This question is concerning the disc that Windows 7 users can make by going to Backup and Restore > Create a System Repair Disc and then burning the disc.
Windows says this disc can be used to boot the computer. However, you won't necessarily be able to boot your Windows 7 OS from the hard drive. When I had a problem recently (shut down system and when restarted I got a DOS message that said "Boot MGR missing") this disc did nothing in an attempt to make a repair. From the System Recovery Menu you see here when you boot the CD:
I selected "Startup Repair" and it couldn't fix anything. I ended up cloning my hard drive from a backup.
"Are there problems that Startup Repair can't fix?
Startup Repair can only fix certain problems, such as missing or damaged system files. It can't fix hardware failures, such as a failing hard disk or incompatible memory, nor does it protect against virus attacks.
Startup Repair isn't designed to fix Windows installation problems, nor is it a backup tool, so it can't help you recover personal files, such as photos or documents. To help protect your computer, back up your system and files regularly. For more information, search for "backup" in Windows Help and Support."
So here's my question: How do you create a bootable CD that has everything you need to fix the Master Boot Record so that in the event that your boot files are damaged, corrupted, or deleted (and of course you can't boot your system from the hard drive) it will either fix the files on the hard drive or at least still boot your OS from your hard drive?
