Hi, I have Windows Xp Pro in my first har drive (master) and I have a second drive (slave), wich is empty. What I want to know is, what do I have to do so I can install Windows 98 SE without re-installing Windows XP. But I want this in a way I was operating in Win 98 and I could install things (programs, games and so on) in the hard drive wich haves Win XP and vice-versa. If this is possible of course. I was thinking in changing the first hard drive from master to slave (wich contains win xp), then change the empty drive from slave to master, then I would install win 98 in that drive and finally I would install bootmagic to choose wich Os I want to work with. Basically what I want to do is have Win XP and 98 on the same machine without having to re-install Win XP and I want in a way that I don't get problems. One more thing if I make this work with both OS do I have problems for installing nvidia drivers for 2k/XP on win xp and then the nvidia drivers for 98 on win98? And do I have to install directx in both (in win xp is already installed the lattest)? Will I get any problems with this sort of things? Thanks in advance.
