Hopefully a LQ'er will post the precise arch way to do the sha256 checksum *ON the USB*
I web-searched (but I don't know if arch has those cmds): SHA256 verify usb
Which
city did you dl it from? (SHA256 checksum 50a1c... there) Info on your PC/BIOS?
(are you sure it was booting from the USB ok? Probably. Any BIOS setting 'issues'? Prob not)
Oh, *WELCOME* to LQ! The right 'guru' will soon arrive here
p.s. in the meantime, you might cat that rdsosreport.txt & web-search ?key? msgs
Hope you enjoy (as I do!) these little 'puzzles'
