I can’t seem to write the ISO to my USB. When I try to boot off the USB, it always gives me a “Can’t authenticate” error. Can someone help?
Are you using the recommended procedure from Burn an ISO File - Manjaro ? Disable Fast Boot, Secure Boot from your BIOS too and make sure you use AHCI for SATA controller.
I recommend using Etcher or Ventoy.
Open File Explorer and Right Click on the USB icon which will open up a Menu. About 3/4 down you will see FORMAT. Select this and then select NTFS. You should be able to copy the ISO to your USB. Try Rufus if you facing issues. It may help you easily.
