Use this link to download the driver, extract it to the USB key: [URL] There are 2 drivers, one is for installation from inside Windows, this one is used during installation from a USB key.  Let me know. Regards,  
Hi all,  We have a Dell PowerEdge R420 here at work. It has a PERC 710 mini in it. There are 3x 600GB SAS drives currently in a RAID 5 array. I am trying to get Windows Server 2008 R2 installed, I have a legit disc with Serer 2008 R2 x64 SP1 included and obviously when I try install it it asks for drivers. I have downloaded the drivers for the 710 put it on a flash drive, Windows finds it and makes use of it but then states that no new devices could be found.   I used the service tag to get the drivers for the 710 mini, so do not see how the driver could not be the correct one. So here I am asking for some assistance. I am willing to break the array and recreate it  (give me the steps if you'd like, incase I am doing something wrong). I will try it all.  The server use to be live and working fine, there were some issues and the technician who was at the site before me stated it was the RAID controller. Dell came out and replaced the RAID controller as well as cable. I then took over the site and am now left with this. The data on the drives is not yet important so does not matter if it is scrapped.
