My disk partitions are like this : on /dev/sda
/dev/sda1 ntfs RECOVERY 13.1 GiB /dev/sda2 ntfs WIN8 142 GiB /dev/sda3 ntfs data 143 Gib
The recovery partition is for Vista so I'd like to install ubuntu on that. In simple mode, the installer only offer to use /dev/sda2. In advanced mode, it shows the 3 partitions, is it enough to select sda1 and click 'Install Now' ?
