I tried 3 times to boot majaro-deepin and it failed.
I used two different sticks and two different usb makers.
It does not catch the boot and so I force it with the boot key and then it
goes in to a prompt and that is it.
I hope that you can boot with uefi instead of legacy mode because I have windows already installed.
I did the checksum and it was the same, but I did the gpg and that failed. (Probably did the command wrong)..
Is the deepin install iso unstable?
I had to google the location because it is not standard on the majaro download page.
