Wow, this imploded for you lol.
"DMDE doesnt recognice my hard drive, neither the BIOS"
If the BIOS doesn't see it and if its an SSD type then try powering off and/or removing power to the drive for at least 10 seconds (maybe up to 1 hour; in worst case much longer)... and see if it shows up again after power on. SSD controllers can lock the drives for protection and when this happens they disappear from even the BIOS. Corruption can happen as well.
Thanks. This : "SSD controllers can lock the drives for protection and when this happens they disappear from even the BIOS" was important for me. All people say only "hardware issue" but never they explain the possible cause... the PSU was the issue (for me) but as the ssd disappear from bios then "they" say ssd / hard is the problem ...
