I just wanted to post this information in case it helps someone.
Most guides for dualbooting always assume the user is making a 2nd partition, but I think its safer to use a 2nd HD. It can be safer to add a spare or external HD to your computer and not risk your main system, especially since Haiku is still an alpha : )
VirtualBox / VMware / QEMU work fine but don’t let you know if Haiku actually works on your system nor can you help out as well in bug reports.
Here is the link to my post in the Ubuntu forums, since I am dual booting with Ubuntu Studio 9.04:
I will be adding my hardware to the Haikuware database.
