The ultrabok Acer Aspire V5-571G is notorius very hard to fix,everyone is having problem in accesing the BIOS/UEFI menu for changing the bot order,or making the ultrabook booting from USB or DVD. Had this ultrabook for repair,hdd was KO,put another one inside(not nice Acer) very bad design . Had trouble accesing the BIOS,never had the chance to invoke the boot menu. Solution. Burned an Windows 8 OEM ISO at very slow speed.Made an bootable USB from the same ISO with Rufus,select FAT32 and UEFI machine in the menu. Put the DVD in the tray,also the bootable USB connected,then i pressed the ON button for 10 seconds,ultrabook shutted down. Pressed F2,then POWER,heard a beep,kept pressing the F2 until i heard a second beep,and the circle appeared when Windows installs. Hope that helps someone outhere.
