How to erase windows 10 off of boot USB drive

[garrettk4]

Ok so I used the media creation tool to put win 10 on my flash drive. It didn't finish and said there was an error. Now I want to know how to get my flash drive back to normal. I've tried formatting, deleting it won't let me use the drive again. Its a 64gb drive so I need it bad...

Hi,

When you format your USB drive make sure it's set as FAT32. If it's set to another format it won't be read by your PC.

Ok so I'm in disk management. It shows my 64gb flash drive as two partitions. 32gb is usable but the other 26 I cannot format shrink, extend, nothing I cant do crap with it. I need those 26gbs.

your msaking things too difficult ffor yourself. just go into "my computer" or if on windows 8 and up its called "this PC" once in there right click on the USB drive and then left click format. when it comes up just make sure its set to FAT32, make sure quick format is checked off and click start.

I've done that, it still says 31.9gb and the system volume folder still exists

Windows can only read one partition in USB flash drives.. to format the undetected partition, you have to delete the detected partition so the whole 64GB are joined. You could also try a third party Partition Manager which have more functions than the Windows disk manager and the inaccessible partition may be more accessible.

If the undetected partition has a file system, it should be detected after deleting the detected one, then extend the remaining partition to cover the whole 64GB.
