My daughter got her one back from repair (ssd broke) so i have to put Mandriva back on it but it took nearly 3 hours to install it from a usb-stick. The first time it took also very long to get Mandriva installed on that acer one, on my eeepc 701 it took nearley half a hour to install it from the usb-stick. D2D is disabled in the bios, is there a reason why the installation takes so long
