Ubuntu has a signed boot loader and kernel by default, so it should work fine with Secure Boot. However, if you need to install DKMS modules (3rd party kernel modules that need to get compiled on your machine), these do not have a signature, and thus can not be used together with Secure Boot.
Then, does ubuntu version 14 support secure boot?
The most common answer is: Windows 7 in UEFI does not support secure boot, Windows 8 and Linux Ubuntu verson 14 do.
Ubuntu Core supports both hardware and software root of trust for secure boot. Security admins can create and store the digital keys used to validate the boot sequence in either a secure element, a TPM device or a software TEE.
You might be asking “What is Ubuntu Core secure boot?”
Ubuntu Core abstracts the root of trust implementation for its secure boot process. As a consequence, Ubuntu Core secure boot can be enabled for both ARM and x86 So, and cs. Secure boot is available out of the box on certified devices, like the Raspberry Pi, at no additional cost.
How does UEFI Secure Boot work on Ubuntu?
On Ubuntu, all pre-built binaries intended to be loaded as part of the boot process, with the exception of the initrd image, are signed by Canonical’s UEFI certificate, which itself is implicitly trusted by being embedded in the shim loader, itself signed by Microsoft.
Then, why does Linux use Microsoft secure boot?
This means we can generally rely on the firmware on these systems to trust binaries that are signed by Microsoft, and the Linux community heavily relies on this assumption for Secure Boot to work. This is the same process used by Red Hat and SUSE, for instance.
Does ubuntu support uefi?
Ubuntu 20.04 supports UEFI firmware and can boot on PCs with secure boot enabled. So, you can install Ubuntu 20.04 on UEFI systems and Legacy BIOS systems without any problems. Download Ubuntu 20.04 LTS desktop iso image from the Ubuntu website. Burn the downloaded Ubuntu OS image to a DVD using your favorite DVD burner in Windows.
( Ubuntu32bit cannot be easily installed in UEFI mode. This is a problem if 32-bit EFI is the only way your computer can boot, e. g. if you have a modern Intel Atom based laptop . In this case, you will need a complicated work-around .).
The “UEFI: USB” line allows to boot the Ubuntu live. USB in EFI mode. Here is a 2nd example of BIOS, simpler, where the “Boot Mode” parameter allows one to choose the boot mode (“UEFI” or “Legacy”) for all media (hard disk, CD, USB ) at the same time.
Why can’t I install Ubuntu on my computer?
Practice usually follows theory, but sometimes it doesn’t — some computers just don’t seem to get along well with Shim (the program that Ubuntu uses to work with Secure Boot). A Secure Boot problem is almost certain to manifest itself as an inability to even begin to boot — either the Ubuntu installer or the Ubuntu system once it’s installed.
