January 18, 20251 yr Hello, there are threads about moving UNRAID to an USB stick, etc. But I found no hint, how to "burn" any generic ISO image to an USB stick, like I could do with "usbimager". Also, it seems, I can't find any precompiled "usbimager" for Slackware. Since I want the filesystem on the USB stick to be writable, I can not use "dd", as outlined here under "dd". As always, any ideas?
January 18, 20251 yr Community Expert There is no 'iso' for Unraid. The flash drive is just a standard FAT32 format drive and no special tool is needed. Unraid does provide the USB Creator tool that tries to automate formatting the flash drive and copying files to it , but there is nothing stopping you from doing this manually. Maybe you missed the fact that Unraid loads itself into RAM from the flash drive when booting and runs from there, with the USB stick just being used during normal running for licence verification and for storing User settings. There is no concept of an install onto different media.

I am not talking about the UNRAID installation. My Desktop PC hard drive has bad blocks and thus I can not boot it. I want to write the ISO image of SystemRescueCD onto an USB stick for initiating a recovery process. The only running system I have is my UNRAID system. Therefore: I download the SystemRescueCD ISO to my UNRAID server's download folder. On the UNRAID host I "burn" the SystemRescueCD to an USB stick. I boot the desktop machine from the USB stick. Eventually modify configurations on the SystemRescueCD and save them on the USB stick (this is why a simple 'dd' is not enough, since it would only copy the ISO image to the USB, but ISO is read-only. Programs like 'usbimager' seem to recreate the ISO as a bootable Linux filesystem on the USB stick) Edited January 18, 20251 yr by amix
January 18, 20251 yr Community Expert Not sure there is any way to do this directly on Unraid. You could possibly do it from a docker container and/or VM but never tried this. An easy alternative is if you have any system (possibly a friend's) that can run Windows and then use something like rufus to do this.
