This is not a programming question but iam out of solutions ,
Originally i’am on windows ,
And i have a USB i burned kali linux on it using rufus with the DD method and setup the system and all is well, till i decided i was not ready for linux and used WoeUSB to burn an iso windows 10 and went back to my default OS , MY PROBLEM IS AFTER I WENT BACK I FORMATED MY USB BUT A CHUNK OF IT WAS NOT APPEARING and IT IS WELL HIDDEN , AND I THINK IT STORES THE LINUX BOOT SETUP , and it is organized using a way that only linux OS’s can recognize and see
