Recovering GRUB/Arch Linux after installing Windows 7

Question

Like title, how can i detect my webpage have refreshed?

Solution

GRUB has an internal way to do it, which I've found may work when grub-install does not. It requires an existing /boot/grub, which you should have lying around.

On a LiveCD, open up the GRUB CLI (su -c grub) and run:

find /boot/grub/stage1
root (hdX,Y)
setup (hdX)

Use localstorage to set a specific value and have a check if that has not been changed.

@Chiggins It should. GRUB knows how exactly to locate its own stuff within most any partition type, and shouldn't require any extra mounting.

Alright cool, thanks for that. I'll give it a shot when I get home.

You can try this: $('body').unload(function() { //do something });
