    • Make sure you are not using firewall/antivirus program or browser extension blocking the referrer part in the http request.

  1. WinSetupFromUSB says that the file is to large to add to file-system < 4GB. but exfat can handle files bigger then 4gb …

    • You should’t be using exfat as it’s not supported for booting in EFI mode, thus no advantage over NTFS. If it was ok, do you think it would have been included in the format options and get away from the common problem you are having ? 😉
      Besides, xp and 7/vista bootmgr also do not support booting from exfat.

  2. Windows 10 TP BOOTMGR does, and that can be used for booting windows 7/8 install too 🙂
    quick google later… win 10 apperently does support exfat for efi mode too.

    • And what do we do with people willing to put Windows 7 on exfat? I cannot redistribute bootmgr as per Microsoft limitations.
      Besides, exfat and efi boot is limited in EFI firmware, not only in bootmgr or Windows in earlier versions.
      As far as I am aware, there are some manufacturers which implemented NTFS support for EFI boot, there is also a NTFS driver for EFI, details in the FAQs, but haven’t heard anything for EFI in this regards, please correct me if I am missing something.

  3. Apparently an exfat EFI driver can be found here: http://efi.akeo.ie/
    Why not put an Information box saying that you will need too manually copy and replace the bootmgr from win7 with the one from win 10 (for advanced users)…

    And in other case not support formating the drive as exfat, just support the creation process… The error message of “file is to large to add to file-system” is so wrong it can be as exfat does support files larger then 4GB.
    Please just remove the error message about that and update grub (and/or grub4dos) as later versions of it does support exfat as well…

  4. (Apparently didn’t work posting in the download-section, so I’ll try here… sorry if this becomes a double post)…

    Is there somewhere i couyld download a beta version?
    There apparently was over a year since the last stable version and no telling when the next one is going to come out…

  5. A couple of questions….

    How do you sucessfully mount an iso in the windows 8 setup? do you modify the boot.wim in any way?
    I have tried to accomplish the same thing myself many times, but he will never read the iso mounted from grub in windows 8 setup…
    Where do you install the imdisk driver into the setup program?

    • Boot.wim is modified, executing a small program which waits for the USB disks to be initialized, installs drivers if that advanced option was used, installs imdisk, then searches for the given ISO, mounts it and starts the Setup.

      Grub4dos mounted ISO is gone when system switches to protected mode, this applies to any OS, except the ones which are real mode such as DOS.
      Windows has no clue what grub4dos or any other program in real mode did, unless a special driver for this purpose such as firadisk or winvblock is used.

  6. Thanks.
    I found what I’d missed (did not run the “diskpart rescan” command after mounting the iso via imdisk).

    An idea for the setup.
    Why not use an Autounattend.xml and a cmd file in the root of the usb to do those things…?
    That would remove the need too modify anything within (or from) the iso and thereby making sure of compatibility with later windows versions (and those discs with multiple windows editions in one iso, and so on)…

    (Works on Vista and later)

    • That doesn’t work for USB hard drives and when it does, it can’t help to install drivers before USB disk is accessible, i.e. install chipset/usb3 drivers to help showing USB disks on USB3 ports in Win7 for example where there is no USB3 support. Besides, on some systems usb disks might take long time to show up, and setup does not wait for them everything custom fails. Currently the custom program waits this to happen and rescans disks until the iso is available.

  7. If you check the WinSetupFromUSB-1-4.exe file with virustotal.com, you’ll get some warning (5/55) about a possible trojan. This is annoying. Please add a short statement on your page, that the file is actually virus-free.

    regards,

    • I’ve done that many times, also writing to all AV vendors detecting something. The few left cannot be contacted or simply don’t respond. You might also pay attention who is detecting and decide for yourself how well trusted they are and whether one should be bothered at all with their results.

  8. I’ve tried to burn windos XP or Hirn on my flash memory but the program always tells me that there is a something went wrong so iam asking rof help
