Solved: Mount Can't Find PARTUUID

Trying to do a new install on a deleted or erased disk.
Booting from archlinux-2024.11.01-x86_64.iso copied to USB flash disk.
Getting "Failed to mount on real root".
The PARTUUID that arch is trying to mount doesn't seem to match any device returned by blkid or listed in /dev/disk/by-partuuid.

Re: Solved: Mount Can't Find PARTUUID

Booting from archlinux-2024.11.01-x86_64.iso copied to USB flash disk.

How?

Partition the USB flash drive and format it to FAT32.
Right click on archlinux-version-x86_64.iso and select Mount.
Navigate to the newly created DVD drive and copy all files and folders to the USB flash drive.
When done copying, right click on the DVD drive and select Eject.
Eject the USB flash drive.

I guess that's not relevant here as the boot error is from the new system - not from arch install - as that output would look quite different

@OP
what boot do you use and how have you set it up? the uuid doesn't match anything - from my vm tests I would guess you used refind and its install script and not configured it properly so it tries to boot the install media's uuid

I don't know what refind is, but i didn't use it that i'm aware of. I got the above error simply booting the live USB, without executing any commands.

I resolved that error. I did two thing differently. Not sure which one helped:
- I used archlinux-x86_64.iso instead of archlinux-2024.11.01-x86_64.iso
- I used rufus instead of manual copy (maybe wiki should be updated?)

But now onto new errors:
- tried pacman -Syu immediately upon boot, to update the flash drive. I got "no space left on device".
- tried archinstall, and got "no space left on device"

Next i tried manual install.

New error trying manual install:
mount: /mnt: unknown filesystem type 'ext4'

Do not update the live disk. That's totally pointless and causes problems.

Ok.
archinstall fails with "no space left"
mount fails with "unknown type ext4" (pics above)

Re: Solved: Mount Can't Find PARTUUID

Both would be the result of trying to do an update on the live disk. Reboot.

Success!
Which one of these do you think solved my boot issue (first post above):
- archlinux-x86_64.iso instead of archlinux-2024.11.01-x86_64.iso
- rufus instead of manual copy

thx

Re: Solved: Mount Can't Find PARTUUID

as the link without the date is just a symlink to the one with the date they are both the same file
as for using rufus: could be as it writes the entire structure of the image including the partition table - but I doubt that the image has a hardcoded partuuid in its config but rather something gerenic - as for uefi it is sufficient to just copy the files instead of having to "burn" a proper bootsector
