Hello everyone,
I’m having trouble getting rEFInd to boot Arch Linux directly from an ISO. I installed rEFInd on a USB drive (using refind-flashdrive), set up refind.conf file and wrote the ISO file to separate partition, but I’m encountering issues when trying to boot into it.
Here’s the output of the lsblk command:
NAME FSTYPE FSVER LABEL UUID FSAVAIL FSUSE% MOUNTPOINTS
sdb
├─sdb1 vfat FAT12 REFIND B28E-9C53
└─sdb2 iso9660 Joliet Extension ARCH_202508 2025-08-01-13-39-26-00
Menuentry from refind.conf
menuentry "Arch Linux" {
icon /EFI/refind/icons/os_arch.png
volume "ARCH_202508"
loader /arch/boot/x86_64/vmlinuz-linux
initrd /arch/boot/x86_64/initramfs-linux.img
options "root=UUID=2025-08-01-13-39-26-00 rw"
}
When I select the Arch Linux entry in rEFInd, I receive the following output:
:: running early hook [udev]
Starting systemd-udevd version 257.7-2-arch
:: running early hook [archiso_pxe_nbd]

You can try to fix the problem manually, log out when you are finished
sh: can't access tty: job control turned off
[rootfs ~]#
The only way I found that worked was to use the loader /EFI/BOOT/BOOTx64.EFI in configuration, which works but is not what I want.
I would appreciate any guidance on how to resolve this issue.


root=isn’t correct for booting a live image like this. You need to use some specific parameters to guide the initramfs to where it can find the/boot/x86_64/airootfs.sfsfile, and in general, something like that will be the case for most distros but there are lots of unique mechanisms. Looking at thegrub.cfg,/loader/entriesor similar files will usually get you some things you can put into your favorite search engine to hopefully find some documentation. For Arch it’s part of mkinitcpio-archiso: https://gitlab.archlinux.org/archlinux/mkinitcpio/mkinitcpio-archiso/-/blob/master/docs/README.bootparams?ref_type=headsI don’t have a setup to test it but if If I’m not mistaken something like this should work:
I did not know. I found these options on ArchWiki: https://wiki.archlinux.org/title/REFInd#For_manual_boot_stanzas
I tried your
optionsand they worked. Thank you for your help!
