OSL 2000

I personally use this nifty little program ,OSL2000 is an advanced multi boot manager. Using OSL2000, you can easily install, boot and manage up to 100 independent OSs in your system. A boot manager is a program that lets you have multiple operating systems in your system. OSL2000 boot manager, in addition to being a normal boot manager, has advanced features that let you seamlessly install, boot and manage 100s of OSs like Windows (all versions), Linux, DOS, etc.

Sweet, but what size of harddrive do you need for 100 operating systems? xD

Are 100 independent OSs really needed though?..
Anyways looks like a nice program, I might start using it.

I personally would never require nor use 100 OS's but i suspect if you would like to give it a shot then you can assume 25gb per OS x 100 OS's = 2,500 GB of space. Figure the space currently used in your default OS so if you had a system with at or above 2,500 gb space i assume it might work. However, with 26 letters in the English alphabet and C: already occupied you may only be able to install 25.
