I've been trying to solve the following problem 5 good hours now. I've recently installed Linux Mint 17 with LVM, erasing my hard disk. For some reason I want to dual boot Ubuntu 12.04 alongside my previous installation, without losing any data, but LVM is not supported by 12.04 and now I'm stuck. I've managed to resize the logical volume to free up some space, but this is hopeless anyway, because I cannot resize the physical partition to free some space for a new installation.
Is it possible to resize the physical partition? Some people say yes, some people say no and I'm quite lost in it because I'm an inexperienced linux user.
Any thoughts?
