Booting Ubuntu takes ages with system file check

I have been using ubuntu 20.04 now. Every time I try to boot into Ubuntu, it starts with a filesystem check (I'm not sure if that's what it is), as in in the image attached, which takes atleast 5-6 minutes before the user login appears. Earlier I used to dual boot with windows 10, I assumed that could be the problem, but I tried installing only ubuntu and the problem still persists. I also tried reinstalling the grub but that too didn't help. I have got all hardware requirements satisfied. This behaviour wasn't there when I first installed Ubuntu 20.04, but it appeared after installing for the 3rd time. I think there's a bug introduced with an update.

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.
