Boot partition on the wrong disk

[Linus.User]

If there were two hard drives connected to the computer, one SSD for Windows 10 and the other HDD for data, and if the system was installed normally on the SSD, but the Windows 10 boot partition was installed on the HDD instead of on the SSD, would it be possible to move it? It's best to prevent such situations and disconnect the HDD during Windows installation, but what if it already happened?

 

Where would the boot partition be created if there was only 1 disk already partitioned. What if Windows XP was already installed on the first C: partition and the second D: partition was prepared for Windows 10 and there was no unallocated space to create a boot partition? Would Windows 10 then use the C: partition from Windows XP as the system partition and add the boot files to it?

For efi boot partition, Best to create a new efi boot partition on the preferred drive.

Best instructions I found for this

XP only supports mbr boot. It does not support EFI, so you are most likely booting with CSM enabled? In that case Win10 will write to the MBR and not create a separate efi boot partition.
