Question Cloned ssd offline due to signature collision

[Zerplin]

I recently installed a ssd (gave it letter D) and cloned my old hdd to it with Samsung data migration software

Both are inside my PC as l want to keep hdd as storage/archive

I changed boot priority to wbm <ssd name>
But PC still boots from hdd ( task manager shows hdd under performance tab and ssd is offline)

When I check disc management it says ssd is offline due to signature conflict with an online disk. Other than that other partitions are "okay"

I've looked up some guides to change the signature, but i also like to know if this is likely the reason my cloned ssd won't boot ? Because i'm wondering why the problem isn't in the opposite direction ( booting from my ssd and having problems with my hdd being offline due to signature collision with my ssd)

( I run windows 10 )

Just solved it:

I changed the signature by right clicking the offline disk and selecting online under help ( this instantly resolved my problem and made the disk online again)

Rebooted and now both my ssd and hdd are online. And my PC booted from my ssd this time !
