I am new to Ubuntu and have dual boot Windows 10 & Ubuntu 18.04 LTS. Firstly, everything was running fine, but after one update, Ubuntu started to boot extremely slow. After a couple of hours searching the internet, I figured out that the delay is caused by: 'a start job started by dev-disk-by...' and found that question: a start job is running..., but I am a bit worried that I would screw somethig and I need a bit of help.
My /etc/fstab looks like:
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda7 during installation
UUID=5e550b00-a4ae-4293-a9a0-183c3ca24483 / ext4 errors=remount-ro 0 1
# /boot/efi was on /dev/sda6 during installation
#UUID=B288-94AF /boot/efi vfat umask=0077 0 1
# swap was on /dev/sda5 during installation
UUID=6bd932ca-9689-4507-8536-a1e0a7e5028d none swap sw 0 0
and my gparted looks like: GParted
I am not sure where Ubuntu is located to comment out the proper UUID according to mentioned question?
Also is there a way to merge the highlighted unallocated space with /dev/sda6?
[EDIT]: Can I get rid of /dev/sda5?
