Can't boot up into Mepis 11

#1 Postby Toastrack » Fri Feb 24, 2012 3:37 pm

I have just installed Mepis 11 from a live cd, folowing (I hope!) all instructions to the letter. I chose a separate partition from my Mepis 8.5 partition, with the aim of a dual-boot option until I am happy with the new setup. The partition size is ample - lots of Gb. I chose to use the same swap partition.
I installed grub on the same disc.
The install seemed to be straightforward, and then I did the reboot as instructed, without the cd inserted.
Lo and behold, there was no Mepis 11 option offered, and it booted up into Mepis 8.5, same as before the new install of Mepis 11!
All this, by the way, on a 32bit x86 type machine.
Examining partitions in Dolphin, it looks as though all the Mepis 11 stuff has installed to where it should be, complete with a new Home directory. And of course all the old 8.5 files are safe and sound in their original place.
Question - how do I get to boot up Mepis 11? Has the grub install gone wrong, or do I need to do something else?
I did understand that I might hve needed to add the Mepis 8.5 to the grub, but not the other way around. I have not yet tried another install, waiting rather for some informed guidance. :confused:

Had you installed grub to the MBR I believe it would have picked up all systems. But installed on the M11 partition, your grub from M 8.5 is detected. You need to chainload to the M11 partition, by editing the 8.5 grub.
I can be corrected by those who install to a root partition. I always install to the MBR so I am only giving my inexperienced opinion.

How did you install while running from the LiveDVD?

There used to be problems with the grub install if you had logged in (at the KDM login) as root and did the install while in that root owned KDE session. If you had logged in as "demo" user and then ran the installer, grub installed correctly. I don't know if that ever got fixed or not.

Maybe post your Mepis 11 /boot/grub/menu.lst.

Since you installed grub to the M11 partition, your M8.5 install still controls the boot, and M8.5 doesn't know anything about your M11 install.

You need to add a stanza to your M8.5 /boot/grub/menu.lst file that points to your M11 install.

You are exactly right. His M8.5 install still controls the booting, and he needs to edit his M8.5 menu.lst to include M11 as an option.

Far easier to use the System Assistant from a booted LiveDVD session to reinstall GRUB.

You can use either the Mepis 11 LiveDisk or the Mepis 8.5 one. Whichever you do use, install to the MBR and make sure that it is pointing to the correct partition. IE: if using the Mepis 11 LiveDisk, point it at the Mepis 11 partition; if using the Mepis 8.5 LiveDisk, point it at the Mepis 8.5 partition

Either method will enable booting to both operating systems (and any others that are on your system).

Naw. It would take about 30 seconds to edit /boot/grub/menu.lst.

Of course, if you don't know how, the live disk with it's pointy-clickity interface will get the job done.

Considering the trouble the poster got into (and how), I thought it might ease the job a bit.

Thanks to all for the suggestions. I understand what's happened OK, and did what I thought was the easiest, which was to copy the relevant Mepis 11 menu.lst lines over to the Mepis 8.5 menu.lst so I have the choice of which installation I want to run. Sounded simple.

OK, the options all appear correctly at the start of boot-up, but then there's a problem. Mepis 8.5 and Mepis 11 label the discs and their partitions differently, although all the partitions are seen OK. But whether in menu.lst I use the 8.5 or the 11 type identities, if I choose Mepis 11 I get the message "No such partition ....", and have to choose the 8.5 installation to run Mepis 8.5.

The 8.5 labels my three discs (all partitioned) as hda1, hda2 and sda1; the Mepis 11 labels them sda1, sda2, and sda3 respectively. But which ever labelling system I specify it still says there's no such partition.

Would a fresh install of Mepis 11 be more straightforward, assuming I know the correct place to tell it to put grub ?? :confused:
