For those wondering why it\u2019s so bloody difficult to boot from a thumb drive with Windows 8 or Windows 10.<\/p><\/blockquote>\n

One reason: Microsoft is trying to protect you from yourself.<\/p>\n

That said, a caveat is in order. The following procedures are documented from testing with an ASUS Model X200M (laptop) running Windows 8.1. Your BIOS screen may differ as may the keys required to access the BIOS and the boot menu.<\/p>\n

Park the USB<\/h2>\n

Since the procedures involve restarting the computer and pressing keys to intercept the automagic boot from the hard drive, it is best to prepare by inserting your bootable thumb drive in an available USB port ahead of time, rather than scrambling to plug it in during the boot process.<\/p>\n

As Needed<\/h2>\n

The following procedure is conditional, based on the current settings for the two specified options. Once these changes are made in the bios, they will be retained until such time as they are again changed, whether deliberately, by accident, or through failure of the battery supplying charge to the CMOS. If you have already made these changes, move to the next section, \u201cEvery Time<\/strong>\u201d.<\/p>\n

    \n
  1. From powered down state, turn on the power OR, if already in Windows, choose Shut Down<\/strong>, Restart<\/strong>.<\/li>\n
  2. Then immediately press and hold the F2<\/strong> key or Del<\/strong>(ete) key (to enter the BIOS settings).<\/li>\n
  3. When the BIOS settings page appears, go to the \u201cBoot<\/strong>\u201d tab (press right-arrow key twice).<\/li>\n
  4. From the \u201cBoot<\/strong>\u201d tab, under \u201cBoot Configuration<\/strong>\u201d, check the setting for \u201cLaunch CSM<\/strong>\u201d. If it is set to \u201cDisabled<\/strong>\u201d, press the Enter<\/strong> key, to change it. If it is already set to \u201cEnabled<\/strong>\u201d, skip to step 7<\/strong>.<\/li>\n
  5. Choose the setting \u201cEnabled<\/strong>\u201d (up- or down-arrow key).<\/li>\n
  6. Press the Enter<\/strong> key.<\/li>\n
  7. Go to the \u201cSecurity<\/strong>\u201d tab (press right-arrow key once).<\/li>\n
  8. On the \u201cSecurity<\/strong>\u201d tab, at the bottom, choose \u201cSecure Boot Menu<\/strong>\u201d (press up-arrow key once).<\/li>\n
  9. Press the Enter<\/strong> key.<\/li>\n
  10. If it is set to \u201cEnabled<\/strong>\u201d, press the Enter<\/strong> key, otherwise skip to step 13<\/strong>.<\/li>\n
  11. Change the setting for \u201cSecure Boot<\/strong>\u201d to \u201cDisabled<\/strong>\u201d (up- or down-arrow key).<\/li>\n
  12. Press the Enter<\/strong> key.<\/li>\n
  13. If you changed either setting, press the F10<\/strong> key, and then the Enter<\/strong> key, to save changes and exit. Otherwise, just press the Esc<\/strong> key twice, and then the Enter<\/strong> key, to exit without saving changes.<\/li>\n
  14. Press and hold the Esc<\/strong> key, as the computer restarts, to access the Boot<\/strong> menu. However, see the \u201cNOTE<\/strong>\u201d, below.<\/li>\n<\/ol>\n

    Every Time<\/h2>\n

    The second part is performed each time booting from USB drive.<\/p>\n

    Presuming that you have performed the one-time procedure above, and Launch CSM<\/strong> has already been set to Enabled<\/strong>, and Secure Boot<\/strong> has already been set to Disabled<\/strong>, and that your bootable USB flash drive is already inserted in an available USB port, on power up or restart, press and hold the Esc<\/strong> key to access the Boot<\/strong> menu.<\/p>\n

    NOTE:<\/strong> Sometimes, on a restart, particularly from the BIOS settings, the computer will ignore the pressed Esc<\/strong> key and boot into Windows anyway, in which case, release the Esc<\/strong> key, choose shut-down, restart, and try it again, pressing the Esc<\/strong> key as soon as the blue \u201cRestarting<\/strong>\u201d screen appears and hold it down until the boot menu appears.<\/p><\/blockquote>\n

    When presented with the Boot<\/strong> menu (\u201cPlease select boot device:<\/strong>\u201d), you will typically see two entries indicating your USB bootable drive, one prefaced with \u201cUEFI:<\/strong>\u201d. Choose the other one, and press the Enter<\/strong> key.<\/p>\n
