Fixing Grub Error - No Such Partition Unknown File System 

As my system was dual boot and This grub system error came but i was not able to fix this grub error this way i fixed this problem and i can dual boot using Bios key first u need to go to bios setting of ur device by pressing BIOS key according to ur device while restarting (or search yt tutorials to go to ur device bios ) 1st Step: some bios key for specific devices are given below :(if ur device list is not there then u can do google for ur Bios Key) 1. Lenovo F12 (Nano Button, Fn + F11) 2. HP Esc F10 3. Dell F12 4. Asus Esc F2 or Delete 5. Sony Assist Button, Esc, F11 F1, F2, F3 (for some models) 6. Toshiba F12 F2 (or Esc for some models) 7. Fujitsu F12 2nd step: Once u are into your bios setting ! u can choose in which system u want to go in case of mine there were two OS( i.e kali linux and Windows) i choose Windows then it started normally as usual U can choose other OS like Kali and go to that system U can always change the os by going to bios setting by restarting and pressing bios key as in first step Thank you
