This question is an exact duplicate of:
- I had windows Os on a 160GB disk . so i created a bootable usb for kali linux to install side by side with windows. so during installation i selected partition method .( guided partitioning - use entire disk). then i selected All files in one partition (recommended for new users). so the installation process began . then i shutdown the pc because i thought i made a mistake.
2. so then i loaded the installation again this time choosing manual partioning method and the whole disk was shown as free space. i created a logical partition of 50 Gb plus swap space, and the rest was free space. i proceeded with installing kali linux on the 50GB partition. thats when i decided to use the testdisk utility but i realy dont know what happened ?
testdisk under advanced with disk partition marked x Extended shows
Boot sector Status: Bad Backup boot sector Status: Bad Sectors are not identical.
A valid NTFS Boot sector must be present in order to access any data; even if the partition is not bootable.
