The WIM file for WINDOWS 1 are TOO LARGE for FAT32. Use Windows USB/DVD Download Tool to create a bootable Windows 10. Use mediacreationtool just to download the ISO. I download a bios and used rufus to make a bootable usb.

Sometimes, you'll find that the drive letter of your USB drive is the same as the partition on your PC. Windows Media Creation Tool Can Not Detect USB - Microsoft Community TO TonyIsntGood Created on FebruWindows Media Creation Tool Can Not Detect USB My main computer, which runs windows 8.1 pro, crashed and is currently stuck in an auto repair loop displaying 'Log files D:V/windows/system32/logfiles/srt/srttrail.txt. Wait for a few minutes and then install the USB device properly. Right-click and click the 'Uninstall Device' option. You can use exFAT or NTFS on newer models, however older systems are NOT able to boot from external boot media using NTFS.įor these models it cannot be exfat and larger than 32 gigs or usb 3.X drive. I had to end up using a third-party tool called rufus. Check out for your USB device that is not being detected. This means that past 1803 the WIM file is TOO LARGE for a FAT32 flash drive. This means that you cannot copy a file that is larger than 4 GB to any plain-FAT volume.


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). 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. This is why I recommend using USB 2.0 optical drive and OEM system builder DVD for reinstall. The media must be at least 16 gigs and not larger than 32 gigs and USB 2.0.
