Acer AspireOne D250-1151 Reformat Problem

Hello, I have read other posts where the people are telling to reformat windows automaticly on AspireOne D250, you should press Alt Gr + F10 before windows start loading. I tried by pressing it in many different ways, but the only effect I've got was some noice right before the windows start loading. After the noice, it started loading, like I did nothing. Also I check'd my bios D2D Recovery option was enabled. If you have any ideas how to activate the reformating option please tell me.
