I recently installed Kali Linux in triple-boot with Windows 10 and Ubuntu 15.10. Before installing Kali, both Win and Ubuntu boot quickly. Now Win boots normally and so does Kali, Ubuntu instead takes up to two or three minutes to boot.

This link shows the output of dmesg

Is there anyone that could help me to bring back my Ubuntu boot time normal?

    You can run systemd-analyze blame to get a list of the times for each service startup. – mchid Feb 01 '16 at 19:07
  • Updated the question with systemd-analyze graphic. I think bluetooth is the cause of long time boot. Isn't it? – MKay Feb 02 '16 at 18:39
  • Thanks. For future reference, it would be better just to copy and paste the terminal output of the command (non graphic version) although I must admit the export as an svg image option is pretty neat. – mchid Feb 03 '16 at 21:48
  • To post a large body of terminal output, first, copy and paste the text from the terminal into your question. Then, highlight or select the body of text. Finally, press CTRL + K to automatically format it as code. – mchid Feb 03 '16 at 21:50
  • Actually, can you please post the terminal output instead as the text is so tiny on the svg version that I cannot read it using my browser where it is posted. Thanks. – mchid Feb 03 '16 at 22:16
  • I'll add the output within 10 hours. Thanx for your suggests about code! Anyway you should be able to download the svg and zoom in and out the image. – MKay Feb 04 '16 at 08:22
  • Added the output of systemd-analyze. In this you don't find bluetooth, I rfkilled it on startup but this didn't improve boot time! – MKay Feb 04 '16 at 18:01

Found out the issue! After installing Kali, SWAP partition automatically changed its UUID. It was enough changing UUID of SWAP in /etc/fstab to get Ubuntu booting fast back. I found the problem analyzing the output of journalctl command.
