My Specs:
Lenovo Think-Pad-L380
SSD: Samsung MZVLW256HEHP-000L7
Hello all,
I wanted to re-install Ubuntu and switched to the Version 20.04.3 from 18.04. I created a bootable USB-Stick with Rufus. In the installation menue from Ubuntu I choosed "Replace 18.04 and ... ". After the installation was finished with no error I restarted my Computer and ended up in a boot-loop where the Lenovo Logo flashes, in the right corner stands "Reset System" in an infinite loop.
Before the re-install of Ubuntu I used dual-boot. However I can still wipe the disk and install Windows 10 and everything works just fine, but if I try to install Ubuntu alongside Windows 10 I end up with the same issue all over again.
My thoughts are that maybe the SSD is corrupt and the old grub booter from Ubuntu is still on the SSD, so the BIOS don't know where to boot and tries to restart. I already tried to erease the SSD as good as I can at Windows with EaseUS. But that didn't help at all. Besided that I tried every setting in the BIOS (Secure Boot, Boot only from legacy and so on), but that didn't help either. Interesting enough I tried to install Ubuntu and selected in the installation mode "erase disk and install". Still no success.
Does anyone run in the same problem or maybe someone has an idea I can try? Thank you in advance.
EDIT: I just tried the solution from this thread. But it still won't work Infinite boot loop - Ubuntu 18.04 (System Boot Order not Found) as well as boot-repair not fixing boot issues
I also removed the Ubuntu OS with OS-Uninstaller. There shouldnt be any OS on the system right now, but it will still says "Reset System" and reboot-loop
