Super User Asked by tylyp on January 7, 2021
by now i’ve read a number of topics with similar questions but the answers vary heavily from running a single line of code in CMD to multiple-page instructions on creating a Windows fix USB stick and doing some other seemingly sophisticated stuff, so it’s quite unclear as to what actually needs to be done in my particular situation, which is as follows:
And this is where things got tricky: i thought that all i had to do now was to simply unplug the old HDD and have my 2 SSDs plugged in for the system to work – one SSD where i had my Win 10 system installed, and new SSD with the folders copied from the old HDD for storage purposes.
But Win 10 won’t load without the old HDD plugged in. At first I thought there was an issue in the BIOS boot settings, but it’s not the case.
Having read up on the topic i can guesstimate that because i originally didn’t unplug the HDD during the Win 10 installation onto the SSD, Windows has automatically placed the boot data from both Win 7 and Win 10 onto the old HDD.
The question is:
Is it possible to “move”/”copy” the loader or create a new loader for the existing Win 10 system to the SSD, without reinstalling Win 10, and remove the HDD from the system all together? If yes, then what are the step-by-step instructions?
Details from Disk manger:

If i “right-click” on the SSD “C” partition, the option to make it active is not greyed out
Details from diskpart:

Having received no meaningful feedback I continued to google the solution and was able to find one. I can't promise this same method will work for you, but it did for me in my situation. Credit to this Windows 7 forum: https://www.sevenforums.com/tutorials/209885-bootmgr-move-c-easybcd.html
Surprisingly the solution consisted of basically just 2 steps, involved no CMD line coding, no dealing with Windows Restoration tools, had a normal visual UI and was easy to follow along:
This made a copy of my existing EFI boot partition from my HDD to my SSD.
I then switched the PC off, unplugged the old HDD and successfully booted from the SSD.
One more step to clean things up:
As the partition was 100% copied from the HDD to the SSD, I noticed that during the boot it still gave me the option to load into either Win 10 (installed on the SSD) or Win 7 (installed on the now-removed HDD), so I went into EasyBCD and from the Edit Boot Menu just deleted the Win 7 boot option, so that it would load straight into Win 10.
I hope this helps to solve your issue if you're facing something similar, saving you the frustration of searching for the info and having a billion different solutions suggested all over the place.
