How to "rename your USB media"?

When I boot into the Arch live ISO, sometimes (but not always, with no configuration changes on my part) I get the following error:

ERROR: '/dev/disk/by-label/ARCH_201807' device did not show up after 30 seconds...

The Arch wiki says at https://wiki.archlinux.org/index.php/US … leshooting:

If you get the "device did not show up after 30 seconds" error due to the /dev/disk/by-label/ARCH_XXXXYY not mounting, try renaming your USB media to ARCH_XXXXYY (e.g. ARCH_201501).

However, it doesn't explain how to do this (or, for that matter, why it might be expected to help). Firstly, can I do it from the interactive prompt on Archiso? If not, how can I do it from macOS (the system I used to copy the ISO to my flash drive)?

I couldn't find any relevant wiki page or online resource that explains what is meant by this troubleshooting advice.

Re: How to "rename your USB media"?

Some usb writing software messes up the label making it harder for bios/uefi firmware on boot to detect the iso.

Afaik this can only be changed when the drive is not mounted.
What program / command did you use to create the usb stick ?


Booting with apg Openrc, NOT systemd.
Automounting : not needed, i prefer pmount
Aur helpers : makepkg + my own local repo === rarely need them

I use macOS, so there was only one option according to the wiki: https://wiki.archlinux.org/index.php/US … a#In_macOS

You can use e2label to rename ext2/3/4 partitions, exfatlabel  for ExFAT partitions, etc. See https://wiki.archlinux.org/index.php/pe … g#by-label for a list.

Re: How to "rename your USB media"?

I'm pretty sure the quoted advice from the wiki is red herring.  If you only get that error some of the time, then the filesystem must have the correct label or else you would get that error every time.

Is there any pattern of when it works and doesnt: are you using different usb ports?  Or is it on different hardware?

Flash drive quality can vary a lot. What does lsusb call it when it does work?

Nope, I literally just booted from the USB and it failed, then did a hard reboot without otherwise touching the machine and it worked.

There are two partitions listed from the flash drive on the UEFI boot menu for some reason (is that normal?) but I always pick the first one.
