No boot from my SATA drive?

I had a SATA SSD running updated Win 10 on an old laptop, SATA set in BIOS to AHCI. It was cloned earlier from an earlier HDD.
I installed it now in an Asus P5440FA that also has a NVMe running Win 11, after upgrade. But I cannot make it boot to the SATA operating system.
The drive does show in Win 11 and in the UEFI, but not in the UEFI's Boot options, nor in the Add Boot Option. I tried disabling Secure Boot, and also changing SATA from Intel's one to AHCI, I also tried taking out the NVMe. None of that helped.
Is it just about fixing the boot with a Windows Setup drive? Or is it something else?

We need to see a screenshot of disk management with both drives connected. Please follow all the instructions in the tutorial:

Attached. Translated one partition for you (could it be a problem?).

Interestingly, after reconnecting the NVMe, and restoring UEFI options, it would not boot – gave BSOD for inaccessible boot drive. Only worked when I changed the boot drive from the one it automatically added to the one that I manually added earlier (and ended up booting the same then).

What happened that the system reserved partition was labeled D:?

Not sure if that's what you need, or where is CSM, but here:

No more BSOD now. Maybe one different boot or x number of restarts fixed it.

msconfig added

The problem is that you are booting dus 0 in legacy BIOS (CSM) mode and booting disk 1 in UEFI mode.

I just want to boot the old drive. Can I do that? How?

bcdboot E:\Windows /d /addlast

Thanks. I see now that it's a 32bit Windows 10, and no winload.efi, so no way out?

Did you try the command I gave you? And the other way out is to convert disk 0 to GPT and UEFI booting:
Convert Windows 10 from Legacy BIOS to UEFI without Data Loss

Also, if your BIOS has a setting to enable CSM and/or legacy BIOS booting, you could boot disk 0 in CSM mode.
