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.
UpdateI saved myself by creating an installable Ubuntu 24.04 on a USB stick and then copying that kernel onto my machine. I managed to load the kernel from the distro on USB stick, chrooted and install a kernel from repo. Then rebooted the machine. Then Ubuntu 24.04 loaded. But, still a "lot" of stuff was missing. It seems the installer performs post-install steps that I had to do manually, such as installing desktop manager, etc. Finally I am running 24.04.1 but who knows what's missing from 20.04 I was running. I install missing packages on need basis now.
I have been through at least 3 distro upgrades as far as I remember and this was the first time the upgrade nuked my kernel and I was left dangling. I am just saying. It's possible that there was something wrong with my setup but I doubt it.
