Windows 7 Enterprise T61p

[reapur]

Hi,
I have a weird problem maybe someone can recognize and help me out.

I have a T61P that came with vista home premium. I do not want to upgrade to windows 7, I want to do a clean install.

When I try to install with the Windows 7 enterprise DVD, I get an error, upon the start up of the installer in GUI, that a CD/DVD driver is needed or something, it's not a clear message. And the installer will not go any further.
Here's the exact verbage:
" A required CD/DVD drive device driver is missing. If you have a driver floppy disk CD, DVD or USB flash drive, please insert it now.
Note: if the windows installation media is in the CD/DVD, you can safely remove it for this step."

When I try the same with Windows 7 Ultimate, everything works without any problems

!!

I have put AHCI in compatibility in the BIOS.
I have also loaded the Matrix driver on a USB stick and tried to have the installer load it, but it said it wasn't needed

The reason I want to use enterprise is because I can get a real license thru my company's MVLS for like $20 whereas the Ultimate is an MSDN license and I'm not sure when that expires.

Any ideas what this is all about?

Odd, maybe it didn't burn correctly? Tried a different DVD+R?

very odd. I just got done testing another DVD I burned on my other machine.
Same result

If the licenses obtained through MSDN are anything like those obtained through Technet, they never "expire." I'm certain that licenses obtained through Technet never expire. But software obtained through Technet is supposed to be used for "evaluation" and testing and not in a "production" environment. But my understanding is that MS is very liberal in interpreting evaluation and testing and basically doesn't care as long as you are not giving away or selling those keys and are not using them in a "production" or business environment. So extended home or personal use is generally OK, at least for Technet keys. But again, they never actually "expire" as they are the same as full retail keys.
