I have a system that I have installed 3 partitions.

 

1) Windows 7

2) Recovery/Grub4Dos/etc (hidden from user)

3) Data drive

 

I have everything working and it is booting with Grub4dos with the menu.lst working as I planned.

 

However, if I make a full clone of them system using ImageForLinux, including the MBR, and restore it on another machine (also restoring the MBR), I get the following error message, haulting the boot process.

Missing MBR-helper.

I haven't tried it yet, but I imagine if I use grubinst (windows) and reinstall Grub4dos, it will work fine, but I really need the systems to be bootable directly after a full clone (for production purposes).

 

In the meantime, I have booted to a Linux LiveCD and ran bootinfoscript to help diagnose why this is happening.

 

Any help would be greatly appreciated.

Ignore my 4gb thumbdrive that was included into the report. I had to use it to boot the Windows 7 partition on the larger drive (because MBR is broken).

grub4dos installs to the MBR and about 60 sectors after the MBR. Preserving just the MBr is not enough. Try backing up the first 63 sectors instead.
