Can't install Windows 10 from bootable USB with UEFI - Dell Latitude E7470

Hi there,

I've really been struggling with this: I'm trying to install Windows 10 from Dell USB drive that I've made bootable, but it's only seen in the legacy options in the one-time boot menu. Secure boot is off and UEFI is enabled. I need the USB to be recognized as UEFI in order to install Windows to boot to UEFI. I'm using Rufus to make the bootable drive and I've tried both MBR and GPT partition scheme for UEFI with no luck. Is there any BIOS settings I need to check?

One thing folks may not realize is the Flash Drive has to be formatted as FAT 32 in order to boot as UEFI..

It also has to be an x64 version of the OS.

The tool recommended will create such a flash drive but downloading directly to a Flash Drive can be slow.

The media must be at least 16 gigs and not larger than 32 gigs and USB 2.0.

This is why I recommend using USB 2.0 optical drive and OEM system builder DVD for reinstall.

It also means that ISO must be burned to DUAL Layer DVD media because the base installer is no longer smaller than 4.7 gigs.

Why the limit?
The 4 GB barrier is a hard limit of FAT32: the file system uses a 32-bit field to store the file size in bytes, and 2^32 bytes = 4 GB (actually, the real limit is 4 GB minus one byte, or 4,294,967,295 bytes, because you can have files of zero length). This means that you cannot copy a file that is larger than 4 GB to any plain-FAT volume. This means that past 1803 the WIM file is TOO LARGE for a FAT32 flash drive.

Alternatives
You can use exFAT or NTFS on newer models, however older systems are NOT able to boot from external boot media using NTFS.

For these models it cannot be exfat and larger than 32 gigs or usb 3.X drive.

The WIM file for WINDOWS 1809 and 1903 and 1909 are TOO LARGE for FAT32.

PCI-E M2 Sata is not native to windows for many vendors.  Fixing the BCD may also be required as may be safe mode and use of diskpart.

You have to install F6 mass storage Drivers aka PRE INSTALL drivers or it WILL NOT see the drive.

You CANNOT point to an EXE or ZIP or Cab file it must be extracted to the USB flash.

Download the Media Creation Tool from Microsoft

(www.microsoft.com/.../windows10)

and use that to create the bootable Windows installation disk.

Thank you! It was set as NTFS unti lI saw this and now I can boot with UEFI now.

I Recommend to try other flash drive.

Since Windows 10 v1909 the ISO is 5GiB and there is a file it's more than 4GiB and FAT32 only support upto 4GiB, if i create a USB Bootable disk using NTFS it's not working, any solution?

Thank you for the explanation and links, @speedstep I was finally able to create a bootable thumb drive with the Windows 10 1909 Pro ISO that my e7270 recognized!

However, after installing 1909, the BIOS/UEFI doesn't recognize the M.2 SATA SSD.  It's flat out not visible in the configurations.  Do you have any idea why this might be?  I have tried updating the BIOS to the most recent, rolling back to earlier ones, and several in between, with no change.  The M.2 box is checked as one of the drive types available.  But in system configuration it's not listed. 

I finally got it to work!  I ran the Dell pre-boot system assessment, and the M.2 checked out OK.  So I compared the boot sequence in this laptop to a known good one.  I ended up having to manually add a boot option.  So in case anyone else runs into this, in the BIOS/UEFI, under Settings\General\Boot Sequence, click Add Boot Option. Pick the File System List that includes, anywhere in that string, the Sata SSD (the Latitude e7270 M.2 is SATA, not PCIe).  Click the ... to the right of File Name, and navigate to this:  \EFI\Microsoft\Boot\bootmgfw.efi  Give the boot option a name and click Ok.  Pick the boot option you just created as the first in the boot sequence.  Apply, and exit. It took extra long to boot up that first time, but I finally got the the initial Windows setup and it's working great!

PCI-E M2 Sata is not native to windows for many vendors.  Fixing the BCD may also be required as may be safe mode and use of diskpart.
