Many years later, I’m often surprised by how few people are aware of it, and how many people still struggle with GRUB for booting their Linux systems.GRUB is the default on all major Linux distributions in order to keep compatibility with older computers that don’t have EFI. Windows - Microsoft Windows Default value: osx usegraphicsfor linux, windows Which non-bootloader tools to show on the tools line, and in what order to display them: shell - the EFI shell (requires external program see rEFInd documentation for details)I came across rEFInd five years ago, and it was one of those things that solved a lot of headaches for me. I tried a bootable ubuntu usb and booted it from rEFInd, and ran the 'try ubuntu' just fine. If you use GRUB for booting multiple distributions and have never heard of rEFInd then this article is for you.Then I installed rEFInd and tried booting from the windows partition, bootable Windows 7 Pro 64bit usb, and a bootable Windows 10 Home Premium 64bit usb but still got the blinking cursor when booting. This script automatically copies rEFInds files to your ESP or other target location and makes changes to your firmwares NVRAM settings so that rEFInd will start the next time you boot.The rEFInd is a boot manager that works on EFI and UEFI systems, capable of booting Windows, Mac OS X, and Linux on the local computer, as well as boot from a.This article is for people who dual-boot Linux with Windows, or boot multiple Linux distributions. If youre using Linux or macOS, and if you cant or dont want to use a distribution package file, the easiest way to install rEFInd is to use the refind-install script.Refind is only a boot manager.We don’t need the GRUB boot loader on EFI-based systems, since an EFI-boot loader stub is built into the Linux kernel itself. GRUB is both a boot loader and a boot manager. A boot manager hands off control to another boot program. Basics Boot loaders and Boot managersA boot loader loads an OS kernel into memory and executes it. If you already have a computer with multiple Linux distributions installed in EFI-mode, then you can skip to the section for installing Refind.
Use Refind For Windows And Mac OS X![]() It is a modern replacement for the old MBR partition table (Master Boot Record) that was used with BIOS systems. GPT Partition TableIn order to use a new hard disk or SSD with UEFI, create a new partition table on the disk in GPT format.Creating GPT partition table with GPartedGPT (GUID Partition Table) is a new partition table format used with EFI systems. EFI on the other hand can provide a complete graphical environment with support for mouse and graphical controls.UEFI Configuration Utility on an Asus motherboardIn order to provide backward compatibility, most EFI systems provide a Legacy Boot mode that can be used to boot your computer. These are stored in partition table and are different from the normal UUID and LABEL that are stored in filesystem. GPT provides a unique UUID (called PARTUUID) and a label (called PARTLABEL) for each partition. GPT partition size is limited to 8 ZB (Zetta-bytes). MBR partition size is limited to 2 TB. GPT supports creation of more than 128 partitions. MBR supports only 4 primary partitions, or 3 primary and 1 extended partition (that can be further subdivided into more partitions). View hard drive for mac on windowsThe ESP is a simple FAT16 or FAT32 partition with partition flags – boot and esp. EFI System Partition (ESP)UEFI requires every bootable disk to have a special partition called EFI System Partion (ESP). You can use these almost everywhere (in /etc/fstab, crypttab, etc) instead of using device names and UUIDs. UUID and LABEL are stored in the file-system and change when the partition is re-formatted.You can refer to devices with their PARTUUID and PARTLABEL to ensure that device references remain valid, even if the partition is re-formatted.In Linux, the device files are referenced as: /dev/disk/by-partuuid/ and /dev/disk/by-partlabel/. These are stored in partition table and do not change when partition is re-formatted. PARTLABEL is empty and needs to be set manually. ![]() Installing UbuntuRun the Ubuntu installer and install Ubuntu to the “xps-ubuntu” partition. This is because the BIOS version of GRUB has been installed (package grub-pc) instead of EFI version (package grub-efi-amd64). You will be able to boot the ISO, run the installer, and install Ubuntu to disk but when you start your computer it will not boot. If you select the wrong entry and boot the USB drive in BIOS mode then your Linux system will be installed in BIOS mode. Write it to a USB drive and restart your computer.Press F11 or F12 (depends on your system) to show available boot devices.Select the option to boot USB drive in UEFI modeThis step is critical. You can install it from a command window: sudo apt updateRefind will display a prompt for installing itself to ESP. Installing ManjaroInstall Manjaro using the “Manual Partitioning” option – Mount sda1 as /boot/efi and sda3 as / Installing PopOSInstall PopOS using the “Custom (Advanced)” option – Mount sda1 as /boot/efi and sda4 as / Installing Refind Boot ManagerOnce all 3 systems are installed, boot into Ubuntu or PopOS and install Refind.Refind is included in official repositories of all major Linux distributions. Since we are going to use Refind, we don’t need any of the files that gets installed on ESP. It doesn’t matter which boot loader gets installed as we will install Refind and remove everything else in final step.Note: While installing multiple distributions you can allow the installer to reformat the ESP partition. PopOS uses Systemd-boot instead of GRUB. Each operating system will install its own version of GRUB-EFI which will overwrite the previously-installed boot loader. Efiexecutables that are installed in ESP. For each entry you can see file path of the EFI-executable or kernel that it will boot.We will hide entries for. If a Linux system has multiple kernels installed, then Refind will add a boot entry for each kernel. Refind will show boot entries for any EFI-executable or kernel that it finds on any partition. Cleaning UpAs you can see in above screenshot, the boot screen is quite crowded. You will be greeted by Refind boot manager screen. Some of the popular ones are shown below.We are going to install a theme named Regular. Refind supports PNG, JPG, BMP, and ICNF icons.Copy icons to root of system partition Final Result Refind ThemesRefind has a large selection of community-made themes that can be installed manually. Under each icon you can see the kernel file name and partition name.To customize the icons for Manjaro and PopOS, simply copy the icon that you want to use, to root of system partition.
