If it was light blue, this method will not work. ![]() Use this method if you are interested in booting using UEFI, and if your System Rescue CD initial boot menu was black and white. ![]() Your new MBR partition table will now be written to your system disk. Write the parition table to disk: Command (m for help): w I/O size (minimum/optimal): 512 bytes / 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes Hex code (type L to list all codes): 82 ↵Ĭreate the root partition: Command (m for help): n ↵ Now we will use fdisk to create the MBR partition table and partitions: This output is also nothing to worry about, as the command still succeded: GPT data structures destroyed! You may now partition the disk using fdisk or This will make any existing partitions inaccessible! You are strongly cautioned and advised to backup any critical data before proceeding. You can poke around in your BIOS boot configuration and play with this. Your system may still support BIOS booting, but just be trying UEFI first. This means that you are ready to install Funtoo Linux to boot via UEFI. Principle 2 - New School If you can reliably boot System Rescue CD and it shows you an initial black and white menu - congratulations, your system is configured to support UEFI booting. In that case, see Principle 2, as your system may also support UEFI booting. So, go old-school and use BIOS booting, unless you have some reason to use UEFI, such as having a >2.2TB system disk. Principle 1 - Old School If you can reliably boot System Rescue CD and it shows you an initial light blue menu, you are booting the CD using the BIOS, and it's likely that you can thus boot Funtoo Linux using the BIOS. The big question is - which boot method should you use? Here's how to tell. We used to recommend a BIOS + GRUB (GPT) method but it is not consistently supported across a wide variety of hardware. We refer to this method as the UEFI + GRUB (GPT) method.Īnd yes, there are even more methods, some of which are documented on the Boot Methods page. Instead, we recommend using UEFI to boot GRUB, which in turn will load Linux. If you need to use UEFI to boot, we recommend not using the MBR at all for booting, as some systems support this, but others don't. It's the traditional method of setting up a PC-compatible system to boot Linux. The boot loader we will be using to load the Linux kernel in this guide is called GRUB, so we call this method the BIOS + GRUB (MBR) method. Our recommendation is still to go old-school unless you have reason not to. So, out of compassion for people who fall into this predicament, this Install Guide documents UEFI booting too. Another reason is that there are some so-called "PC" systems out there that don't support BIOS booting anymore, and force you to use UEFI to boot. If you have a system disk >2TB in size, then MBR partitions won't allow you to access all your storage. If your system disk is 2TB or smaller in size, it won't prevent you from using all of your disk's capacity, either.īut, there are some situations where the old-school method isn't optimal. ![]() It works and (except for rare cases) is universally supported. This Install Guide uses, and recommends, the old-school method of BIOS booting and using an MBR. Let's take a moment to review the options available to you for configuring a hard drive to boot Funtoo Linux. All of the sudden, we had a variety of options for installing and booting Linux systems, turning what once was a one-method-fits-all approach into something a lot more complex. Then, along came EFI and UEFI, which are new-style firmware designed to boot systems, along with GPT partition tables to define disk partitions on disks larger than 2.2TB. All of our desktops and servers had standard firmware called the "PC BIOS," all our hard drives used Master Boot Records at the beginning of the disk, where the PC BIOS would "look" to find boot loader code which would in turn load Linux, and our hard drives were partitioned into different regions using the standard MBR partition scheme. In earlier times, there was only one way to boot a PC-compatible computer. If you are an absolute beginner to Linux, you may be less confused if you skip to the next section, Which to Use?
