messed up my work station because of booting Ubuntu on a guest SSD

If you want to have a clear understanding and a nice explanation of BIOS boot-ing, UEFI boot-ing, etc…, Highly recommend this article –

UEFI boot: how does that actually work, then?

I have managed to mess up my work station, only because I have connected an SSD to the desktop and installed Ubuntu on that guest SSD,

So after installing Ubuntu on the guest SSD, and removing it from my workstation… DESPAIR! – my Linux Mint did not boot!!? – I panicked and I just wanted things to work the way they were
So I looked for a quick solution, Boot Repair which with just a few to solve my problem… of course it didn’t work and it might’ve broken things even worse…

Disk Partitions, Boot loader

I don’t have a through understanding of disk partitions, file systems, boot loaders, etc…

And I am trying to understand things.

– so I have a newly bought disk/SSD. It is not partitioned
– before installing an OS/Linux, I need to partition it

So we have:
1. Partition. Which is a container with a file system
2. A boot loader for the disk

 

Always keep in mind the distinction between

• a partition (a simple data structure that defines the start and end point of a chunk of disk space, typically along with other things like a type code) and
• a filesystem (a more complex data structure that’s held within a partition or another container, such as an LVM’s logical volume). If you don’t already fully understand this distinction, stop now and research it.
