Security Boot Linux

Hello everyone, I would like to touch on the subject of the new PCs and Laptops that are coming to the market, all with windows 8 pre-installed and with Security Boot.

This makes it difficult for us to have another Operating System (GNU / Linux for example) installed on the PC or Laptop, but do not worry there is already a solution (I do not know if it is the best or most appropriate but so far it is the only one there is ).

You should do what follows at your own risk. We are not responsible for data loss or damage to your HDD

It's simple, you just have to enter the BIOS and disable Fast Boot and then boot from the USB memory or CD in UEFI mode and problem solved.

Secure Boot

After you install the other system (GNU / Linux), if there are problems accessing our OS, we have to make use of Boot-Repair.

    Let's see, does shim not even work ?, which is what Ubuntu and Fedora bring, if I'm not mistaken.

    Good friend

    Could you explain a bit about the Secure Boot and what are the advantages of activating or deactivating it?

    1.    st0rmt4il said

      Advantages: You can install any other OS that is not from the Microsoft environment or world.

      Cons: As the author said in the main post, you run the risk of some anomaly in your HDD of your PC or Laptop.

    It is not more appropriate to look for a PC or Laptop free of operating system? So "virgin" I bought my laptop. I put what I want ...

      The point is, it's not always easy to find a "virgin" laptop, at least not here in the US. For that the most economical and feasible would be a custom desktop build

    Do not take it the wrong way but I see your article too brief.

    It is true that the Wintel alliance is still very strong, I estimate that 90% -95% of the PCs that go on the market have Windows pre-installed, but I have also noticed an upward trend of manufacturers opting to provide a second option. If ELAV and Kzkg allow me, here I talk about the subject:
    And Chromebooks were not mentioned, which in the case of the Pixel allows the easy installation of Ubuntu, Mint, etc.

    1.    diazepan said

      The case of Chromebooks is special because they use Coreboot, a Free BIOS

    From what I saw on my ga h61ma d3v board, the uefi, secure boot or bios mode, all three are selectable, and don't worry, no data is lost by deactivating the fast boot.

    It may be that you install Debian with Secure Boot with the following manual:

      To tell the truth, I deny my own article …… machine never had uefi. What I had was a bad partitioning. I just didn't realize it back then.

        We are the same, because also when I publish like crazy I just realize that I have just made blunders.

    Well, personally, on the subject of the desktop computer I had no problem because I configured a clone computer to my measure and as I wanted and then I installed the Linux that I wanted.

    Now if I had to buy a laptop, I would not know what to do, although I know that here in Spain there are also stores that sell them free of the operating system. Although I don't know what stores those might be.

    NO UEFIBoot = Bye Bye Mocosoft
    Welcome GNU / Linux

    It is true that Mocosoft is a tyranny with its SecureBoot shit that in the end does not protect anything at all

    1.    ratakill said

      No bro no bye bye Microsoft, they have a lot of power and market, I at least live in the US and the main PC stores are called Tiger Direct and Best Buy and they all already sell you Windows 8 pre-installed I asked their technicians and the reason is that they have a contract with microsost that they can only sell PC and laptop with their system if they do it with other OS they demand them. I think that rather Micrososft what they want to do is like to have a control and they want the linux to pay them like the companies that install android on their phones do.

      1.    pandev92 said

        Well, just delete windows 8, and install linux or if you hurry me to osx XD, and deactivate the secure boot, nothing more.

          Although turning your PC into a Hackintosh should be seen if the video card supports the 256 MB that it should have at least to at least work with the Aqua interface in a decent way, and lately, OSX86 like iAtkos only release their versions for motherboards 64-bit Intel and not with AMD.

          Anyway, I would rather install OpenBSD with KDE instead of turning my PC into a Hackintosh.

          1.    pandev92 said

            I do not advise anyone to use osx with a card with less than 512 mb xddd of video, much less use osx with an amd ... it will never be the same.
            About osx, I was just saying it, because it has some programs that are also in windows, I don't say anything about openbsd, because therefore, it doesn't have anything other than linux has.

            @ pandev92

            When I tested a MacBook, I was amazed by the visual and functional simplicity of the Aqua interface of the OSX, in addition that most of the programs that run in OSX run without problems (except the Adobe Flash Player, which seems to have problems with the interface when executing). However, its GUI which is Aqua is horribly heavy (and those who used Windows Vista complained about a measly 128 MB of video consumed by the Aero not including the overflows caused by the explorer that added another 128 MB of processing and still it does not reach what that interface consumes) and therefore, I would think of buying a cheap MacBook and not torturing my PC by wanting to turn it into a Hackintosh.

            As for OpenBSD, I'm just getting started. I must admit that the OpenBSD installer in the form of a form is quite simple and useful, and it could also be the perfect fit for Arch (although for this installer to be voluntary, it would only be enough to type in the terminal "archsetup" and thus the hypothetical installer helps us to install the system through this form with the name of each application and process that is going to be carried out).

            PS: Although OSX is considered the weakest BSD distro there is, there is a horde of fanboys that continue to use that system. I don't hate him or hold a grudge against him, I'm just being neutral and avoiding being a fanboy.

            PD2: But if it is Unix, it is Unix. Still, the management of applications in OSX without a console seems to me the most pleasant that I could have found.

    I just recently tried to remove the uefi from a friend's pc that had windows 8 installed with that, but I didn't deactivate it and everything and I don't know what happened, and I even passed it so that the boot order was first the cd-rom and not the one with the hard drive, I tease to do that, let's see what happens when I try again, thanks anyway!

    1.    ratakill said

      It depends on what you want, you can access this link and see the options you have (this is in the case of ubuntu) -> Here is well argued and documented everything regarding uefi and security boot, you can install it in uefi mode or not, it all depends on the manufacturer.

    I had to deactivate the «Legacy Mode» (I don't know what it will do), because I had also deactivated the Secure Boot and it didn't work for me. So if you see the legacy mode option out there, remember to disable it as well.

  12.   Willians vivanco said

    They should be glad to have the possibility at the BIOS level to disable the fucking UEFI ... When the damn technology started, the idea was that you had to swallow it all and suck it off.
    My new notebook came with Windows 8 and to install Debian, I had to do the additional step of going through the BIOS and disabling the UEFI.

  13.   Rini said

    The truth is that this system does not finish working for me (although the post is appreciated !!)

    If I disable Secure Boot and UEFI enabled, I can boot from USB, but then the laptop tells me "Operating system not found". I have then tried installing Debian on a partition in Legacy Mode. The result is to have both windows and Debian at the same time, but having to change the config. BIOS every time you want to change OS.

    That is, having to go to the BIOS and put it in "legacy" mode if I want to enter Debian, or in UEFI if I want Windows instead ...

    Wow, a bargain ^^ »

      You can install linux with uefi or without it, in case you want it with uefi you deactivate only the fast boot and leave the secure boot active and create a normal partition for the linux then boot for your usb or CD / DVD as you want, when it comes out The option to install or test linux in the boot options you add "nomodeset", and some time you have installed your linux, the grub will recognize windows 8 but it will not let you boot so you will have to run from the boot-repair console from linux, I will prepare a more detailed post about this, greetings

      1.    Rini said

        Thanks for the answer, I'll be attentive for that post! (Although I don't have anything like that of fastboot)

    As I was seeing in some posts on the dual boot issue, they advise installing a 64-bit system that supports uefi (debian, ubuntu, opensuse ...) and installing the boot on a separate partition and then from "wintendo" using the EasyBCD tool to create it an entry for Linux. With all this supposedly from the Windos boot menu we can start any of the systems, I have not checked this method but I will soon.
