I have installed kali linux from a live usb. I use dual boot option along with windows 7. After installation when grub is loading, it requires my usb along with it for successful loading. Else a missing device error is prompted and grub rescue option is shown. Can anyone help me with this problem. Thanks in advance
It seems like you have installed the grub to the USB drive. To fix this ,
From your booted linux system, open a terminal, then use the following commands :
sudo grub-install /dev/sdX
Replacing sdX with the actual drive, which will probably be sda, but use disk utility to double check if you are unsure.
