Sony Vaio Stuck on welcoming screen, with no way to help?

Heres the story....i would try to go in safe mode and such but my laptops screen is cracked meaning im using a monitor and it doesnt show until it gets to the screen where you choose your user.

I need this fixed badly if theres any way anyone can help me please im desperate.

I have extremely important files on that PC. My job requires those files back. and now i feel im screwed and im scared it all lost forever.

Please,,,any advice? or anything to do? If needed ill post a video of what i mean but its only a stock sony vaio nothing fancy. Please guys im not tech smart and i apollogize for sounding stupid but understand..

Thank you for taking the time to read this!

It is normal that a laptop won't use an external monitor in pre-OS environment. You won't lose files because of this. However, you should be backing up your user/data files when everything is running normal, because it may not be so tomorrow!

See Notebook screen busted, display refuses to work pre-OS : techsupport

Edit: Some laptops do have such a feature but it is normally a premium one.

Thank you for the reply and link! I guess i should just get the screen fixed but even so how will i be able to fix the problem im having without having to reset the whole system back to factory settings? because most of the time im always told thats the only way and theese files are extremely crucial for me to get back :/

Use the Force! :)

Use intuition, start the laptop, and tap F8 every second or so, do this for, say, 30-40 seconds (hopefully opening Advanced Boot Options), then press down arrow once (to select Safe Mode) and hit ENTER.

See if this will help.

For Safe Mode with Networking press down arrow twice and hit ENTER.

You an also try booting with Linux Mint MATE DVD (DVD should be 1st boot option by default), don't create bootable USB as it would require to change boot order which you can't see. Then copy paste your files.
