Acer laptop, uefi, no bootable devices found
So, got a new laptop, and it started to rain in problems :
1) uefi - what kind of crap is this ?? it cannot detect anything - i have ssd, i have pluged bootable win7 installation usb flash, but it just gives "no bootable device found". Had to turn off uefi and enable legacy mode. Is uefi usable only with windows 8+ ? |

Yeah, with uefi, boot menu is empty, and the only option to boot something is to disable uefi.
