Optiplex 7010 won't boot windows 10 from usb

Microsoft prepared it. They took control of my laptop (not the affected computer) & did all that. It does though just present as an ISO. It that what it should be? 

Re: I got an ISO from Microsoft Support on a USB

you need a bootable usb that has Win 10 installation media, not a bootable usb with a copy of Win10.iso. Using Microsoft media creation tool to prepare the usb is a recommended way.

PS you may be able to reset admin password by motherboard password jumper.

Makes you wonder why, when I was back on with them today & said what I said above, they didn't say this was wrong. Lokk, many thanks, I'll try creating the bootable myself & will post on here if I have success. Again, very many thanks for your response - should have come here first  

This worked, many thanks. Have been chasing this for hours, Microsoft Support failed to support I'm afraid. Very much appreciated.

Should be NTFS I believe. not that I'm the expert

This was instructions I was given before Microsoft 'did it' themselves. 

CLEAN INSTALLATION STEPS
Here is a step-by-step process to perform a clean installation of windows on your computer.

To get started, you need an 8GB USB flash drive, kindly follow the instructions below to create the bootable media on the alternate PC.

Create a bootable USB
Prepare a USB (thumb drive/pen drive/flash drive) with at least 8GB of space. Any content on it will be deleted.
Format the USB, and make sure its file system is NTFS:
- Go to File Explorer > This PC
- Right-click on your USB drive > Format > Choose The error NTFS as File system > Start

1. Plug in the 8GB USB flash drive to the alternate PC and click the link provided to download the Media Creation Tool for Windows 10.

Download windows 10: https://www.microsoft.com/en-gb/software-download/windows10

2. Select "Download tool now" and select Run. You need to be an administrator to run this tool.
3. If you agree to the license terms, select Accept.
4. On the What do you want to do? page, select Create installation media for another PC, and then select Next.
5. Select the language, edition, and architecture (64-bit or 32-bit) for Windows 10.
6. Select which media you want to use: USB flash drive.
7. The tool will begin the download of the windows 10 ISO disk image after which comes to the media creation process. It will do this automatically.
8. Once completed, click "Finish" to close the setup. Your USB is ready for the installation

Once the USB flash drive has been made into a bootable media, unplug it from the alternate PC and plug it onto the faulty PC. Kindly follow these instructions to install windows on the faulty PC;

1. Reboot the PC into the WinRE
2. Choose "Troubleshoot" >> "Use a Device" >> EFI USB Device

OR

* Choose "Troubleshoot" >> Advanced Options" >> UEFI Firmware Settings
This will take you to the BIOS Menu Setup page for the faulty PC

Alternatively, you could reboot the PC directly into the BIOS Setup Utility page by pressing on ( Continuously tapping ) the BIOS hot key ( F2, F9, F12 - depending on the brand/manufacturer of the PC ) immediately after the machine lights up after firing it up with the power button.

Once on the BIOS Setup Utility page,
Use your arrow keys on your keyboard and navigate to the following tabs:
a. Security: Check for and disable "Secure Boot" if enabled. Also, check for and disable "Fast Boot" if present and enabled
b. Boot: Check for "Boot Priority Oder" or "Boot Order" or "Boot Options" ( they all mean the same depending on the PC's manufacturer ) and move the USB drive from its current position to the first position
c. Save and Exit: Select "Save and Exit" or press F10 for the same option to save changes
The PC would restart to begin Windows installation

3. The Windows logo will appear on the screen, this might be here for a while, if you see the animating dots, everything should be ok.
4. Select your Language, Time, and Keyboard method then click Next.
5. Click "Install now"
6. Enter a product key for windows 10 if you have one; if you don't just click on "I don't have a product key"
7. Select the right edition of Windows 10. Select either Windows 10 64-bit Home or Pro. Be sure of this before beginning the process
8. Wait while setup prepares to copy files then Accept the license terms then click Next
9. Click Custom: Install Windows only (advanced)
10. Once on the "where do you want to install windows page", from the multiple partitions, select the Primary partition then click Next.
11. Wait while Windows installs
12. Take out the USB drive once the PC restarts and wait till windows complete the installation till it asks you to set up your PC

I'm in the same boat at the moment. Tried booting from a pendrive, formatted to FAT32 and copied all the files/folders/bootables from the ISO image which I downloaded from the microsoft site.

The drive is detected in BIOS, but upon selection just get a fail to boot message.

Re: Tried booting from a USB drive, formatted to FAT32 and copied all the files/folders/bootables from the ISO image which I downloaded from the microsoft site.

manually copy and paste files in .iso is incorrect way to make a Windows 10 installation media.  

Using Microsoft media creation tool to prepare the usb is the correct way.

the tool will automatically erase everything present on USB and prepare a fresh clean bootable media.

PS another correct way is to burn a DVD using Microsoft media creation tool which asked you to choose option between USB vs DVD. 

PC can boot and install OS from either the correctly prepared USB or DVD when it detects a bootable media, but you cannot copy paste all the files from the DVD to a blank USB and think it would work.  That would not work.
