UEFI Boot Priority for new SSD

Hey guys,

I finally got my SSD to work properly but currently I have W8 installed on both the SSD and my old HDD. When I take the HDD out, the computer boots to the SSD no problems, but when the HDD is in, it always boots off the HDD.

I've gone into BIOS and had a look around and there were essentially two options:

Legacy and UEFI (Default)

When I choose UEFI, there are only two options for booting. Windows Boot Manager and Network boot. When I put Windows Boot Manager on top, it automatically boots to the HDD with no option to set the SSD as boot priority 1.

When I choose Legacy, it gives me a lot more options including USB, CD Drive, HDD and SSD. However, if I choose the legacy boot mode, it will give the error message "Operating system not found" no matter what.

I've read around about how to change boot options and all the articles just say to go into BIOS and change boot priorities, but I don't see how it can work for me.

Anyone have an idea?


Note: I chose MBR instead of GPT when initializing the SSD for the first time but I didn't think that would be a problem.

  1. If you don't need OS on both the drives, then format the HDD with a bootable media. Remember to unplug the SSD prior formatting. The problem will be solved.
  2. I didn't want to do that for a few reasons:

    I tested again and the computer no longer boots with just the SSD plugged in. It keeps going back to the boot menu when I select the SSD to boot off.

    The HDD still has all my data and installed programs. I wanted to simply install the OS on the SSD, boot off that and keep the HDD to access programs I do not use often.

    Windows OS should be in native mode in BIOS, for SSD it should be AHCI, and in legacy mode.
