I got stuck in GRUB while installing Linux Mint Xcde and I can’t get out

So, I was just installing Linux Mint on my laptop and it just bricked itself. Im stuck in GRUB and linux /vmlinuz root=/dev/sda3 doesn’t load the kernel. The engine just replies with ‘file ‘/vmlinuz’ not found’. I think hopefully I have the wrong root but if I do have the right root and the file isn’t there im fucked and this laptop is bricked. ‘boot’ doesn’t work because as mentioned earlier, I don’t have the kernel loaded.
