|I seem to be lost on the 10 OS contigency reasoning. |
For what it's worth, there are only so many OSes that are prevalent on home PCs & the majority of them are all under the Windows umbrella. While multi-booting is not nearly as cumbersome as it used to be years back, it still requires some due diligence & even when you've managed to load all the plethora of OSes you desire on the machine, you do realize you aren't going to be spending much time on the majority of them at the end of the day & they are going to end up pretty much taking up space that probably could be better allocated to data backup or file storage. So, you might want to think this 10 OS thing through before embarking on it.
I've had Kubuntu; XP Pro & Vista on this machine for a while, then I added Server 2008 Enterprise & Windows 7 later came onto the mix as well. I pulled the Linux & Server 2008 install recently as I haven't really been booting into neither that much as of late. IMHO, if you are pretty much set on installing several OSes on the machine, you may want look into virtualization, since it could save the unending reboots when you have to switch from one OS environment to another.
