Check the current filesystem status and how they are mounted on your computer.
$ mount
/dev/nvme0n1p2 on / type ext4 (rw,relatime,errors=remount-ro)
/dev/nvme0n1p1 on /boot/efi type vfat (rw,relatime,fmask=0077,dmask=0077,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)
sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,relatime)
proc on /proc type proc (rw,nosuid,nodev,noexec,relatime)
We can read this as the device /dev/nvme0n1p2
is mounted on a mount point /
$ lsblk

Multiple "loopX" partitions is because of "snaps," which is the Canonical's universal package management system. But for now, you can just ignore them.
Here we want to auto-mount sda1
and when booting.

: Controls the order in which fsck checks the device/partition for errors at boot time. The root device should be 1. Other partitions should be 2, or 0 to disable checking.
