I know I can run two hard drives in my system. My question is, I have two hard drives that both have Windows 10 installed. I need to keep my 2.5 SATA HDD because of a glitch with Quickbooks and them not providing me a code to reactivate the software after a drive clone to a PCIe NVMe SSD.

I know I can go into Bios and set boot priority. I looked yesterday and IIRC it's set to UEFI not legacy. I don't have the SATA HDD installed right now so obviously the only HD listed was the new SSD. I don't want to mess anything up by installing the SATA and causing any sort or boot issue. I want to be able to access the SATA HD to run quickbooks. Is this possible without booting from the SATA HD? I'm thinking I should be able to access QB with the SATA HD acting as a storage device.

So what, if any, steps do I need to take to be able to access the old HD? I considered just plugging it into a usb port and using it as an external drive but that seems like a pain.
