I have installed Kali 2017 everything went fine installation finished. After restart GRUB loader don't shows any option to load into Windows only option to load into Kali. I have read somewhere to manually edit grub file like below but after this selecting windows option in grub shows error disk 'hd0,msdos4' not found.

menuentry "Windows 8" {
insmod part_msdos
insmod ntfs
set root='(hd0,msdos4)'
chainloader +1

enter image description here

Last three partitions are created after installing kali. Also in boot menu in efi only kali grub is showing as boot device. I have tried sudo update-grub too but no success.

update GRUB

enter image description here

There is no windows boot manager in the boot menu there is only option for Kali, have i did something wrong.

You need os-prober to detect your windows.

apt-get install os-prober
  • actually i think i have removed the partition which contains boot information of windows. Any way i can repair that ? Aug 10, 2017 at 19:13
  • AFAIK, there is no such thing as boot information of windows. If you are able to enter Kali from grub, your boot information is intact. Did you try my answer? Aug 10, 2017 at 19:16
  • I tried but does't help. Aug 11, 2017 at 10:07
