Help! I can't boot from a USB?

[MisterVortex]

When ever I try to boot from a USB, I get a windows error, it will always boot into my regular SSD. I tried changing the boot order, no luck there! I'm lost please help!

It's also not the USB, I tried it on 3 other computers and it worked fine...

Sometimes there is a message on the top left of the screen that says: "Press any key to continue". If you miss that. it will default to a normal boot from your default device.

Some MB's can restrict booting from USB. Check the BIOS, or post make/model.
It'd be nice if you could mention what this mysterious windows error is too.

What is the USB for? WIn7 install?

Try triggering it using the one-time BIOS Boot Menu key given on first screen, under USB, Removable or HD"s.

What does it boot into?

In other words, how did you create the bootable USB and to what purpose?

More or less the same question greg asked but eliciting more details.
