Can't boot from my old SSD with a Carry Disk

Hi. I was looking everywhere about this but I don't seem to find anything remotely related.

I'm trying to boot from a SSD that was my previous default storage and where I had my OS installed using a carry disk. I changed my laptop and I would like to use this previous SSD through a carry disk but it does not show as a bootable option. I tried using an older HDD with the carry disk and could run windows perfectly there, and also another OS that I had installed in a pen drive.

The SSD in question is detected and I can see through the files once my laptop is on and running in its predetermined OS, but it's not detected as a bootable option from the BIOS.

Any ideas why could this be?

My laptop is an Ideapad Gaming 3 15IAH7

BIOS version JMCN36WW(V3.02)
