Hi ! i have a Toshiba portege Z930 ultrabook with no optical drive. it came with win7 64bit preinstalled and with a windows 8 installation DVD. The SSD (an msata drive) crashed so i had to change it with a new one, so i don't have the OS RECOVERY option from the bios... Ok so now i have a blank SSD and no optical drive, and no way to go back to the factory default installation. I'm actualy trying to install windows seven 64 SP1 with an usb key (i used RUFUS to create it) but unfortunately it doesn't see my SSD...so i guess it needs a sata driver, i went to Toshiba support site and didn't find anything ike that. i just found the intel storage driver so i downloaded it, uncompressed it in another usb key and tried with that. it finds and install the driver but still no HDD found...i'm stuck at this point. Thank you very much for your help.
