I want to install Windows, Mac OS and a Linux distro on my PC. Tri-boot. I also want a big shared data partition.
How can I do this if possible? Any good tutorials, or instructions? I have installation disks.
The only way you can reliably share data between all three OSes is to have a partition in the lowest common denominator, FAT32. Windows, OSX and Linux can all read and write reliably to FAT partitions. Of course, that means you have the limitations and shortfalls of FAT, but them's the breaks.
As for running all three in triple-boot, install Windows first, then OSX, then finally Linux. You should be able to use GRUB when installing Linux to set up a boot menu for your various OSes.
