i would have been the one who setup those dual boot macs for you, and i would have been cussing the entire time. i would rather dual boot windows/linux, it can be troublesome but easier. try a pc that dual boots with apple osx.
fyi, companies like asus don't make the systems, they make components for the systems. you may find an asus, acer, samsung, hitachi etc...branded parts made to the oem specifications but they don't make the systems.
I setup the dual boot systems myself. It was actually incredibly easy. I had them running Win 7, with VMWare player running a Win Server 2k3 host and Win XP host for our lab. I never cussed the mac's once. Before the imac's we used dualboot macbook pro's, same thing, easy as pie to dual boot. So it would appear to me the consistent issue in your problems is the operator. I used the mac to run a 3 day firewall training course. On average I'd run 12 courses per year. So their bootcamp functionality is something I'm quite familiar with.
Asus DO make the systems. They have done for many many years. I used to work quite closely with them (I worked at the NZ Distributor for Asus for 5 years). We had tours of their plant. I can assure you they were happily spitting out HP, Sony, and Apple laptops at the time (in quantities that were mind boggling 9 years ago).
You ever think now might be the time to zip it? That hole you're digging is getting mighty deep.
Oh look there's even a wiki article, a little out of date but you get the idea:
