#Clonezilla with grub on usb iso
In the following examples, the ISO file is located in the /iso folder of the partition /dev/sda5 alias (hd0,5) in grub. Please refer to the ISOBoot page if you have questions regarding the correct paths, formatting and ISO file location designations. The main files referenced in the menuentry, vmlinuz and initrd.lz, are located in the ISO's casper folder.
If an example of a desired ISO is not listed, the user may be able to determine the proper menuentry commands by comparing the file structure of the ISO with the menuentry commands of ISOs laid out in a similar fashion. General information on creating a GRUB 2 menuentry is provided on the Grub2/ISOBoot page. This page has been created to allow Ubuntu contributors to provide known, working menuentries for the ISOs of popular Linux and utility discs. Lubuntu Focal released as 20.04 LTS and booting with grub 2.04.Lubuntu 18.04.1 (64-bit) persistent live.Next, run grub-mkconfig to create a grub.cfg that can boot the available OSes: $ grub-mkconfig -o //boot/grub/grub.cfgĪlongside grub.cfg, add custom.cfg with GrUB stanzas for future rescue and configuration purposes, the key section being the one that changes menu configuration to that of the live USB. $ grub-install -target=x86_64-efi -efi-directory=// -boot-directory=//boot /dev/ This command creates EFI/debian/grub圆4.efi and adds the corresponding boot/grub (drivers) tree to the card. Having booted linux via legacy boot options, the message “grub-install: warning: EFI variables are not supported on this system.” appears here, but is harmless. Start by installing the EFI version of GrUB to the card.
This is a necessary addition as grub-pc doesn’t provide these. In order to ensure binary components for GrUB on 64-bit UEFI systems is available for installation, debian’s grub-efi-amd64-bin package should be added (or upgraded) first. One of my live debian system thumbdrives is being used to set up the card, having been booted on the UEFI system with CSM (legacy boot) support temporarily enabled.
#Clonezilla with grub on usb free
Formatted for transferring data recently, its DOS partition table has one primary partition with 1MB reserved space and an MS-DOS filesystem occupying its free space (of type FAT32, but UEFI BIOS implementations should also be able to read FAT16 or FAT12 – YMMV mine did, but support for all FAT variants, for checking content of all primary/any extended partitions/unpartitioned “superfloppy” disks, or booting from all device types and even all ports may be buggy, intentionally omitted, or phased out over time). This article covers how.įor this task, I have a 4GiB microSD card in a USB card reader. With GPT partitioning only a hard requirement for disks of 2TB or more, the option of leaving legacy media devices with the native DOS partition table and simply adding relevant files is available. Under a decision dating back to the Intel Boot Initiative (latterly EFI) design for Itanium systems, it was decided that booting a system should no longer have to depend on a boot sector (plus associated reserved space) and instead require the presence of a filesystem – in particular the widely-supported FAT (MS-DOS) filesystem. Having recently spent some time with a UEFI system, I learnt of the possibility of making a device bootable without also using a GPT partition table.
