There were some foolish suggestions, the part of going back to 2.0. typo?
Did you mean "delete" or proper method, uninstall?
Apple made it messy, getting better now, but you needed 3.0, and then upgrade to get 3.3.
Apple OS Switcher part of Apple Services msconfig and found in control panel Boot Camp is "handy" but not 100% essential (I ran Mac w/ Windows only and never needed to change default / could be done from Mac side Startup Disk and write the variable to NVRAM).
Going back to 3.0 is all. And when Lion and BC 4.0 came out and were buggy, people needed to uninstall BC 4.0, then go back to SL DVD BC 3.0.
Editorial: (skip if you are so inclinded):
What Apple should have and has transitioned to is to download the newest full package.
That was suppose to be part of Boot Camp Assistant, and intro'd in 10.6.6, but it rarely (10% success?) worked (more field testing, us) and got better with 10.6.8.
Of course with LION this became the only method to get a set of Windows drivers, BCA and wait and download and store locally.
MS Installer Cleanup Utility use to be helpful for such chores.
Turning off services is still possible along wth Startupitems.
Had you asked here, can't recall, but Windows 7 came out after 10.6, Apple though didn't rewrite BC 3.0, they just said, and confused people, with "you need Boot Camp 3.1" and of course in some cases 3.0 was so bad people could not reboot into Windows and HFS read-only was also 'hazardous.'
Sometimes seems like a) $30 for Lion just for drivers, and b) Intel and every motherboard manuf has to provide drivers for their products to add chipset support. And it is not this bad or require old out of date buggy drivers in order to install the correct ones you need.
End Editorial / Back to OP and discussion:
I don't recall in 5 yrs ever once seeing that error code mentioned and posted here. Kind of thing that sticks and I'd remember, and bookmark as well as search on MS and Bing.
