I have LLOS 5.8 on a USB external drive. I want to install 6.6 on the same drive and dual boot both. I have 4 additional partitions for this, but am getting hung up on where to put the boot files. The installer is not letting me put the files on the partition I created for it.
Ger are my plans so far: I made a Timeshift of my 5.8 install. My 5.8 install is in 4 partitions. I created 4 partitions for the 6.6 install of which 1 of them was supposed to be the boot partition, but the installer would not let me put it there. I now plan to overwrite the 5.8 boot partition with the 6.6 boot files. I will then install the rest of the files on my other newly created partitions thus leaving the rest of the 5.8 files intact so I can access them to transfer to my 6.6 system. If everything is to my liking, I will delete the older 5.8 partitions. If not, I can always timeshift back to the 5.8 system. Any other suggestions appreciated. thanks
