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.

This driver supports Samsung NVMe SSD 970 PRO, 970 EVO, 970 EVO Plus, 960 PRO, 960 EVO and 950 PRO.

Download the Media Creation Tool from Microsoft

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

and use that to create the bootable Windows installation disk.

I did that and windows still says that must be gpt partition. If it is an .iso file, how am I suppose to format as fat32 vs ntfs?

146562

Use 7zip to expand iso into a folder, run cmd as admin, use diskpart to clean, create primary partition, format fs=fat32 quick, set to active, exit, then, while still in CMD, xcopy  *.* /s  from that folder to your USB.

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?
