I am running a dual boot with ubuntu on a seperate SSD and Windows on another SSD. It's taking far longer to boot up ubuntu that it should be. I tried changing my grub settings to skip the menu and boot right into Ubuntu which didn't make much of a difference.

My ubuntu boot loader is installed on the EFI partition on the Windows disk instead of a partition on the Ubuntu disk which I've read is fine but I'm wondering if that might be the issue.

The results from systemd-analyze are:

startup finished in 11.993s (firmware) + 4.860s (loader) + 8.598s (kernel) + 9.461s (userspace) = 34.913s 
graphical.target reached after 9.451s in userspace

system-analyze blame gets me:

Windows will boot in 8 seconds so I'm not sure why the firmware + loader + kernel are so long for ubuntu.

  • Some things to review. https://askubuntu.com/questions/1284302/is-it-possible-to-make-ubuntu-20-04-boot-faster/1284332#1284332 But firmware being so long is unusual. What brand/model system? You may need UEFI settings. I turn off some so it does not try to look for network boot, I do keep fast boot off. My Skylake system is 9.5 sec for firmware. And you realize Windows is not that fast as it uses fast start up or cache for booting. – oldfred Nov 07 '20 at 21:56
  • If you check, Windows in not fully shutting down, You can use suspend in Ubuntu to get a similar effect. – C.S.Cameron Nov 08 '20 at 05:00

Try upgrading your motherboard's firmware to the latest version. This should be routine maintenance but most people neglect it.

On my work desktop, doing this took nearly 3 minutes off my start up time.

  • I have tried that and there were no updates available. – Mukhil M Nov 07 '20 at 21:39
  • That's a pity. Well, it sounds like a lot more troubleshooting is in order. Have you disabled Win10 Fast Boot? Ideally, disable hibernation completely: open an admin command prompt and type powercfg /h off. You also look to have a lot of Snap apps -- each one creates a loop device. If you don't need them, or there are native packages, remove them all & then disable Snap support. I have done this on my headless Ubuntu Server RasPi4 & it gave a small improvement in startup time. – Liam Proven Nov 10 '20 at 12:37

    So I have fast boot turned off in windows so I can access the drive in ubuntu if needed. I can remove the snaps like opera and discord but I'm not sure if/how I can remove the snap-gnome packages, are those not part of the desktop interface? I don't have any other snap packages so not sure why there are so many loopback devices. – Mukhil M Nov 10 '20 at 20:13
  • Do either of these help? Sorry, I do not run the GNOME version of Ubuntu myself.

  • So it looks like I'll need to keep the gnome snaps if I want the default gnome apps to run but removing a few did free up some space and shave a bit off the boot time. Thanks for the help. – Mukhil M Nov 12 '20 at 22:08
