I have installed Ubuntu on an external SSD. So now I have an internal SSD with Windows on it and an external SSD with Ubuntu, which is meant to use on different PCs.

When I now boot my PC, I can select if I'd like to boot Windows or Ubuntu. My problem: I can only select that, if I have plugged in my Ubuntu-SSD - but that wasn't the idea of that. I also do not see the Windows-SSD in the BIOS anymore, only Ubuntu. I wanted my Windows to boot normally and if I plug in Ubuntu I can select that option.

Can it have something to do with that, that I did not unplug the Windows-SSD when installing Ubuntu on the other one?

Thank you!

Most likely your boot partition is also installed to the external drive alongside Ubuntu. Try to reinstall GRUB (with Boot Repair or something similar) to the drive with Windows. That will help to achieve what you want.
