I just received a shipment of dell Optiplex 9010 Minitower Windows 7 computers (16 GB memory). General practice where I work is to wipe the hard drives and install our Enterprise version of Windows 7. The computers came installed with the new UEFI bios (which I had never seen before now). Standard practice would be to kill the pimary Wndows partition and re-install Windows on the clean partition, keeping the Dell System partition intact in the remote event we would want to restore it to factory default. However, UEFI would not let me delete a single partition. It made me delete all the partitions before I could manipulate them. All good I figured since I really didn't care about those 2 dell/system partitions anyhow. So... the re-install went flawless and everything works fine... except the ATI drivers won't install. The Dell-supplied card is an ATI Radeon 7570. The windows drivers work fine, but I need to install the Catalyst software for the users and dual-display funcionality. As it sits with the MS Widows drivers, it won't recognize dual displays. This is on ALL of the computers I did a clean install on (10 of them). The ATI software acts like it's installing and even says it comletes the install, but the drivers arn't present and the Catalyst software never gets installed. The install only takes about 10-15 seconds, so I know it'snot installing eveything. I would expect a full install to take at least a minute. I tried older Catalysyt drivers, beta drivers, everything. Nothing will install but I get no errrors anywhere. Not in the ATI log and not in the Windows logs. Could this have something to do with UEFI? In the bios the only video option is Dual Displays on or off. Either setting gives the same result. I checked the computers out before I wiped them (to make sure they booted) and they had the catalyst drivers installed before I wiped them. Anyone have any ideas? Any help would be greatly appreciated. Thanks in advance!
