I Rebooted my Lenovo Laptop with OneKey Recovery. Can any information or files be recovered?

You will be able to recover some files if they have not been written over

use the 'deep scan'

you will need another drive to save the files to.

You can use asoftech data recovery software, download from

Used it before. Easy to use and worked well for me.

Files of partition except system partition can be recovered.
