I have an external hard drive with elementary os on it, and when I took it out my preinstalled windows 8 laptop, it came up with the "error: no such device:'hex number' grub rescue>". I can't boot from the external hdd, no live usbs, can't get to bios, and when I type in ls, it comes back with only "(hd0)".
I have found articles that tell how to fix either just the ls problem, or just the boot error problem, but none of them will let me fix all of them. Ask ubuntu is telling me that this is off topic on their site. At this point, I don't think that I really need the files on the computer, but just an operating system on it. Either the elementary, or some way to get back to windows 8. If anyone can help me just install any kind of os on it, I would be overjoyed.
The computer is an Asus X502C. When I put in "find /boot/vmlinuz", it just says that "find" is an unknown command.
