I am booting Ubuntu from USB. Initially it checks disk for about five minutes. Is this step necessary? Is there any problem if press ctr + C?

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 /boot/grub/grub.cfg just before quiet splash for GRUB boot or in /isolinux/txt.cfg for Syslinux boot.

`toram`

For those people who think a filesystem check every boot is a good idea.

It takes a little longer to boot toram, but the file system check takes about three seconds rather than three minutes, (about sixty times as fast), and the system should run faster once booted.

Add the command toram to /boot/grub/grub.cfg or /isolinux/txt.cfg similar to above, or to syslinux.cfg for UNetbootin.
