Windows 10 To Go Image not booting on Computer with UEFI

Hi,

I'm trying to make a Windows To Go image for my PC repair business using Rufus and a Windows 10 Pro ISO from MS Techbench. It boots perfectly fine on most computers except one. The computer I am trying to boot off is running Windows 8.1 with a UEFI bios. It's got a weird "EFI File Navigator" which is a pain in my rear end. When I try booting from it, it gives me an error. A picture of which is attached.


Any ideas?

Thanks.

Convert the partition to FAT32?

Rufus creates a FAT32 partition (which includes a Linux NTFS driver and IIRC both x86 and x64 versions) for booting on EFI and an NTFS partition that contains the installation files. Seems that the firmware on that PC may not support that driver.

Perhaps try creating WTG with WinToUSB

I looked into the issue, going as far as communicating with the developer of Rufus himself, and apparently the HP UEFI BIOS doesn't sit well with NTFS bootable drives, and he's looking into the issue. I will otherwise attempt to use WinToUSB, but I'm not sure if it would be affected by the issue as well.

Again, why not just convert the existing NTFS partition to FAT32?

In order to use WTG you have to be able to boot the USB in Legacy Mode (Not UEFI)
May have to enable legacy support in BIOS

Unless you purchase an Sandisk Extreme USB which supports partitioning
it supports partitioning because unlike a standard USB it is not flagged as removable, but rather as a fixed disk usb..

the other way and a better option in my view - is the use an external HDD and an adapter...

Actually Sandisk Extreme drives no longer support partioning like an official WTG drive.

You can use EasyUEFI - The EasyUEFI Development Team to install windows 10 for UEFI PCs if a WTG flash drive or any external USB harddrive/ssd.

FAT32 made no difference on the machine. It worked on other machines though

I guess that has changed since they where about a third of the price as certified sticks...

Michael, your error is directly related to Rufus...use a different method and if you still get one then we can handle those as generic - The Rufus dev is good but I don't think he will be able to solve this issue as it's a bit unique...
