No bootable device detected
If you strike F1, the system retries as said in the comment. That does'nt solve anything. Rather strike F2 which allows to enter the setup menus of your computer.
In this area you should understand what you are doing. Any update of setupdata may prevent further restart. At least take note of values and changes. You exit setup via a question "update Y/N". Then the computer restarts.
Anyway, in the setup menu you may inspect the devices and see if you the system identifies the disk. If not it may come from a bad connection of hard disk (sata pins, ...) or from low level disk information (format information).
With setup menu you may get in the boot order menu, that allows for the selection of an alternate boot media. You may boot on an installation media, ( install DVD generally, like originall windows install DVD) in order to understand and repair the situation, or from a rescue system like UBCD. You may also try Ubuntu from the CD without installing, just to verify if you may see the disk in the configuration.
