Install boot manager to empty HD for booting into installation medium

I have a laptop where I’m locked out of the bios and the boot device is fixed to the internal hard drive. I would like to install a new OS on this laptop and was wondering if the following would work:

  1. Take out the hard drive from the laptop
  2. Install a boot manager on the HD using a different computer
  3. re-install the hard drive into the laptop
  4. boot into the boot manager and select an installation medium (USB or others) to continue booting from
  5. install the new OS on the HD

Would this work? How would I do step #2 and which software could I use?
