I recently bought a Dell PE 2850 that was used by a small company. It was running CentOS but I deleted the raid and formatted the HDDs. I have a raid but I can't install the OS. I've tried using bootable Usbs. But nothing worked. I've tried windows server 2012, 2012 r2, 7, 8 and server 2008 r2.
I tried installing 7 from a disc.
Its bios version A02,
Thanks
