Ubuntu on USB drive- Error 15

[covfefe2502]

So I just installed Ubuntu on a USB using the Universal USB Installer(NTFS Format). I put the drive into my laptop, booted it from the USB, and it showed me two options:

Boot ubuntu-16.04.2-desktop-amd64
Boot ubuntu-16.04.2-desktop-amd64 acpi=off


When I choose either of them and boot, this shows up:

Booting 'Boot ubuntu-16.04.2-desktop-amd64'

find --set-root %ISO%

Error 15:(http://grub4dos.chenall.net/e/15)
File not found

Press any key to continue...

When I press a key, it just goes back to the previous screen. Any help?

Thread moved to the "Installation & Upgrades" forum.

What's with the link next to Error 15? It doesn't seem to work. But the forum has its own image attachment facility. Try that.

That's what was displayed. I added a picture of the screen, if that helps.
