Precision M4500 Missing Intel Matrix Storage Manager Post screen (CTRL-I) for raid configuration.

Hi everybody,

On my Precision M4500 BIOS Version A15, after deleting by mistake the volume in the Matrix Storage Manager console, I can't access to this menu anymore. When I start my laptop the Post screen for the Intel Matrix Storage Manager is not showing up and I cannot get into it to configure raid.  I have tried mashing CTRL-I up until it asks for a boot device with no effect.

I also tried to reset the BIOS releasing the battery CMOS without result.

In the BIOS / system information the hard drive is present and in SATA operation RAID On is activated.

With this problem I'm not able to install windows.

Help please.
