If you have an Acer desktop or Acer laptop, these are the steps you should follow to properly disable Secure Boot in Acer laptops.
If you are trying to install a Linux operating system on your Acer laptop, first you need to turn off secure boot for some distributions. Otherwise, the Secure Boot feature will block the installation due to not recognizing the boot-time software. This is applicable to any other software that runs at boot-time, like firmware drives and EFI applications. Thankfully, it is really easy to disable secure boot in Acer laptops.

What is Secure Boot?
Most modern desktops and laptops nowadays come with Secure Boot enabled. The Secure Boot feature is an effective security feature that only allows OEM (Original Equipment Manufacturer) trusted boot-time software.
When you turn on your laptop, Secure Boot will check every piece of software that runs at boot time. This includes firmware drivers, operating systems, EFI applications, etc. If a software doesn't pass all the tests, it will be considered not trusted and blocked from running. As you can guess, this is an effective countermeasure for virus and malware that run at boot time.
However, there might be situations where you are trying to run legitimate software but Secure Boot is blocking it. For example, when the Secure Boot is enabled, you cannot install some Linux distributions. In those kinds of cases, you have to disable the secure boot feature by following the steps shown above.
