Im new to this technology and inadvertently clicked repair computer in the safe mode box. That action cleared my Toshiba C650D-O2Q computer of all data

Sounds like you have done a factory restore on the device, in which case YOU set what every password you want.

The words Bootmgr is missing shows up and it says to press ctrl+alt+del to restart. Now what do I do people. I can make it to a Boot Menu page. After that I'm lost. Help please?

Press Ctrl+Alt+Del as advised.
