Norm,
I went thru your BIOS manual.
On the ADVANCED TAB: there is a choice SATA/IDE Configuration. In the list of 4 items, you should have bothl SATA drives listed
WD....AAKX
WD....AAKS
The printer is USB so it won't be on there, the TSST CD/DVD should also be there.
Then On the BOOT TAB: there is a choice Boot Options Priorities #1, #2, #3. #1 should be HHD, #2 should be CD/DVD, #3 should be USB. You can change the order of these items so it is correct.
There is also a choice Hard Drive BBS Priorities down a bit further. Click on it and please check the WD....AAKX as the first drive to boot from. That's the 6Gb/s drive. In most BIOS settings, you can check, or select the item. In cases where you have multiple HDDs on a computer, this tells the BIOS which to load the OS from.
See if that clears up the boot order problem.
Other thing that would be very very helpful, is if you could go to Disk Management (My Computer, right click Manage, Computer Management. Click Disk Management in the lower left area) and upload a screenshot of the Disk Management dialog box to post it here, so we can see if there is any problem in Drive recognition and labelling that might be interfering with proper loading.
