After accidently formating by windows(i use kali alongside win as dual boot)
i entered into grub rescue, and did the usual stuff to recover grub
set prefix=(hd0,gpt2)/boot/grub
set root=(hd0,gpt2)
ls /
insmod normal
normal
Boot into kali Linux.
Open a Terminal window.
Type the following command and press Enter:
update-grub
Type the following command and press Enter:
sudo grub-install /dev/sda
.
after that i'v found the swap partition related problem.
i'v used gparted to re-create my pre-problem swap partition,,,which is now /dev/sda8 and set a new uid for it then i swapon it,,,, and rebooted. but problem remains intact.
.
here are some useful information...and Attachments:
