How to use WinToUSB to install Windows onto a USB drive as portable Windows?

1. Connect the destination external hard drive or flash drive to the computer with an installed copy of WinToUSB.

2. Please use the following guidelines to prepare the partitions if you are using an external hard drive to create Windows To Go. You do not need to perform this step if you are using a USB flash drive to create Windows To Go, WinToUSB will help you to format the USB flash drive in setp 6.

  • Booting both BIOS-based and UEFI-based computers (Recommended): Please convert the USB drive to MBR partition scheme and create the system and boot partitions. The system partition must be FAT32 format and the boot partition must be NTFS format.
  • Booting BIOS-based computers: Please convert the USB drive to MBR partition scheme and create the system and boot partitions. The system partition can be FAT32 or NTFS format and the boot partition must be NTFS format. The system partition and boot partition can be the same partition.
  • Booting UEFI-based computers: Please convert the USB drive to GPT partition scheme and create the EFI system partition (ESP) and boot partition. The EFI system partition must be FAT32 format and the boot partition must be NTFS format.

Tips:

  1. Both the system and boot partition must be primary partition, and we recommend using Windows built-in Disk Management (diskmgmt.msc) to partition and format the disk. If you use a third-party partitioning tool to format the partitions, Windows may not boot properly.
  2. The destination boot partition must be a NTFS partition and at least 14 GB.
  3. The destination system partition must be a NTFS/FAT32 partition. If the destination system partition is a FAT32 partition, then it must be greater than or equal to 40 MB and less than or equal to 32 GB. (The recommended size is 100 – 500 MB.)
  4. If you have formatted the wrong USB drive, you can use our Free Data Recovery Software Hasleo Data Recovery to recover your lost files.
