I have a Lenovo Carbon X1 Gen 9 and I have had it for a few years and it has gone through several upgrades. But now after reboot it only shows Memtest86 and there doesn't seem to be anything to boot into! Has anyone encounter this?
At some point during the upgrade I got a warning (a prompt with yes/no) saying that the upgrade is trying to remove currently used kernel and I said not to remove the kernel (thinking I can always upgrade it afterward). Now the laptop is dead. Any help is appreciated.
"everything" was working perfectly fine before upgrade. Now I regret it so badly. The machine can only get into Memtest86 and nothing else. It keeps running it over and over again.
Thanks
OK, I got one step ahead: the problem is that grub launches Memtest86 because it cannot find the kernel. Now why it cannot find the kernel and how to restore it I am still trying. If you know how to fix this situation, or faced the same situation please comment.
