I am running Ubuntu Gnome 15.04, and I want to generate a bootchart to help me diagnose some system problems. However in the guide it says:

enter image description here

So how do I access the grub boot menu in order to append this text? And just to be clear, how should the line look once I have appended the necessary text? Also, is grub already installed for I don't appear to have either or these packages: grub or grub2?

If you want to do this once you can press e to edit the boot line and add the required entry manually.

If you want a permanent entry you need to edit the file 

sudo gedit /etc/default/grub

add the entry at the end of GRUB_CMDLINE_LINUX_DEFAULT and issue

sudo update-grub

the line should look like

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash init=/lib/systemd/systemd-bootchart"

to update the changes.

  • Sorry, I have never gone into grub before, when and where do I press e? –  Aug 20 '15 at 22:55
  • When the system starts and you get the OS selection if you dual boot. – Harris Aug 20 '15 at 22:57
  • I don't dual-boot, can't I just edit the /etc/default/grub file to include that information? Do I need to e pressing bit? –  Aug 20 '15 at 22:59
  • If you don't dual boot you can press and hold first Shift at the start, (I think), to see the grub menu and then e to add the changes. Alternatively, you can edit then grub file. – Harris Aug 20 '15 at 23:02
