and specifically selected the normal drive to Boot. Both areas were selected to use the Normal Drive -- but instead it used the 07-28 Drive to Boot.

I've had problems booting from the drive selected in the BIOS boot order. IOW, in the BIOS I selected booting from a boot CD in the optical drive as boot-1, with booting from the system HDD as boot-2. But the PC would boot from the system HDD regardless.

This may not be what could have caused the above to happen - but possible. On my computer, my Boot choice is set first to use the 1.44 Floppy, next the CD Drive, and last the desired Hard Drive. If I want to boot from the CD Drive' and have a Bootable CD in that drive, (and don't also use the F8 to stop and select the CD) for my computer (evidently yours uses F12) -- then there as a VERY short time pause asking to press a key to Boot from CD. If that request (I use space key stroke) key is not done VERY quick, it will continue and Boot from the Hard Drive -- NOT the CD.

My computer is a 2007 vintage and is much slower than current Models. I can only assume the pause time for newer/faster machines is very short and would be easy to miss even seeing the message on the screen.

If the F8 key (your F12) is in use, the machine will pause and wait to select the desired device to use to Boot (using the CD) and then it will boot from the CD and not the hard Drive.

Note: In case you wonder, I have the 1.44 Floppy for several special uses relating to some licensed programs and other needs for this system. One was for System Backup software until a few months ago I changed to using Macrium software for System Backups.ell Computersin my case and

I had to use the F12 boot order screen and change to legacy boot in order to boot from the optical drive. This is different from your problem but it does show that changing the boot order in the BIOS does not guarantee booting from the selected drive in the BIOS.

Checking the connection order of your SATA drives connected to your motherboard might shed some light on why your PC booted from the wrong HDD.

NOTE: Both the Internal Hard Drives plus the Removable Racks have the same SATA connections that I have been using since this computer was built (Assembled) in late 2007. This computer also has one CD-RW drive, 1 DVD-RW, plus 2 EIDE Drives (for compatibility with older machines) -- one is internal and one uses a Removable Hard Drive tray.
