Issue: Slow Boot Time on Zorin OS

My Zorin OS is taking more time than desired to boot. In an attempt to diagnose the issue, I ran the following command:

systemd-analyze blame

Here's the output:

927ms snapd.service
896ms dev-nvme0n1p1.device
554ms fwupd.service
541ms udisks2.service
516ms systemd-logind.service

Disable Disk Checking

I attempted to disable the disk checking service using the following command:

sudo systemctl disable systemd-fsck@dev-disk-by\x2duuid-933b47d9\x2d20c0\x2d4d2f\x2d880b\x2d14ca074dbaf4.service

While I successfully disabled the service, so its not showing in the analyze blame command but disk checking is still happening during boot. This has led to a delay despite my efforts.

I aim to reduce the boot time on Zorin OS. The specific issue is the disk checking process, which is taking much time during boot. Ideally, I'd like to bring this down to around 2-3 seconds, similar to the boot time on my trimmed down Debian system.

Aside from Snap items, you can disable the systemd-networkd.service since it is not useful for home users and is more for servers.

sudo systemctl stop systemd-networkd.service

sudo systemctl disable systemd-networkd.service

Everything else on your list must remain.

Using an SSD speeds up boot quite a bit. Wanting a faster boot is fine and all, but it can be risky trying to disable Init items.

Sometimes, you just need to accept that things will take the time they take and use that time to grab a coffee or something.

It should be noted that Windows Fast Startup reduces boot time at the expense of system reliability.

Wow, thanks for this info.
I do encounter some random behavior on my several devices related to booting time on Zorin OS (dual boot mode), some device had longer boot time about 10~20 second (although it's have an identical device hardware).
I'll try to disable Windows Fast Startup now.

From what I've read, Windows Fast Startup is actually a form of hibernation. Which means when you "shut down" Windows, it isn't really turned off, it keeps a grip on the hardware and thus Fast Startup can cause serious problems for other OSes on the same machine. It's recommended to turn off Fast Start before installing another OS.
