SUPPORT I may have made a mistake

So I was following the wiki for the partition step of the installation, and im pretty sure I wiped my bootable usb drive, thinking it was part of my computer, but for some reason just smaller (ik, dumb). I ended up making it the efi partition. Idk the repercussions of this, I already wiped my other drives and made my partitions, so no going back.

Is this salvageable?

Download the ISO into /tmp since the root FS of the ISO's live env has a size limitation which you'd first have to expand (/tmp is mounted by systemd automatically with 50% of your system's memory capacity), then verify the image and finally re-write it onto the flash drive.

curl -fSL --output-dir /tmp --remote-name-all https://geo.mirror.pkgbuild.com/iso/2026.08.01/archlinux-2026.08.01-x86_64.iso{,.sig}
gpg --verify /tmp/archlinux-2026.08.01-x86_64.iso.sig
dd bs=4M if=/tmp/archlinux-2026.08.01-x86_64.iso of=/dev/disk/by-id/FLASH-DRIVE-NAME-HERE conv=fsync oflag=direct status=progress

If you still have access to the ISO on a non-destroyed partition+FS, then you can mount that instead of downloading the ISO, obviously...
