I am trying to install multiple OS's on my laptop. Getting to three is easy. But then I bump into the ceiling. With only 4 entries in the MBR, I can have 3 primary partitions and then the fourth is an extended partition to point to a chain of logical partitions. I have plenty of disk space, but each OS wants to be installed in a primary partition. I have tried installing in a primary and then moving to a logical but this did not work. The copy would hang on boot. I have a crazy idea that might work. Start over and install XP in a primary partition. Create a bunch of logical partions. Edit the partition table to to make the 3rd entry a primary partition that overlays a logical partition. Install in this pseudo-primary. But there must be some other way to get this to work. If it matters, I would like XP pro, FreeBSD, DesktopBSD, Redhat 8, Fedora Core 5, and Solaris 10. I need two more partitions, one for a fat fs to pass files around from os to os, and a second for an raw Oracle database. My box says "install 99 or more operating systems on a single PC". My modest requirements should be a piece of cake, right?
