First, make sure this is the driver you are using: When you created your Logical Drives, did you also Initialize them?  You could also try installing via USB key - this is how I do all of my installs any more: [URL] There was a similar issue for me that ended up being a weird DVD drive issue - it would install every OS except for 2008 R2 - but it was isolated to only one drive though - other drives that were exactly the same make/model/firmware worked fine.
Hi, I attempt to install windows 2008 R2 on a PE 2850, but it's not working. The problem is that windows doesn't recognize the hardrive (when I should choose on which partition I want to install the OS). I tried to load the driver PERC 4e/DI RAID v6.46 (from the dell support website) but it says that the driver is not digitally signed. The installation is working with Windows 2008, the driver version is 6.50, so I took it and loaded it during the installation of 2008 R2 but it is not working eather (same message). I also tried with the driver from lsi.com, the driver version is 6.51, it is digitally signed but it's not working for 4e/DI (4/Di, 4e/DC, ... but not 4e/DI). Do you have any idea how to resolve this ? can dell do something about it ? Thanks
