Hi,

looks like you booted in single-user mode (by pressing cmd-s at startup).
If so, type :
exit
Press enter and the Mac should boot (but in single user mode).

For booting from an external drive , keeping pressed option at startup is all you need to get to the bootable drives.
Select a drive and press enter.
