If I got another hard drive how would you dual boot with windows 98 on one and linux on the other?
I'm not 100% sure on this, but I suspect recent linux distros might even autoconfigure a windows option into the bootloader for you.
RedHat and Mandrake certainly do, and have done for a long time. If you're installing RedHat simply plug your new, unformatted drive in as slave or secondary-master, make sure Windows is still happy to boot (but don't let windows format the new drive, if it asks!) then go ahead and do a Linux install. RedHat will confidently install to a blank or previously-linux-formatted drive, but it's very cautious about overwriting other operating systems unless you specifically tell it to. And it'll automatically set up GRUB to dual-boot with whatever OS was already installed. (If you're still not sure, just bring the machine along to a meeting; most of us have done this before :) --- This email has been sent on 100% RECYCLED electrons!
