I have a Toshiba Satellite L55-A5284 laptop with a Windows 8.1 home edition installed. I would like to configure it in a such a manner which would prevent one from loading/installing Linux from a USB drive. I do have UEFI secure boot enabled, however, I am still able to load Linux Mint from a USB drive. What other steps can I take to 'seal off' this Windows machine?

Thank you

  • You accepted an answer, so it's great that your own needs were satisfied. However, the site is a knowledge base, with a purpose of helping others with similar problems. Your question is pretty ambiguous about the degree and type of protection requested. Is this just so that you don't accidentally install Linux yourself, so you need some hoops to jump through? Is this in a shared environment, and you want to prevent a knowledgeable person from changing your machine? How knowledgeable and committed a person do you need to prevent from changing your system?

  1. Add admin and system password
  2. Choose only HDD as the bootable media remove usb and other options or move them after HDD if no option to remove

Referring Disable USB drives during boot up?

Now with this setting nobody can boot from other media except your HDD even that with your password

  • please elaborate: when you said 'lock... power on' with a password, how does one accomplish locking a 'power on' in Windows? when you wrote 'lock BIOS', did you mean with admin password or with system password? thanks

  • You should see system and bios password enable those and then disable usb boot can't elaborate further every bios is unique so you will have to look for those options
