Windows 10: Accidentally bricked a flash drive using media creation tool, help?

I was halfway through finishing making a bootable USB using the 1909 Media Creation Tool, when I closed the lid of my laptop.

Now, the flash drive isn't seen by:

• Media Creation Tool
• CMD as Administrator -> Diskpart
• Disk Management Tool
• Rufus
• Device manager
• A simple shut down and reboot
• UEFI-boot command prompt

I haven't tried any pre-boot alternatives (like an ubuntu live boot) to identify it, are there any options that I can use without having to have a second flash drive?

Failed Media Creation Tool attempt at bootable USB flash drive


Shawn, these are the steps being referred to that NavyLCDR posted. They work for both UEFI and MBR.

Here are the steps to create a standard Windows 10 USB flash drive:

1. Use the Media Creation Tool to download and save the ISO file to your hard drive.
2. Insert the USB flash drive.
3. Open a Administrator Command Prompt and enter: diskpart (if it isn't an administrator command prompt, it will ask for administrator permission).
4. list disk
5. select disk # <- replace # with the actual disk number of the USB flash drive
6. clean <- this will erase the disk selected above, make sure you selected the USB flash drive!
7. create part pri
8. format fs=fat32 quick
9. active
10. exit
11. exit - and if the first Command Prompt was not an Administrator Command Prompt, exit that one too.
11. Mount the ISO file saved by the Media Creation Tool. If you are using Windows 8 or 10, you only have to right click on it and click on mount. If you are using Windows 7, then you must use a program like WinCDEmu to mount the ISO file:
WinCDEmu - the easiest way to mount an ISO. And more...
12. Copy all the files and folders from the mounted ISO file to the USB flash drive.

That's as simple as it gets. Between steps 7 and 8 you can enter: "select part 1" without quotes - but it should not be necessary.
Between steps 8 and 9 you can enter: "assign" without quotes - but it should not be necessary.

 

Media Creation Tool question


Thanks Cerberus but Ive no problem downloading the Iso with the media creation tool. I don't think its the ISO that is the problem' I think the problem is when the Media Creation Tool is creating the bootable USB flash drive. So I think I can use the Media Creation Tool for that part...and as you say try something like Rufus to create the bootable USB flash drive

I still have this question though "The tutorial here says after going to the Microsoft site and selecting the Download Tool (Media Creation Tool) option that the Media Creation Tool should be save to the PC and run from there.
On Microsoft site the instructions are to Download the Tool and select Run (no saving to the PC). Is there a reason for saving it to the PC first as suggested on Tenforums?"

I was curious to see if others had encountered the issue I had with the Media Creation Tool. Ive never had a problem using it before
