I would like to install Linux Mint 14 Cinnamon on a hard disk with prepared partitions. The partition for Mint has the size 20480,95 MB (40001850 sectors, 2490 cylinders). When I install from the live CD with Ubiquity, I choose "Installation type: Something else", then in the partition editor I select the existing partition for Mint and I click on "Change", because I want to use it as a root mount point "/". But the editor isn't capable to leave the partition size unchanged, and I must choose the new size in MB, so 20480 MB or 20481 MB. I hadn't this problem with the MATE edition or with the older releases. Is this a new bug in Ubiquity? Is it possible to choose the mount point without changing the partition size?
