I have installed a TurnKey system on a USB key with no problems, however the system cannot boot after installation.

I used guided installation, no LVM.

I have set the bios to boot from the USB key, but all I get is an _ (underscore) on the top left corner of the screen.

Is there something special to do when installing to a USB key?

I've never tried installing it to a USB, but I would expect it to work, at least on the machine that you used to install it to USB.

As TurnKey is almost exclusively used for hosting, it's usually run as a VM (or other virtualised environment, such as LXC. Unfortunately, the knock-on effect of that (and we're a small team) the TurnKey hardware support is sub-optimal.

Having said that, if it wasn't going to work, I would have expected an error (or errors), rather than just sit there with a blinking cursor. The blinking cursor suggests it's not even getting passed the bootloader or perhaps the super early stage of OS boot?

How long have you waited for it? It might just be that it's really slow? USB 2 is pretty damn slow. Note that even if you are using a USB 3 compatible stick in a USB 3 port, the initial minimalist kernel used at boot time, likely doesn't have USB 3 support, so it would be running as a USB 2 device. Another possibility is UEFI (and/or secure boot). Unfortunately TurnKey doesn't support UEFI boot, so perhaps try disabling that (often there is an option to enable legacy BIOS) and it definitely doesn't support secure boot (so you'd definitely need to disable that!).

Out of interest, what is it that you are trying to achieve installing it to a USB?
