Installed Ubuntu 12.04 Feb 2014 - upgraded to 14.04LTS. I believe there is still remnants of older OS's still there somewhere, (they appear on the Grub multi-boot menu at start up).
An earlier version is now the default OS, however, I found by scrolling down the Grub multi-boot screen to the 5th option, I can access to the current working edition of 14.04LTS.
Naturally, I wish to make this the default.
I have edited
/etc/default/grub to “
default="4"”, saved & “
update-grub” to boot in to the option on the 5th line down automatically.
/etc/default/grub now shows:-
- GRUB_DISTRIBUTOR=lsb_release -i -s 2> /dev/null || echo Debian
- GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
Unfortunately this has made no difference to the boot up sequence, I still have to select the 5th line to access a working OS.
I now suspect that editing
/etc/default/grub is not reaching deep enough into
MBR which might explain why my changes have been unsuccessful.
Is there a way of ensuring the
Grub file is the right one in
Can anyone help?
