My Lenovo Thinkpad running Ubuntu 20.04 has started to take forever to boot. I read that it might be due to it trying for a long time to mount a partition that no longer exists in /etc/fstab but I'm not sure how I can verify it. My fstab currently looks like this (uncommented lines only):
UUID=31fad817-9f1c-4405-a552-8562c0e51c7d / ext4 errors=remount-ro 0 1UUID=E244-61F0 /boot/efi vfat umask=0077 0 1/swapfile
How can I verify if this is correct? Is there anything else I can try to speed up the boot?
