Fix NTLDR or any MBR problems with Linux!
If you have run into a problem with booting its usually caused by the MBR (Master Boot Record) being corrupted it is the first 446 bytes of a hard disk, it usually stores boot information and or a boot loader. to wipe the MBR without destroying the partition table or any of your files boot into Linux using a live cd.
Open a a terminal as root and enter the following command.
dd if=/dev/zero of=/dev/sda count=1 bs=446
sda is usually the first master disk, this can change but its usually sda.
