So my linux experience started off by abandoning windows for a week and trying ubuntu 17.04.
then i wanted to switch back to windows so i downloaded an iso file to put it on my flash drive using etcher and when i tried to boot the flash drive it always booted ubuntu instead.
so idiot me had the idea of deleting the ubuntu partition so i did that and then rebooted and im stuck in grub rescue it says:
error: file'/boot/grub/i386-pc/normal.mod' not found.
entering rescue mode...
grub rescue>
