I recently installed ElementaryOS Loki 0.4.1 in my SSD on top of an old Windows 10 dual-boot with Ubuntu 17.04 setup. Ubuntu was in my HDD, so GRUB detected it and included it in the OSes list after booting. But now I wiped it clean and installed Windows 10 in the HDD, so I had to use boot-repair to fix it and followed the standard repair routine. It gave me an error in the end, but the log file wasn't saved to my home for some reason, but the GRUB update worked fine. I can see my elementaryOS and Windows listed correctly on GRUB.

However, my boot time increased a lot (to more than 3 minutes) and I'll include the output of dmesg and systemd-analyze plot.

dmesg is too long to include here, so I chopped some stuff off, but the problems I noticed are related to the Bluetooth apparently, maybe the following lines:

[    9.432748] nvidia-uvm: Loaded the UVM driver in 8 mode, major device number 243

and:

The almost complete output:

And I noticed using systemd-analyse plot that there is a huge gap as showed below: enter image description here

And I also screenshot the detail just before the gap: Plymouth services are the last ones to show up before the gap.

Any idea how to fix this? Thanks!


EDIT: it's related to corrupt partitions apparently, I'm trying to use testdisk to fix it and will post answer if I succeed.

I managed to fix the problem! I followed a similar solution found here.

So the problem was that when installing Elementary OS, Ubuntu still existed and the installation used the swap partition from the HDD that belonged to Ubuntu. And since it has been deleted, the UUIDs were incorrectly set at /etc/fstab, which apparently loads some partitions on boot (correct me if I'm wrong).

By running cat /etc/fstab I could see that it said (not everything included):

/dev/mapper/elementary--vg-swap_1 none            swap    sw              0       0
# swap was on /dev/sdb5 during installation
UUID=9183ee89-60f4-4fe7-bcd4-0c34da15836b none            swap    sw              0       0

But my swap isn't at /dev/sdb5, that looks like something from the old Ubuntu installation. It is actually here:

/dev/mapper/elementary--vg-swap_1

By running sudo blkid I got the UUID for it:

/dev/mapper/elementary--vg-swap_1: UUID="21945fd8-5962-4482-a0d2-abba965c8594" TYPE="swap"

So I simply replaced the old one for it, rebooted my computer and the boot time decreased to:

Startup finished in 3.746s (firmware) + 3.811s (loader) + 7.321s (kernel) + 1.940s (userspace) = 16.821s
  • Good stuff, I have installed additional RAM, and decided I'll just delete the SWAP partition. Shame on me, but your solution seems to have worked for me. – Alex Szabó Jul 18 '17 at 22:42
