Reading a RAW hard drive

Hello, after several attempts, I managed to recover my files from a hard drive that switched to RAW (not readable by Windows) instead of NTFS.
Checking the issue: go to My Computer, select your hard drive, right-click, properties. You can see file system: RAW.
Windows can't read it because the first bytes called the BOOT SECTOR have been modified. This can be fixed with the Testdisk software available for download at the following link:

http://www.cgsecurity.org/testdisk-6.12.win.zip

Look in Downloads, open the downloaded file Testdisk
Launch: testdisc_win.exe to open it.

Select with the arrows create then press enter.
Select your hard drive with the arrows then enter (make sure to identify the letter that designates it or its number of bytes).
Select [intel] intel/PC partition. Enter.
Select [advanced] file system utils. Enter.
Select [boot] boot sector recovery. Enter
Select [rebuild BS] rebuild boot sector. Enter

And if all goes well, you should be able to access your hard drive from My Computer.
