Windows 7 + UEFI Based Install + SD Card/USB Drive = Fail?

    Question

  • I am trying to install Windows 7 Home Premium to my UEFI-based notebook. This notebook does not have a DVD drive though, so the only way for me to install OS's is via SD Card or USB Flash Drives.

     

    I know how to start the UEFI installer because I can do it on my other laptop that has a DVD drive. I also was able to try and start the Windows 7 installer via UEFI on my DVD-less laptop, but it failed to boot after I pressed any key.

     

    Is it at all possible to install Windows 7 in UEFI mode without a DVD?

  • Download and run "Windows 7 USB/DVD Download Tool"
      http://store.microsoft.com/help/iso-tool

    Let the name "Download Tool" not confuse you. This tool is capable of burning ISO images to DVD media, but it is also capable to create bootable USB flash media containing Windows 7 installation media.

    Good luck

  • It didn't seem to fix my problem, if anything, it may of made it worse, before I could just drag the files from my Windows 7 media to my SD card, make the EFI folder structor EFI\boot\ and rename cdboot.eft to bootx64.efi and it would be detected in my UEFI laptop.

     

    Now my laptop doesn't see it at all as a bootable selection for UEFI, even after I do the changes above.

     

    I had to make my Windows 7 DVD an ISO again (via UltraISO) then I ran it though the USB tool (it got to 100%, but then it said it couldn't do something with bootsect, I didn't think this mattered because I wasn't doing MBR boot, but MBR boot works fine)

  • Hi,

     

    For how to install Windows 7 via USB driver, you can refer these articles:

    http://www.intowindows.com/how-to-install-windows-7vista-from-usb-drive-detailed-100-working-guide/

    http://www.intowindows.com/how-to-create-bootable-windows-7-usb-to-install-windows-7-from-usb-flash-drive-using-windows-7-dvdusb-tool/

     

    Please Note: Since the website is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.

     

    That seems you need Windows 7 iso file and your motherboard should support USB boot.

     

    Hope that helps.

  • Nope neither of those helped either. Windows 7 (via EFI install) still says unable to load after I hit a key when it says to.

     

    I'm certain I got Windows 7 to the USB drive properly (I can boot and install from it normally via MBR method), its only with the EFI install.

     

    It would seem silly if the EFI installer only accepted dvd-based installs, but I hope this is not the case.

  • Hi,

     

    I found this article:

    Installing Windows to an EFI-Based Computer

    http://technet.microsoft.com/en-us/library/dd744321(WS.10).aspx

     

    Also please view this link: http://support.microsoft.com/kb/930061/en-us

     

    That seems EFI-Based installer need dvd-based install.

     

    Thank you for your understanding.

  • I figured it out last night. I found a certain post in InsanelyMac forms that helped.

     

    http://www.insanelymac.com/forum/lofiversion/index.php/t184349.html

     

    "Best method would be to use a 4GB FAT32 (not NTFS) formatted USB pen-drive. Extract the ISO or copy the DVD contents to the pendrive, and copy the bootmgfw.efi file to /EFI/Boot/bootx64.efi . Go to http://www.insanelymac.com/forum/lofiversi...dex.php/t186440for info related to Windows UEFI-GPT booting."

     

    I moved the Boot folder from the EFI folder so that it looked like EFI\boot\ instead of EFI\microsoft\boot, then I threw the renamed bootmgfw.efi in the boot folder. Worked fine.

    Did you move it or copy it?  I had tried copying the boot folder and pasting it in /EFI/boot but it seems that did not work.  I also had renamed the bootmgfw.efi to bootx64.efi and placed it in there but can not for the life of me to get it to install as UEFI.  Does it make any difference I am using a SP1 W7 x64 MSDN ISO?
