From the command prompt window, type bcdedit and check the bottom of the readout for a safeboot entry.
If it is there, type bcdedit /deletevalue {current} safeboot and it should remove the entry and get you out of safe mode.
This command is normally run from an Administrative command prompt, but I think the one you are seeing is an administrative version.
If your bcdedit command shows more than one boot loader, as in a dual boot situation or possibly an offline boot, you may need to add the id of the boot loader. It uses {current} unless something else is given.
