I recently purchased another laptop for work. Of course, I immediately wiped Windows 8 from it. Then I installed Ubuntu 12.10. I wanted to allocate 20% of my 500GB hard drive to Ubuntu and leave the rest alone to install a few other Linux distros.
To my knowledge, this is exactly what the Ubuntu installer did. However, now that I'm looking to give ElementaryOS Luna a go, I realize that the partitions are a bit different than what I was expecting.
/dev/sda1 FAT32 Mounted at /boot/efi Size: 190MB /dev/sda2 EXT2 Mounted at /boot Size: 244MB /dev/sda3 LVM2 PV Ubuntu Size: 465.34GB Unallocated Size: 1.02MB
20% of /dev/sda3 is listed as being used (which is exactly what I selected at install to reserve for Ubuntu) even though I don't have anywhere near 100 gigs of data on this computer. Is this a typical method for Ubuntu partitioning as opposed to simply leaving about 400 gigs unpartitioned? And if so, how can I safely go about reserving some space for other distros without risking my data?
