Here is my situation: I installed Windows 10 on one partition of a SSD. I tried to install another OS on the other partition and mistakenly ended up formatting the boot volume/system reserved volume on SSD. As a result I was not able to boot into Windows 10 anymore.

So I mounted another SATA drive on and installed Windows 10 on it. Using this installation, I followed instructions here (https://www.dell.com/support/article/us/en/19/sln300987/how-to-repair-the-efi-bootloader-on-a-gpt-hdd-for-windows-7-8-8-1-and-10-on-your-dell-pc?lang=en) to repair windows install and was able to successfully get my 'original windows 10' to show as a 2nd windows install on during boot time.

Now, I want to remove this temp SATA drive and be able to use the SSD ONLY as my windows instance, but I am not able to. If I remove it from boot option or try to boot directly into the SSD, I am unable to and I end up in the BIOS menu - which tells me that the System Reserved volume is on the temp SATA drive and I will need it always to be able to use my original windows..

I found instructions here (https://www.backup-utility.com/clone/move-system-reserved-partition-to-another-drive.html) to move the system reserved volume from one disk to another, but when I follow this,

  1. I see that the System Reserved volume on temp SATA drive is empty, but for a Recovery.txt file that is also empty (0 bytes).
  2. Moreover, I am not able to make the new system reserved volume I create on the SSD as 'active' - that option is greyed out.

How do I resolve these 2 issues. Thanks for the help.
