After a series of hickups, I have recently ended up with a need to reinstall Win 7 on a Dell Inpiron 7250 that came with an SSD and a 1Tb hdd. Hardware diagnostics show no error. The problem is that when i attempt to reinstall the OS from OEM DVD the Bios menu is set to Intel Rapid Storage, but the install is not possible. There appears to be no drives to install to. With the BIOS set to AHC setup does run , but I end up losing the SSD and Intel RST funcionality. Having quickly skimmed Intel's manual it appears that what I am missing is: Rapid Storage Technology option ROM. How do I reinstall that?
I would need a step-by-step foolproof set of instructions that starts from a totally clean system. One cannot help but wonder why the OEM setup DVD is not able to set the system up from scratch.
