UEFI Bootable USB Flash Drive - Create in Windows

    This is great and I am very appreciative of the effort you have put into creating this tutorial. But I have a problem.
    I have followed the instructions letter for letter for a clean install of Win 8 on a new system except I formatted the USB as NTFS. Why? Because another guide that I am following in the latest edition of Australian APC mag says to do so. But here's the problem: I insert the USB drive and reboot but the drive does not appear in the BIOS/UEFI boot menu. The USB controller is working because my USB keboard and mouse are working fine. I have tried all available USB ports. Consequently I have no access to the USB. I doubt that this is a FAT32/NTFS issue but please correct me if I'm wrong. Any help is greatly appreciated.

    # Intel Core i7 3770 processor
    # Gigabyte GA-Z77X-UD5H-WB mother board

    Hello visibility,

    Yep, the USB flash drive will need to be formatted as FAT32 to install with UEFI at boot.

    Will confirm that you have to use fat32. I created an uefi boot following this guide and it worked just fine.

    Thanks Brink. So I re-created the bootable USB flash drive with FAT32 and I was able to commence installation with UEFI. But the same problems arose that led me to your tutorial in the first place - black screening before the installation completes. I won't repeat my woes here becuase I have another post where they are covered here.

    Thanks very much for your help and patience.

    Its a great tutorial. Just what I was looking for. I did everything you mentioned. But whenever i start the booting process, I get the following error:
    The application or operating system couldn't be loaded because a required file is missing or contains errors.
    File: \windows\system32\winload.efi
    Error Code: 0xc0000359


    I tried many times and always get the same error. Is it something I am doing wrong?

    Hello everyone. I'm new to this forum and to windows 8 as well. I wanted to create a bootable windows 7 usb drive and I followed every step. I went to boot from the usb drive using the secure boot and then I get into a red screen that says, "Secure boot violation. Invalid signature detected. Check Secure boot policy in setup." I'm not sure what is causing this error. If you can help me out I would appreciate it. Thanks!

    Hello btyanks, and welcome to Eight Forums.

    You will need to disable secure boot to be able to install a 64-bit Windows 7 with UEFI.

    Hello Aneesh, and welcome to Eight Forums.

    Sorry about the late reply.

    Is this for Windows 7 or Windows 8?

    Where did you get your ISO file from?

    oh sorry about that.

    it's for windows 8. the thing is i got this new laptop recently lenovo G580 with windows 8. i wanted to change the partition size. i used easeus partition master to do so. but during the process the computer crashed and i had to format the whole drive and lost everything. also i live here in Nepal and i had this laptop delivered to me from the US by my relative. the other thing is that initially my hard drive was formatted in GPT but i converted it to MBR to install windows 8 from a dvd. so key stored in BIOS was also not detected. and i was thinking maybe if i installed in UEFI mode the key will be detected.

    is UEFI firmware stored in harddisk?

    and about that ISO file, its a 6 in 1 iso. may be something wrong with iso?

    i would really appreciate any of your help.

    Aneesh,

    The product key is imbedded in the UEFI firmware chip on the motherboard.

    Most likely, the 6 in 1 ISO will not work to install using UEFI. That could have something to do with the key not being detected as well.

    If you have Windows 8 installed, activated, and running how you like using "Legacy BIOS", then I wouldn't worry about it.
