The new UEFI specification has changed the method a computer uses to boot its operating system. This has added challenges to running Linux on a PC which uses UEFI. Most/All desktops/laptops which have been preinstalled with Windows 8 now come with UEFI so we will need to deal with this. This guide will try and assist you in getting Linux up and running.

For here on out when we refer to Ubuntu 12.10 that also includes all its derivates (Kubuntu, Xubuntu, Linux Mint, etc.) The exception to this is when we talk about the Ubuntu remix edition Agen Judi Bola Obat Herbal Infeksi Lambung Dan Usus

When we talk about Windows 8 here we will assume it has been installed in UEFI mode, this is normally the case with a pre-installed version of Windows 8.

Warning on Samsung Laptops

Obat Herbal Pengencer Darah Kental A number of users have reported that making changes to a Samsung laptop's UEFI boot options has caused a complete brick of the laptop. Extreme care needs to be taken on these laptop, I would recommend not installing Linux until a proper solution is found.

Dual Booting with Windows 8 vs Standalone Installation

If you are not planning to run Windows 8 alongside your Linux installation then you will have an easier time installing Linux. Dual-Booting Windows 8 does add extra challenges. In this guide we will cover methods of installing Linux dual-booting with Windows 8 and also cover a standalone Linux installation. Windows 7 does not have the same installation challenges that Windows 8 provides and dual-boot is usually handled by the Linux installer.

Secure Boot

Obat Herbal Pembuang Lemak Dalam Darah Secure boot is a new feature of UEFI, its purpose is to allow only signed bootloaders to boot the system. If you are not going to be running Windows 8 it is recommended, if you can, to turn off this feature in your computers UEFI settings. However we will try and deal with Secure Boot if you require it to be turned on.

At time of writing, I only know of two Linux distributions which support Secure Boot, Ubuntu 12.10 and Fedora 18. I will experiment with other distributions in the future.

Turning off Secure Boot

If you wish to use a Linux distributions which doesn't support Secure Boot then you will need to turn it off in your UEFI settings. There is no standard way of doing this so it's not possible to explain the process here, but typically there is an option for disabling it within your computers UEFI settings. Check your computers manual for details.
===== Intalling in UEFI vs BIOS mode =====Cara Mengobati Flu Singapura Pada Bayi
Some computers allow you to install the operating system in either UEFI or BIOS/Legacy mode. In this guide we will try and cover both methods, but keep in mind that if your computer was pre-installed with Windows 8 and plan to dual boot then you will need to install in UEFI mode.

Turning off UEFI boot

If you do not wish to use Windows 8 then you may be able to turn off UEFI booting and switch to BIOS/Legacy booting. There is no standard way of doing this so it's not possible to explain the process here, but typically there is an option to enable/disable certain types of booting from within your computers UEFI settings. Look for an option relating to booting methods. Unfortunately not all computers allow you to switch modes, some newer computers may only support UEFI booting.

Booting your Linux installation media in UEFI mode

How you boot your Linux installation media will dicate how the operating system in Agen Judi Online Terpercaya installed, so if you intend to use UEFI make sure you boot the installation media in UEFI mode. Depending on your UEFI implementation there are a few ways of booting from your Linux installation media. I would recommend when you are going to boot from your installation media that you should press the key which gives you the boot options menu. Unfortunately there is no standard key for this so see your computers manual for details. As a quick example, on a HP laptop it is normally F9. Obat Herbal Untuk Gondok Dalam

If you plan to dual boot with Windows it is important to install Linux in the same mode as the Windows installation. A pre-installed Windows 8 installation will have been installed using UEFI so you need to ensure you boot your Linux installation media in that mode as well.

When you see the boot menu you should see a list of devices you can boot from. If your computer is able to boot via both UEFI and BIOS/Legacy mode you will likely see multiple options for the same device, but usually the UEFI option starts with UEFI:. For example, for your optical drive you may have two options, Toshiba Optical Drive and UEFI: Toshiba Optical Drive. Select the UEFI option to boot in UEFI mode and the non-UEFI option to boot in BIOS/Legacy mode. If your computer doesn't support booting from UEFI mode then you may not see UEFI: options, however if the drive you want to boot from is listed then it will boot with UEFI mode.

Now it's possible that while you can see UEFI: options for your hard drive there may not be one for your optical drive. In this case your computer may not be able to boot via DVD in UEFI mode or may not be able to boot via DVD at all. In this case a Live USB stick may work, see the next section.

Dealing with being unable to boot via DVD

While some computers allow you to boot in UEFI mode via a DVD I've found that some computer don't. In this case I have found that creating a Live USB to boot from give you the ability to use UEFI. The LinuxLive USB Creator works very well for this purpose so if you can't boot via DVD try this option. Just create a Live USB stick and try to boot your computer from it. Because the computer sees the USB stick as another hard drive you may have better luck in booting from that, I have found a few HP laptops that required this trick.

Installing Ubuntu 12.10 with UEFI

There is a special remix version of Ubuntu 12.10 called Ubuntu 12.10 Secure Remix. This is a slightly modified Ubuntu DVD/ISO which includes some extra tools to help with booting issues. While not essential, I would recommend using this version when doing a UEFI install.

If you are planning to use one of the Ubuntu derivates (KUbuntu, Linux Mint, etc.) then you wont be able to use this DVD to install, but the tools are still useful so it may be helpful to you anyway.

After Ubuntu Linux 12.10 installation still can not boot

After installing Ubuntu with UEFI you may find that your computer doesn't boot, still only boots into Windows or only boots into Linux when you were wanting a dual-boot install. In this case you can make use of the Boot-Repair program.

The Boot-Repair program comes with the Remix edition of Ubuntu 12.10 so you will need to boot with your installation media again and then run the program. If you aren't using the Remix edition then boot from your installation media again, open a terminal and enter the following two lines:

sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update
sudo apt-get install -y boot-repair && (sudo boot-repair &)

You should now have the Boot-Repair program loaded. In pretty much all cases all you need to do is press the Recommended repair option and that will take care of everything for you.

Now just reboot your machine and attempt to boot normally, hopefully it has worked properly for you.

After Fedora 18 installation still can not boot

After installing Fedora with UEFI you may find that your computer doesn't boot, still only boots into Windows or only boots into Linux when you were wanting a dual-boot install. In this case you can make use of the Boot-Repair program.

Boot-Repair is not included with Fedora 18 so needs to be obtained separately. Probably the best way of achieving this is to use the Ubuntu 12.10 Secure Remix DVD. While this is an Ubuntu DVD the Boot-Repair program includes support for Fedora 18 as well. Just boot the DVD in UEFI mode (or create a LiveUSB if your computer requires it for UEFI booting) and run the Boot-Repair program. In pretty much all cases all you need to do is press the Recommended repair option and that will take care of everything for you.

Now just reboot your machine and attempt to boot normally, hopefully it has worked properly for you.

Booting was OK but is no longer working properly

It appear some recent Windows 8 updates have caused the UEFI setting to revert, preventing Linux from booting. In this case just follow the instructions above for using the Boot-Repair program and it should get you up and running again.

openSUSE-12.3 notes on UEFI

The openSUSE-12.3 release notes provide details on some quirks wrt openSUSE-12.3 UEFI installation.

Cara Mengobati Gondok Beracun Secara Alami

For machines in UEFI mode with secure boot enabled using openSUSE-12.3, the YaST installer does not automatically detect if the machine has secure boot enabled and will therefore install an unsigned bootloader by default. But the unsigned bootloader will not be accepted by the firmware. To have a signed bootloader installed the option “Enable Secure Boot” has to be manually enabled in the YaST installer.

For machines in UEFI mode when using the installer on the live medium, YaST installer does not detect UEFI mode and therefore installs the legacy bootloader. This results in a not bootable system. The bootloader has to be switched from grub2 to grub2-efi manually in the YaST installer. Obat Pelangsing Yang Aman Untuk Lambung

For machines in UEFI mode the double signed shim on openSUSE 12.3 medium may be rejected by future firmwares. If the openSUSE 12.3 medium does not boot on future secure boot enabled hardware, temporarily disable secure boot, install openSUSE and apply all online updates to get an updated shim. After installing all updates secure boot can be turned on again. Pengobatan Herbal Untuk Menghilangkan Benjolan Di Bibir

For openSUSE-12.3 installations in UEFI mode, in the YaST installer partitioning proposal when checking the option to use LVM (which is required for full disk encryption) YaST does not create a separate /boot partition. That means kernel and initrd end up in the (potentially encrypted) LVM container, inaccessible to the boot loader. To get full disk encryption when using UEFI, partitioning has to be done manually.

Conclusion

Cara Alami Untuk Mengobati Jantung Bocor UEFI is still a pain to setup properly and is complicated even more with Secure Boot.
