I was trying to make it normal from grub rescue error. But, msdos7 is returning that filesystem is ext2. When I write insmod normal I get "invalid file name 'hd0,msdos7/i386-pc/normal.mod"

How can I fix it? I have bootable USB . that's arch Linux. Even, I tried by bootable USB also. When I reboot my laptop that(grub Loader) don't show anymore(like it had erased automatically when rebooting). I was following the answer https://askubuntu.com/a/462995

When I tried to search search.file ... I got an error unknown command 'search.file'.

This is how I installed grubloader but, I am getting the grub error although. /dev/sda7 is arch Linux. And, /dev/sda1 is windows.

I had Kali earlier. I had deleted partition/volume of kali,swap and grub from windows manager.

I noticed that type /dev/sda7 is ext2. But, I remember that I formatted it to ext4.

Now, I have Linux Mint bootable USB.

root@mint:~# mount /dev/sda5 /mnt
mount: /mnt: /dev/sda5 already mounted on /mnt.
root@mint:~# grub-install /dev/sda5
Installing for i386-pc platform.
grub-install: error: failed to get canonical path of `/cow'.

I was following the video. I notice that he set flags to bios_grub. But, I don't have bios_grub. What to do now?


By following the video I had solved this issue.

sudo mount /dev/sda7 /mnt
sudo mount --bind /dev /mnt/dev
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys
sudo chroot /mnt
grub-install /dev/sda
sudo umount /mnt/dev
sudo umount /mnt/proc
sudo umount /mnt/sys
sudo umount /mnt
reboot now

But, I am facing another issue here
