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:
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
add the entry at the end of
GRUB_CMDLINE_LINUX_DEFAULT
and issuethe line should look like
to update the changes.
