Ms-sys Linux Download
I'm trying to fix the MBR using Ubuntu live CD. I already have the installed but from the threads that I saw, I'm not completely sure in which /dev I should execute the command: sudo ms-sys -mbr7 /dev/??? (is it mbr7 the correct option when using Windows 7?) ubuntu@ubuntu:$ sudo fdisk -l Disk /dev/sda: 320.1 GB, 76 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1. 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x1f205b1f Device Boot Start End Blocks Id System /dev/sda1.

- About This is a Linux program for writing Microsoft compatible boot records. The program does the same as Microsoft 'fdisk /mbr' to a hard disk or 'sys d:' to a floppy or FAT partition except that it does not copy any system files, only the boot record is written.
- Ms-sys run from the terminal in usb-Puppy failed to fix my MBR. It reported that it worked but still cannot boot to hd. This is on a computer on which win xp was previously booting without a problem.
First, your partition table appears to have two active partitions, which may prevent your computer from booting even if you fix the problem of the MBR. Windows's MBR boot is kind of funky because it uses a 'default' MBR to load the MBR of the active partition. Before you change the boot records, try unmarking one of the partitions and booting. If that doesn't work, the package mbr may be worth looking into. It is able to install the 'default' MBR to your disk, which just loads the boot code from the active partition.
As per your question, read/follow these bullet points at your own risk. This stuff has the ability to mess up your partition table. Back it up using dd if=/dev/sda of=table.bin bs=512 count=1 first. I would also recommend backing up all your files. If I understand the docs correctly, doing these commands without -w may prevent them from writing anything without additional user intervention. ms-sys /dev/sda will inspect the hard dist partitions. Please read the documentation.
From what I gather, ms-sys can be quite dangerous and is designed to obliterate your entire MBR along with the partition table in several situations. It would seem you are using the wrong utility for the job.
ms-sys -ntfs /dev/sdaX where sdaX is your partition with Windows 7 on it. This might do what you are expecting, but probably not. I think you have the wrong utility for the job here. This does not 'fix' MBR's, it destroys and creates them. You may get lucky and have the new partition table line up with the new one, but I wouldn't count on it. Try booting a grub CD and typing chainloader (hd0,)+1 at the prompt and seeing if it boots. This will help diagnose where your problem is.
If else fails, use your windows installation dist to fix the MBR. Here are the two solutions that have have worked for me. Boot Linux and make sure you’ve a working Internet connection and type the following on the terminal.

Solution sudo apt-get install syslinux If the package got installed, use the following command to write the MBR: sudo dd if=/usr/lib/syslinux/mbr.bin of=/dev/sda 2. Solution sudo apt-get install mbr If the package got installed use following to write the MBR.

Sudo install-mbr -i n -p D -t 0 /dev/sda Common for both Replace sda if you want to install the MBR to a different drive. Do not put sda1, sda2, or sda3.
Just put it as sda for the hard disk. Finally reboot and your Windows should boot.
