My Aspire A-515-54 is failing to boot. I have dedicated it to a Ubuntu 22.04 LTS machine. Windows has been deleted. My investigation so far tells me I have a mismatch in the /etc/fstab file which manages disk assembly on a Linux system. System also does not recognize a bootable thumb drive. One article suggested that I use the command /etc/fstab command to update the UUIDs. My computer has a file /etc/fstab with no contents. An empty file. Another article told me to try sudo e2fck -f -b 32768 -y /dev/sda. This command e2fck is "not found." I have access to the grub recovery commands and the initramfs commands. One additional thing, when I installed Ubuntu, the solid state hard drive was reformatted NTFS.

I fee there has to be a way to fix this computer. Anyone got suggestions? I don't have another computer to put the hard drive in, if I take it out of the Acer Aspire. HELP and thanks in advance.

Additional Info: I should also mention that the computer worked perfect for over a month. I did an update and (not sure about this) but I think I forgot to reboot after the upgrade. I was able to get a list of my partitions by the command cat /proc/partitions. The partitions are sda with 30720000 blocks, sda1 with 30686208 blocks and sda2 with 32768 blocks. Again, HELP and thanks in advance. RT01.
