Solved USB Boots not working for installing win 7 on lenovo G400S Tags: Windows 7 Lenovo Last response: October 4, 2013 8:07 PM in Windows 7 Share Tama Handika October 4, 2013 8:00:12 PM Hello all, Im having a problem here, please help me I have an asus laptop with no OS on it, and when its very easy to install windows 7 on it. I just need to set the boot priority to DVD, and its done. HOWEVER, i just bought lenovo G400S with no OS. When i access the BIOS, theres only this option : Booot Mode : Legacy Support Boot Priority : UEFI First USB Boot : Enabled Theres no option to boot from DVD. So, i tried to make a bootable USB using Windows 7 usb download tool. Things should be working now since USB boot option is ENABLED, but its not. My USB still not recognized so it keeps entering the FreeDOS. I have tried to format my USB to FAT32 and NTFS, and its both not working. Do i miss something here? PLEASE KINDLY HELP ME ASAP...i really need this thing done today. Thanks very much for your time More about : usb boots working installing win lenovo g400s Tama Handika October 4, 2013 8:07:14 PM I JUST DID IT So, unlike Asus, i need to press fn + f12 so the boot options will be shown, and i just need to pick the USB.
