Hello   I thought i had to create a RAID by enabling it in the BIOS and by deleting all the virtual disks in PERCs300 GUI. Bios Not Installed  No Virtual Disk found. is now what i get and when i try to boot to a DVD i get nothing.    Turn the SATA mode back to ATA in the system BIOS. That controls the S100 RAID controller that is part of the system board chipset. It should not be set to RAID mode if you are using an S300 controller; Which is a PCIe card version of the controller. After you get that set correctly you should have an option during boot to enter the S300 controller BIOS. Press the key combination and enter the BIOS. Configure your RAID array and exit. After that you should be able to boot straight off of the 2008R2 DVD and complete the install. If it still does not detect the storage then boot from the SBUU to complete the installation. If you need more help then provide more information. For instance, if you just installed this S300 then you may not have it cabled correctly. Knowing more about your situation means that I have to make less assumptions when providing an answer. Thanks
Im a novice admin with poor patience and i think i screwed up majorly on reinstalling OS 2008r2 I thought i had to create a RAID by enabling it in the BIOS and by deleting all the virtual disks in PERCs300 GUI. Bios Not Installed  No Virtual Disk found. is now what i get and when i try to boot to a DVD i get nothing.  So please help out a NOOB who is now fearing a long and painful sunday night at work... PowerEdge R510, most likely seeking BIOS firmware that can be flashed so i can go ahead and use SBUU to install windows 2008 r2 ANY AND ALL HELP WILL BE AMAZING AND GREAT KARMA WILL BEFALL YOU!
