Double bootable drive setup, one doesn't boot

[laminutederire]

Hi there!

I upgraded recently my laptop HDD to a samsung SSD. It boots well and everything,  basically everything is good.

When I connect the old drive, it works fine (the administrator rights to be updated aside of course), it is recognized and I can access it. To retrieve some licenses I want to try to boot again with it, do a few manipulation to export those licenses so that I can use those on the new drive.

Issue is that it won't boot, it either BSOD (error inaccessible_boot_device) or it crashes at the bios level and tells me I need to repair the bootable part of windows on that drive. I repaired it without issues, but it still won't boot with the previously mentioned  BSOD.

I connected it with an external case which takes sata drives to be connected with USB 2.0 or 3.0.

Can it be that it can't boot as external drive, or is windows on that drive fucked up by a manipulation I did when swapping drives?

I'll swap them again tonight to see if it boots when place directly as internal drive. I hope it will indeed boot.

We need more info to proceed

 

If your board UEFI or BIOS? Were you booting your old drive in UEFI mode or legacy mode? Did you change modes when you installed the new SSD? What did you manipulate when you swapped the drives over exactly?

 

Also you should not have tried a boot repair on the drive until you were 100% sure the UEFI/BIOS in your system was setup correctly, you might had inadvertently destroyed any chance you had of getting the drive to boot again.

It boots in UEFI mode, both of them actually. Didn't change any settibgs in the bios to install windows 10 on the SSD and then boot correctly. 

What I manipulated : I install the second drive with an external case, in the windows version the SSD boots.

I wonder if mounting it like that could have overwritten the boot infos.

Yeah... well it's done and that's why I'm afraid of...

Can it be because the external case in which it goes from SATA III interface to USB 3.0 is doing something that prevent it from booting?
