Can you help me fix my laptop?

Help, please! My laptop (Toshiba equium) isn’t working and I have no idea why. It has so much of my work on it and im desparate to get it up and running again, if any one can help I would be so so grateful.

It comes up with this on start up –
_________________________________________________________
Windows Error Recovery
Windows failed to start. A recent hardware of software change might be the cause.

If windows files have been damaged or configured incorrectly, Startup repair can help
diagnose and fix the problem. If power was interrupted during startup, choose start
windows normally.
(use the arrow keys to highlight your choice.)

Launch startup repair (recommended)
Start windows normally
_________________________________________________________

If I choose ‘Launch startup repair’ then it comes up
‘windows is loading files…’
then a loading screen then a window comes up saying –
‘startup repair is checking your system for problems…’
after just a couple of seconds this disappears and then a window that says
‘windows cannot repair this computer automatically’ comes up with theses options –
‘view diagnostic repair details’
‘view advanced options for system recovery and support’
‘finish’
And ‘cancel’
__________________________________________________________

If I choose ‘Start windows normally’ then a load screen appears for a few seconds before it simple restarts and goes back to the ‘Windows error recovery’ screen.

Please help.
The diagnositic repair retails are miles long, to long to type out.

I do not want to lose my information, I have important work on my laptop – please help.
