Am trying to install Ubuntu alongside Windows Vista. So far I have three primary partitions (windows) (Eisa) (Recovery). How many Linux partitions (root, home, swap) can I create on free space without running into a conflict with Windows? I haven't been able to find specific answers for that when I search.
If you're using GPT and UEFI, you're not going to have a problem. It just works.
MBR is tricky, though, as it has a cap of 4 Primary partitions. Fortunately, you can get around this by creating what's called an "Extended Partition." These things can contain almost infinite other partitions.
When you use the Ubuntu install disk, load up GParted and make all the free space you want. In that free space, make an Extended partition with maximum possible size. Then, place your EXT and Swap (about equal to your memory) in the extended partition. Run the Installer and select "something else" when asked about partitions. Choose the EXT partition and make that your
/ mount point.
