Hi guys!! Thanks for the information helping the OP with his/her/their issue. I'm not trying to take over the thread, but I'm going to run into a similar situation. I'm thinking of getting a laptop (hp/lenovo/dell) that would have windows installed on the SSD. I'm thinking of getting an additional 2G 2.5" SATA and would like to be able to dual boot windows/fed (or rhel). For those of you who've gone down this path. What are issues I need to be aware of that I can resolve prior to getting the box? Questions I should ask the presales tech support? Thanks much!

Even though their Windows installation is not using it as a RAID device. When it is set to RAID in the BIOS, Linux cannot see it. For Linux to run, it must be set to AHCI mode. In my relatively new Dell workstation, this is under System Configuration -> SATA Operations. > > It "should" be safe (all I can say is that it was for me) to go in and verify that your SATA mode is set RAID (in which case this is likely the cause of your problem), set it to AHCI, and then boot your Linux USB stick.

If you were planning to keep the installed Windows system (which I wanted to do), then there is a procedure you can Google for (it might have even been referred to on this list) that will allow the Dell-installed Windows to boot in non-RAID mode. I followed the directions and can now dual boot Windows and Linux out of the GRUB menu. > > > I believe I have shared this link before on the list.
