Hi all,
I have accidentally installed grub2 in my mbr and now i cant use win8.

Can I use my ubuntu 12.10 live to uninstall completely grub from my system? You know that i ve done the following actions:

First I ve installed boot-repair and from advanced i ve chosen top fix mbr. Once it removed correctly grub2.
Not this time. At reboot appairs the grub2 minimal command line.


Secondly I have tried the win8 command line bootrec.exe /fixmbr, but at reboot appairs the grub2 minimal command line. That has happened three times.

Any suggestion?
