I find this highly embarrassing, but I can't find the answer, so I must ask for your help.
I have a dual boot system and I have killed the mbr, so normally I would boot into rescue mode and use the grub-install command (I have done this several times before).
But my computer is a netbook and has no optical drive. I have installed Fedora when I first got it, using liveusb-creator and a live image of Fedora 10. However, when I boot from this live usb, I have no rescue mode available. I tried adding "linux rescue" to the parameters, but that didn't do anything either.
Can anyone help me?
