SLES 10.X Does Not Start Successfully After a BMR

Valid on SUSE Linux Enterprise Server (SLES) 10.X for BMR on old target machines

Symptom:

When I perform a BMR using SLES 10.x recovery points to an old target machine, the BMR is successful but the target machine does not start successfully. Also, when I have recovery points from an SLES 10.x old source machine and I try to perform a BMR, the BMR is successful but the target machine does not start successfully.

In both the cases, I get the following error message:

No operating system

Solution:

Modify the boot disk MBR in a Live CD environment and restart the target machine.

Follow these steps:

1. Log into the target machine using a Live CD and locate the boot disk

   Example: /dev/sda

2. Run the following command:

   echo -en "\\x90\\x90"|dd of=/dev/sda seek=156  bs=1
   

3. Restart the target machine and verify if the target machine restarts successfully.

The SLES 10.x target machine successfully starts after a BMR.
