Windows 7: Windows 7 UEFI/bootmanager stops booting after 2nd HDD installed

Windows 7 UEFI/bootmanager stops booting after 2nd HDD installed

New Windows 7 install on a computer with only one hard drive. However, I now have another HDD with data on it that I need to plug into my SATA port on my motherboard. Once I plug this other hard drive into the motherboard I am no longer able to boot into windows. When it boots it now takes me to a black screen saying that it can not find the boot device. Once I unplug the new HDD it boots just fine. I'm assuming this has to do with my Windows 7 HDD being given a different ID from Disk 0 to Disk 1. an easy fix would be to change the order of where my Hard Drives are plugged into the SATA ports on the motherboard. The issue is that I can not do this because the Windows 7 Disk is a SATA III 6Gb/s so i need/want it to be installed on the SATA III 6Gb/s Ports and the 2nd Disk is a SATA III 3 Gb/s drive so I can't install it on the 6 Gb/s ports on the motherboard. On my Motherboard it seems to order the SATA III 3Gb/s drives first on the Drive order and the SATA III 6Gb/s at the end of the disk ordering. So, right now what I believe I need to do is Change my EFI/bootloader to point to the new Drive 1 location instead of the old Drive 0 location. Normally this isn't hard with MBR because you would just go to Boot.ini and change it there with no problem. However, I am unsure how to do that with EFI boot stuff and I have not found the specific solution to do this through searching the internet yet.

If changing the EFI to point to Disk 1 instead of Disk 0 is the answer. How would I go about doing this? If it isn't the answer does anyone have the answer?

Have you tried booting into safe mode to see if you can get to windows or you could also try to select the proper boot selection before booting to windiows via boot media selector on my computer when i start computer i have to hit f8 repetedly until it ask me what device i want to boot. These are not solutions just something to try to see if windows will boot with other harddrive at all. Also did other hard drive have a copy of windows installed on it or was it purely a data drive

Boot into BIOS setup to set the Win7 drive as Primary hard drive and as first device set to boot in the Boot Priority order.

Sometimes you must do this by choosing which hard drive is Primary under Storage drives, other times you will have your choice of all installed hard drives in the Boot Priority order to set whichever you want first before the others.

Did the data hard drive ever have an OS on it, and if so was it correctly deleted by deleting its partition and not just files?
