What is the capacity of this USB drive? Which feature did you use to create the portable Windows? 'ISO/CDROM to USB' or 'Physical To USB'?
If you are using 'Physical To USB', WinToUSB will copy all the files in source boot partition (Usually C: ) to the destination USB drive, so the destination USB drive must be larger than the used space on source boot partition, and WinToUSB requires that the destination boot partition must be 20% larger than the used space on source boot partition. In such case, you need a larger USB drive.
