I have Lubuntu 20.04 on an old laptop. I like it. I’d like to put Pop OS 20.04 beside it and evaluate them side by side. Pop isn’t making this easy. First thing to note is that this is a BIOS situation, not UEFI. I’d try rEFInd if I was booting UEFI.
I’ve got Pop 20.04 live on a USB stick. I use mkusb for this. The first thing I found was that mkusb won’t make a persistent live installation of Pop OS. Ok, well, I didn’t really need that but it would make trying it out easier. So I thought I’d dual boot it beside Lubuntu.
This seems not to be straightforward. The installer doesn’t offer the option I’m used to seeing with Ubuntu flavors to install along side the existing system. I resized Lubuntu and left half the hard drive empty and tried it anyway. The result was that my laptop would only boot to Pop OS.
I monkeyed around with grub in a Lubuntu live envrionment and broke it completely. I figured I was missing something (duh) so I deleted the partition where the new Pop OS lived and fixed grub to boot Lubuntu. Now I’m back to where I was before I attempted to install Pop beside Lubuntu.
The way to do this for now seems to be a bit of a mystery. I read that System76 intends to put the “install alongside” thingy back into their installer in a future release. I’d rather not wait for that.
What would you do?
