Disclaimer: You will need administrative privileges to run these commands. In addition you will need to open up a command prompt with those rights to make the changes. Last but not least we will be working with the entries regarding the boot loader. If the entries get fouled up for some reason and your computer no longer boots then I am not responsible. You have been warned.
Update: The following instructions were updated on 5/7/2010 because some of the directions were wrong. I found on my last cloning job that the entry that maps the recovery entry and the options for that entry are different by one character. Usually incremented up one it is the 8th character in most cases. I show it below in the examples but the actual command string examples fail to show that and I don’t indicate it in the base command lines. I have corrected that below.
After a drive clone (and possibly in other scenarios) you may end up being unable to boot the “Repair Your Computer” option. It may give you an error that it failed to locate the specified partition or device. Here is what you need to fix the issue. Just to show you what I am referring to I will give you a screen capture of the result when you try and use that option after a clone. The issue was replicated under a 2 drive scenario using vmware. One was a 40GB and the other was an 80GB.
