Cloned 1909 with dual boot won't work as a secondary OS drive to 2004.

I wanted to use windows 7 as a dual boot but I forgot to remove all drives except for the one I'm installing 2004 to and it got corrupted. It was a feat to get the correct modded drivers installed in the first instance.

I have my primary OS which has a boot menu of normal and safe mode.

The seconday OS won't boot. I tried using EasyBCD on it didn't help. I've tried paragon hard driver manager 17 recover (win pe & unbutu). I've tried macrium reflect which although would let me restore from a backup apparantly & I can restore form the system restore points.

On the windows 10 install media I don't have a recovery option.

Is there a way to fix this? Initially I just want to boot, no options. I'm on version 2004 but the OS I'm trying to repair is 1909. I've already defraged it.

Can you post a screenshot from disk management so we can show all details. You say cloned what was cloned as if there is a cloned disk it can have the same disk signature as the boot drive. The new installation maybe uefi

You're right P: is cloned from previous 1909 C: drive install which was dual boot 1909 & win 7 pro (modded drivers for X570). They are all GPT formatted (just checked). I was booting in CSM now in UEFI exclusive. I need to check if it makes any difference for P:.
