I have an old HP laptop that I wanted to put Lubuntu on (It had Win 7 on previously). I booted from my USB, installed Lubuntu but when I tried booting from laptops hard drive I got:

non system disk or disk error

error. Has anyone encountered anything similar and if yes do you know how to fix it?

  • Can you run boot-repair and if that doesn't fix the problem, edit your question and provide the log. If it does work, please leave a comment.

    FYI: Lubuntu and flavors of Ubuntu have shorter lives that the main Ubuntu. Yes Ubuntu 14.04 LTS (from 2014.April [yy.mm]) is supported for 5 years, Lubuntu 14.04 LTS & other flavors only had 3 years of support (for desktop & all packages not found in 'main' (or from Ubuntu itself) - thus I'd suggest re-installation of a later release of Lubuntu that is fully-supported instead of using a release that only has some packages supported, others being EOL.

Using fdsik I figured out that there was no bootable partition so I did this:

fdisk  /dev/sda

Command (m for help): m

Command action
a   toggle a bootable flag
b   edit bsd disklabel
c   toggle the dos compatibility flag
d   delete a partition
l   list known partition types
m   print this menu
n   add a new partition
o   create a new empty DOS partition table
p   print the partition table
q   quit without saving changes
s   create a new empty Sun disklabel
t   change a partition's system id
u   change display/entry units
v   verify the partition table
w   write table to disk and exit
x   extra functionality (experts only)

Command (m for help): a

I only had one partition so it was automatically set to that one. After that everything worked fine.
