Booting From SSD with different OS

[sam.trilling]

Hello everyone,

Just downloaded and installed Windows 10 on my SSD (using an external hard drive). During this process I unplugged the SATA cable connected to my HDD (saw online that it was recommended) that has Windows 7 installed.

Now every time I try to start my computer, Windows 7 boots instead of Windows 10. I rearranged the boot sequence in Windows 7 to see if that would fix my problem, but it didn't.

(Also, in attempting to solve these issues I reformatted my external hard drive which I THOUGHT would just wipe the Windows 10 info but actually cleared everything... oh well)

I would love some guidance on how I can boot Windows 10 consistently from my SSD, delete Windows 7 from my HDD, and any other helpful information you might be able to provide (before I cry).

Thanks!

Go into your bios and set the SSD as the primary boot device.

When I'm in bios, I see Boot List Option (set to Legacy), all of the potential boot options (all checked), and the ordered boot sequence.

When I rearrange the sequence so the SSD is at the top, press apply and exit it resets itself back to the harddrive priority.

It sounds like the bios isn't finding anythig to boot from on the SSD and reverting back to the HDD. As a test, unplug the HDD again and see if it boots from the SSD now.
