How can I install & run testdisk with USB?
When I boot from HDD, i can download & install testdisk from ubuntu software center; but when I boot from USB (for the purpose of recovering my NTFS drives that were accidentally dissolved into one EXT4 by 14.04) I can not even find testdisk inside ubuntu software center. So can not run testdisk from terminal when I boot from USB.
Is booting from USB a MUST for trying to recover NTFS drives?
Please help I am badly confused :( :`(
