I accidentally erased all data and Windows laptop what can I do
If you formatted your drive on accident, there is still a chance. Get another computer, and mount your old hard drive on it. Then, use this software to try and recover your list data: https://www.powerdatarecovery.com/lost-p… It may or may not be successful at recovering your neccacery but it should be enough to at least get some of your data. If it can’t recover the OS, use a bootable USB stick to re-install Windows. I can provide a guide when you tell me your version of Windows.
