I cannot boot my Acer Aspire V5-471G from a bootable USB stick. Already altered the BIOS in a way that the USB has priority over HDD, but still nothing happens and Windows 8 boots normally from HDD. It's like the USB stick is not plugged into the laptop at all.

What should I do?

  • I never owned an Acer but from reading stories about attempts to install Linux I've learned that Acers often need UEFI password to enable trust for booting external devices. – user931000 Nov 23 '19 at 15:36

Boot into BIOS Setup and do the following (might not be exact for your BIOS):

  • In the Security tab, if Secure Boot is enabled, using your Arrow and Enter key, disable it or change it to "Setup Mode"
  • In the Boot tab, if UEFI mode is enabled, change it to Legacy Boot.

This should now show your USB drive as a bootable device.

Note that if Windows was installed with the BIOS in UEFI mode, then it may not boot in Legacy mode.

  • Is the reason for the downvote that this didn't work for you? – harrymc Nov 23 '19 at 21:15
