How do you permanently fix grub rescue: unkown filesystem

I have a dual-boot of Ubuntu and Windows 10(dev/sda1) And it shows me this:

grub rescue: Unknown Filesystem
grub rescue>

And this is what I have to type to fix it:

grub rescue> set boot=(hd0,msdos6)
grub rescue> set prefix=(hd0,msdos6)/boot/grub
grub rescue> insmod normal
grub rescue> normal

But I have to type this every time I restart my PC. Is there a way to make this fix permanent and update grub? Thanks

After those commands you type on grub rescue, you should update grub once you boot into Ubuntu, by running:

$ sudo update-grub

and then:

$ sudo grub-install /dev/sda

After this is done, reboot your system and check if the problem remains.
