I press the intall now button. A message is displayed: A required CD/DVD drive is missing....

The installation stops there. I've inserted a floppy but the install will not take a SATA driver (ICH10R).

The computer is an X58 chipset running Intel 920 with 12gb memory.

Any suggestions for fixing this? thanks

I am having the same problem. The Windows 2008 Server setup accepts the "82801HEM/MBM SATA ACHI" or "ICH8M-E/M SATA AHCI" driver but still indicates that there are no drives and it needs more drivers. It may actually be a different issue, as when I tried mounting a drive that actually had files on it, the files showed up just fine.

This link indicates that it may be an issue with the DVD image: http://forums.virtualbox.org/viewtopic.php?f=2&t=19581

The eng_windows_server_2008_r2_st_ent_dc_web_retail_x64_X15-50365.img file that I was trying to use was listed at about 2.03GB, but I found an ISO on MSDN that is about 2.8 GB, so it may indeed be an issue with the image file being corrupt. I'm going to try downloading the ISO from MSDN tonight and will see if that fixes the problem.

EDIT: Yep... That did it. I guess the IMG file was missing some drivers. If anyone else gets a "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." error message make sure that you installation media is not corrupt.
