How to skip filesystem checks during boot
Solution 1:
Removing Disk Check From 20.04 Boot
The command line option fsck.mode=skip can be used to skip the disk check when booting Ubuntu 20.04.
The line Checking disks: 0% complete may still come up but fsck will not be run, nor will boot time be increased.
Add fsck.mode=skip to the linux line in grub.cfg just before quiet splash
It is recommended to add the command to grub.cfg by editing /etc/default/grub thus: GRUB_CMDLINE_LINUX_DEFAULT="fsck.mode=skip quiet splash" and then run sudo update-grub.
I have had this problem with a Live USB but not with an installed system.
