Upgraded to SSD, EFI partition still seems to be located on HDD

[SamSegal]

Hi,

I've upgraded my desktop PC from HDD to SSD a few years back. Then, I've added another, faster SSD in which the OS is currently installed in.
The problem: If I disconnect my HDD, the system won't boot - I'm reaching the "reboot and select proper boot device " message (The SSD does show up in BIOS, and in its the same one that also has a BOOT partition).

I would like to solve this issue so I may keep my new SSD one day and boot without having the old HDD connected.
Attaching a picture of partition manager:

My suspicion is that the SSD has BOOT, but not EFI? Could it be legacy? Or does it just indicate where Windows is installed?...
Anyhow, I'd like to move the EFI partition to the SSD and perhaps add a recovery partition on the SSD - without formatting any drive.
Or at least without formatting the SSD drive.

I'm also not sure what the other partition are in the HDD, but I've used a Windows command line command to verify they are not "required".

Yeah, you probably cloned only the Windows partition to the SDD instead of cloning the entire HDD i.e. all partitions.

Follow the steps given here and you should be good to go.

Oh wow, it's that easy!

I'll try this when I get back home and update.
If it works, I'll attempt to boot with the HDD disconnected, and if that works then I'll remove the EFI, and the rest of the unused partitions in the HDD.

Thanks for the quick reply! Will update soon.

Update: that worked, thanks for the help again.
