Want to Dual boot 19 with 18.3 but.... [ Solved ]

Post by AZgl1800 »

I have my partitions set up as follows.

How am I going to be able to specify where to put the LM19 boot/root and make it honor my existing /home /swap /backup partitions?

since you don't have any /boot in the current setup, then you also shouldn't need it in the proposed setup.

in that vacant space, you can create Two New Partitions - - / root & /home - just like there already is . .
- you can call them sda3 & sda4 OR sda7 & sda 8 - - it won't make any difference . .
( primary OR logical partitions )

then use the 'something else' option & select each partition in turn,, marking them as / root & /home,,
and then click on Next to continue with the installation .

Okay, almost got that done, it is allowing me to specify sda3 as the Boot loader partition,
but I cannot find a way to make it take sda4 as the /home partition.... the only option is to format it.

How do you do that when installing a 2nd OS ?

Figured it out, I missed the "mounting points".

and it did not update grub, so did that:

$ sudo update-grub
[sudo] password for john:
Generating grub configuration file ...
Warning: Setting GRUB_TIMEOUT to a non-zero value when GRUB_HIDDEN_TIMEOUT is set is no longer supported.

done


and it now boots up like it should:
