....you can create a LINUX boot disk/drive that might allow you to look at the files on the hard drive, assuming it's not entirely dead... (This does appear to be a dead hard drive, or possibly disconnected cabling between motherboard and hard drive..) But, you can't really make a full recovery disk from a different machine with the same operating system to perform a full reinstall because the drivers and other software on the other machine will be different and will usually cause the second machine to not boot..
Just making sure here... Have you removed all USB devices and any DVD/CD's from their drives before restarting the computer? Simple things such as this can cause "No bootable device" errors occasionally. Have you re-seated the cabling from the motherboard to your hard drive, just as a test?
It would be nice to know more about your computer such as make and model, operating system installed, etc. The more information you give us, the better informed our answer will be.
Hope this helps.

It doesn't boot and it brings me to a screen that says (look below) and for the boot disk can I make one from another computer with the same OS to stick into mine with a usb? Any help is appreciated thank you!
What the screen says:
