i am trying to configure a lenovo rd550 with raid, i can configure the raid with no problem, i just can't figure out how to set the raid device as the boot device. i have tried with the on-board 110i controller as well as a 510i add-on controller. same problem with both, i can configure it, but when it comes time to set it as a boot device, it does not show as a boot device. (in the boot order screen)
and of course, when i try to install windows 2008r2, even though i can load the driver, and it shows the raid drive i created in bios, the windows install says it can not be installed on that partition because it was not set as the default boot device in bios.
Sooo, seems like something simple, but i have been working on it for hours and still have no solution.
