New windows 10 installtion on New SSD - wont boot unless old SSD present

It seems you installed Windows while the both SSDs were connected. This would have caused your current problem. Maybe it is sufficient to do this:

1. Launch the Disk Manager.
2. Right-click drive C:, then mark it as "active".
3. Shut down Windows
4. Open the BIOS and tell it that the new SSD is the primary boot device.
5. Disconnect the old SSD.
6. Boot up normally.

If this does not work then you might have to do this:

1. Disconnect the old SSD.
2. Re-install Windows on the new SSD, using the Media Creation Tool.

 

Adding an old SSD to new computer

When I got my new computer, I also got another SSD, so now that I am adding the old SSD in addition to my new one and HDD I am not sure what to do. Before I added my SSD from my old one, I reinstalled Windows 10 on it. I do not want to remove it since it
cost me money, so I am keeping it as a backup, however when I open file explorer, I see 4 disks; Local Disk (C, HDD (D, System Reserved (E, and Local Disk (E. The last two have only appeared after I have added the old SSD.

My problem is that I would like to use my old disk for games, yet want to keep another copy of Windows 10. Additionally I don't fully understand why the System Reserved disk shows up and would not like to see it, do you know what I can do?

 

New Windows 10 Installation on new SSD made old Windows 10 on Old SSD Unbootable

It looks like the new install (if you installed with both SSDs connected has updated the other partitions on Disk 1. This is why the old SSD won't boot and the new one won't boot on its own.

If you disconnect the old SSD then the new one won't boot, correct?

If you remove the new SSD can you repair the old SSD from the USB install media.

Then connect the new SSD and disconnect the old SSD and clean install again on the new SSD so it has its own EFI and recovery partitions.
