The BIOS can no longer find the notebook's built-in hard drive! What can i do?
Linux mint 20 should be on the hard drive.
Check the removed hard disk with another computer whether it is recognized. If not, it is defective. Possibly. Is it just not tight enough in the slot, so that a few pins may not have any contact.
whether or which operating system is installed is irrelevant in the bios. The POST procedure only checks whether all hardware is working properly.
Maybe something is wrong with the contacts. Remove them, put them back in properly and then look again in the BIOS.
It does not work. It is built into the laptop
I can't take it out, it's fixed in the laptop!
Which notebook is that?
Which laptop is that? It is unusual that it should not be interchangeable!
How does it get in there?
In a comment you write that you can't expand it?
Don't let Microsoft fool you. They refer to each partition as a drive. But then these are not drives, i.e. Hard drives.
The BIOS only recognizes hard disks and does not list partitions.
It's a little different in the UEFI. The UEFI software also accesses a FAT32 partition.
One from medion which exactly I don't know. I didn't find any
