Dearest Lubuntu friends,
I experienced a boot issue today. I am using 22.04.3 LTS (Jammy Jellyfish) on a ~2017 Dell XPS intel Core i7 vPro 7th Gen laptop. The notice was fast but it appeared to mention kernel panic not syncing.
The Dell Bios tool took over and identified errors and wanted me to enter a recovery mode. As I did not want to revert to Windows, I got a hold of a 22.04.3 LTS (Jammy Jellyfish) SD card instance and was able to boot the computer selecting “Try Lubuntu.” My plan was to get into the hard drive that way to try and fix the problem.
However, when I try to access the drive “LITEONIT LGT-256M6G,” I receive error messages “Can’t mount file” “The path is not mounted.”
Listing partitions shows sda without a mountpoint:
lubuntu@lubuntu:~$ lsblk -o NAME,FSTYPE,LABEL,SIZE,MOUNTPOINT
NAME FSTYPE LABEL SIZE MOUNTPOINT
loop0 squashfs 2.4G /rofs
loop1 squashfs 163.3M /snap/firefox/1635

Following instructions to try and mount the drive manually produces the following:
lubuntu@lubuntu:~$ sudo mkdir /mnt/drive256
lubuntu@lubuntu:~$ sudo mount -t auto -v /dev/sda /mnt/drive256
NTFS signature is missing.
Failed to mount ‘/dev/sda’: Invalid argument
The device ‘/dev/sda’ doesn’t seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

Specifying a partition number produces these results:
lubuntu@lubuntu:~$ sudo mount -t auto -v /dev/sda1 /mnt/drive256
mount: /mnt/drive256: special device /dev/sda1 does not exist.
lubuntu@lubuntu:~$ sudo mount -t auto -v /dev/sda2 /mnt/drive256
mount: /mnt/drive256: special device /dev/sda2 does not exist.
lubuntu@lubuntu:~$ sudo mount -t auto -v /dev/sda3 /mnt/drive256
mount: /mnt/drive256: special device /dev/sda3 does not exist.
lubuntu@lubuntu:~$ sudo mount -t auto -v /dev/sda4 /mnt/drive256
mount: /mnt/drive256: special device /dev/sda4 does not exist.
Here is a screenshot of KDE Partition manager for sda:
So, I suppose my question is either how can I actually access this drive? And barring that, how can I get the data off it?
I would of course be bummed if the drive cannot be restored, but it would be less than ideal to not be able to get the data on it. Some things are backed up, but of course not everything!
Thank y’all so much in advance for your help!
All the best,
thankyouguitar
I ran boot-repair at some point and it was suggested that I post this output to the forum to ask for help:
