I followed the same process which mentioned in below link to create USB stick for windows:
But WinUSB throws following error while syncing:
Try dd command.
The dd command copies a file, converting the format of the data in the process, according to the operands specified.
if=FILE -- Read from file instead of stdin.
of=FILE -- Write to file instead of stdout
bs=BYTES -- Read and write bytes at a time.
count=BLOCKS -- Copy only input blocks.
sync -- Use synchronized I/O for metadata.
Open a terminal.
sudo -i fdisk -l (Identify your usb-stick, suppose is /dev/sdb) dd if=/path-to-your-iso/Win_7_64Bit.iso of=/dev/sdb bs=4M; sync
Note: Always clearly identify the usb-stick with fdisk -l command, improperly entering the wrong values could inadvertently overwrite the data on the hard drive.
