Boot from USB device

Boot your computer from a USB drive

In order to successfully boot your computer from a USB drive, you may need to ensure the following steps have been taken in the UEFI/BIOS configuration of the computer.  Each manufacturer and UEFI/BIOS can be different.

  • The best boot support will be available when you are using the latest system firmware for your device.
  • Native UEFI mode is preferred over BIOS emulation.
  • UEFI USB boot requires that USB disks should be have at least 4 gigabytes of capacity, the boot mode should be set to UEFI or UEFI native and not UEFI+CSM or UEFI Hybrid, and you may have to disable Fast Boot or Quick Boot on some systems.
  • Your USB boot drive should be formatted with the FAT32 file system.
  • Avoid USB 3.0 ports, as the boot support is better for USB 2.0 on many systems.
  • If you have trouble booting from USB, you may instead use the Lite touch ISO to create a bootable optical disc, then boot from an internal or external DVD drive.
  • Only if necessary, switch back to Legacy or BIOS emulation mode from UEFI mode.  This will slow boot times and disable options such as Secure Boot protection, but may be necessary on some older systems without updated firmware support.
  • Remember to enable the TPM and TPM options to enable volume encryption.
