How can two LL versions be mutually compatible on one physical hard drive? - m654321 - 06-08-2016

One of my laptops has LL2.8 installed on its HDD, along with more than 20 other distros.
I have just installed LL3.0 next to 2.8, the newer version now being in charge of the grubscreen.
However, though I can boot into LL3.0, when I choose to boot from LL2.8 (selecting it from the grublist) it refuses to boot.

Therefore, it seems that when I install two different versions of LL (on the same HDD), only the last installed version is bootable. Is there something I can do so that either version is bootable (i.e. they are mutually compatible) or am I just stuck with being able to boot only the last installed LL version?

Many thanks for any comments or advice on this...

You can run 2 versions of LL on same HDD (I am with Win7).. You'll want to update grub..

The command from terminal is...

Code:
sudo update-grub

The BUT is... you have 20 other distros and 2 LL.. Smile

When I updated grub, the LL3.0 grub took over - not a big deal for me but for you, maybe the 2.8 is preferred if it was customized??

Searching grub from the main page will yield lots of info on the subject...

I assume no problems booting the others distros?

No glitches at all with the 27 other distros, including LL3.0, all installed on a single 1TB HDD on a Dell D630 laptop - they all boot perfectly (following selection from the grubscreen) and work normally, except LL2.8. All the operating systems I've used are 64-bit.

As mentioned in the first post of this thread, LL3.0 was the last-installed OS (and boots fine), LL2.8 was the second-to-last-installed OS (which did boot perfectly, until I installed LL3.0 alongside it). Grub was updated previously with 'sudo update-grub' but didn't help with LL2.8 booting. When I select LL2.8 from the grubscreen I get the following message:

Code:
error: filename expected

Press any key to continue...

Pressing any key to continue doesn't appear to fix the problem: it just returns me to the grubscreen list of operating sytems.

In general, I've noticed that LL only works, i.e. boots normally, if it is the last OS that's been installed in any dual-boot or multiple-boot set-up.

same thing here .
Had LL 2.8 try LL 3.0 Now 2.8 is dead i get
error: filename expected
Press any key to continue...

Both LL are 32 bit.

Play and learn.

arxontas - thanks for adding that you have had the same experience - I still haven't been able to fix it.

It would be good to hear from someone who has experienced this problem & fixed it.
Maybe Jerry has different versions of LL installed & all bootable on the same PC..?

What I used to do was change the GRUB_DISTRIBUTOR= line in /etc/default/grub file to something like this and then update the grub on that partition, you might have to update the grub on your primary grub distro too.
Good luck friend Smile
