I replaced my old laptop drive which was win7 and ubuntu dual boot with an SSD.

Now I connected the old drive through a USB adapter and I want to boot from it.

But this comes up:

unknown filesystem
grub rescue>

As i need the programs from old drive I have to boot from it time to time and I don't want to install those software on the new drive. It takes so time to exchange the drives so I want to boot from USB.

how can I fix this?
