Hi @gilphilbert and welcome to the Manjaro community.
bad super block, wrong fs type, bad option...
typically indicates an issue with the filesystem - at face value, it seems that you’re consistently writing bad USB Installers.
You could try writing the ISO to a DVD instead.
Or, consider creating a Ventoy USB;
I would normally give more information here by way of explanation, however, I’m running a little short on time:
1. Install Ventoy:
sudo pacman -S ventoy
2. Obtain a new empty USB drive - minimum 8GB (32GB might be preferable for reasons that will become obvious).
3. Insert the USB drive, and find it’s location in the device tree (/dev/sdXY).
4. This is the command I would use for creating the Ventoy USB:
sudo sh ventoy -i -r 100 -S -g -L VOLUME /dev/sdX
- Enable
-s
or disable-S
Secure Boot. - Substitute
VOLUME
for a volume label name to use. - Substitute
/dev/sdX
for the location of your USB device. - Preserve some space on the target device (example allows 100mb).
5. Download your (full) ISO; verify that the checksum matches; Using the torrent option (if available for your ISO) by it’s very nature might be a better choice if your usual download method is failing.
6. Here’s the part that’s makes this process unique; Copy/Drag the ISO to the Ventoy USB; Now, boot your machine using the Ventoy USB, and select the ISO from the menu that is presented.
That’s it. Good luck.
A little housekeeping…
