I created a efi partition now, and a bios protected area partition.
I installed another system, just to boot to grub, and it worked fine.
When I boot the previous system it says: no such device: SOME_UUID
(uuid of the boot partition)
/vmlinuz-linux not found
Also I encountered the problem that I have no internet.
So I can't reinstall the kernel.
What I saw is that I have two interfaces, eno2np1 and eno1np0, I set
my ip address in /etc/network/interfaces as the previous one, but I
can't reach my dns server.
I always says: Temporary failure in name resolution.
I also can't install any dns tools like systemd-resolved, because it
doesnt seem to be installed.
I set my domain name, hostname, but nothing works. I tried to dhcpcd
both interfaces, but It gives me some random Ip address which I havent
even configured. Like 169.255.255.255 or something.
AAAHHHH.
