WoeUSB creating bootable USB not working

Question

I am using Ubuntu 18.04, woeUsb, 15 GB usb3 Stick, windows 10 64Bit ISO to create bootable device. I found few tutorials how to do it, but I still get error.

• Installation failed!
• Exit code: 256

Log:

WoeUSB v@@WOEUSB_VERSION@@ ============================== Mounting source filesystem... Wiping all existing partition table and filesystem signatures in /dev/sda... wipefs: error: /dev/sda: probing initialization failed: No medium found The command "wipefs --all "${target_device}"" failed with exit status "1", program is prematurely aborted Unmounting and removing "/media/woeusb_source_1532252869_8362"... You may now safely detach the target device

I tried to format my USB several times but nothing worked. I used FAT32 format. Should I first convert it to NTFS?

Answer 1

I have the same issue and found the solution by unmounting USB drive in this way,

Go to the Disks and select your USB drive from the left side menu, and click on the icon shown in the below image to unmount USB.

Answer 2

The command line version of the tool works better in my experience:

woeusb --device Win10_1909_English_x64.iso /dev/sdX --target-filesystem NTFS

/dev/sdX might be different on your system such as sda sdb ..., make sure to check the device path using gparted or fdisk.

Make sure to set the filesystem to NTFS with --target-filesystem NTFS as FAT32 doesn't support large files.
