[inglés] cannot install minino artabros 2.1 from live usb

hello everybody, please excuse me for writing this in english; i do not understand spanish language. i need your help regarding minino artabros 2.1 installation problem. here is my configuration : distro : galpon minino artabros 2.1 installation medium : usb flash disk computer : toshiba NB250 netbook cpu : intel atom ram : 2 gbytes gpu : intel graphics hdd : 160 gbytes dvd-drive : not available i was about to install artabros 2.1 to the netbook that does not have a dvd or cdrom drive, so i boot minino artabros live usb. when choosing where to install grub, minino recognize the usb flash disk as /dev/sda, and netbook's hard drive as /dev/sdb, and then installing grub to MBR makes the netbook unbootable after installation finished. i also tried correcting installation of grub to /dev/sdb1 (root partition on netbook's hard drive), but the result was the same; the netbook becomes unbootable (boot-looping after BIOS screen). any help is appreciated, thank you. -les kompie
