(Link applies to Windows 10 also.)
The following link may be more applicable.

Requires EaseUs so that in itself may be another problem for you unless you have access to another system where EaseUs can be installed.
However, there are other factors and options. The following link is more comprehensive:

Take your time, look for additional links, and work out the viable options with respect to your system.
If there is a hardware failure (or pending hardware failure) then that may make recovery all the more difficult.
Key is to protect yourself from data loss. Backup data if at all possible, first thing once the system is booted.
