Hi there and welcome
Can you tell me which version of windows you had? and the model of the computer please
That is no problem
Can you power it off.
Then hold the ALT key on the keyboard and with it held, power on the computer and keep tapping F10 until you get to the recovery manager
tell me if you can get to this which means they put a recovery partition on the computer.
I cannot here as we are technical support, but if my instructions did not work, then call 0371(###) ###-####when your at the computer as you need the serial number from it and one can then be sent.
Also, the caddy your referring to you can purchase from my link below
If you would like any additional information or assistance, please do not hesitate to let me know.
