Restoring the MBR in Arch.

Hi: any utility to restore the master boot record (boot sector in the linux jaergon)? Lilo could do it (lilo -M /dev/sdX mbr) but the target is an eMMC device and lilo can't write it. Perhaps grub can? "Restore" means to write, in logical sector 0 of the disk, the code expected to be there to load the MS-DOS OS. Nothing to do with the partition table. The code begins with a 0xEB90 jump to the code proper.

Re: Restoring the MBR in Arch.

The MBR holds the information on how the logical partitions, containing file systems, are organized on that medium. The MBR also contains executable code to function as a loader for the installed operating system—usually by passing control over to the loader's second stage, or in conjunction with each partition's volume boot record (VBR). This MBR code is usually referred to as a boot loader.[1]

The syslinux MBR will start syslinux, if that's not what you need/want , check http://bootdisk.com/ .
