Windows 7: System partition randomly jump to Backup drive

As David says you should be recovering using the image from the application's boot disk. If it's Win7 backup imaging then follow this: System Image Recovery.

As to how to move the System flag to System Reserved, Is this another internal hard drive? See if you can disable the storage drive in BIOS setup before running Startup Repair - Run 3 Separate Times.

If unable to disable or disconnect the storage drive - don't risk ruining your laptop if you're not confident of disassembly - then I would download Partition Wizard CD, burn to CD using Windows Image Burner, boot it to rightclick Storage drive, select Modify>Set to Inactive, OK. Apply step. How to Set Active/Inactive partition -Partition Wizard Video Help.

Next rightclick D to Modify>Set to Logical, OK, Apply. How to set partition as Primary or Logical with Partition Wizard

Now you have a Logical data drive which cannot be used to boot Win7, so confirm System Reserved is still Active, then run Startup Repair - Run 3 Separate Times until Win7 starts and has the System Flag on System Reserved.

Or once Storage drive is safely Logical, you can do a Clean Reinstall - Factory OEM Windows 7 to DISK0, deleting all partitions during the booted install. Make sure not to touch your data drive!

If its a windows system image, created with windows backup, reinstalling windows and then going to backup and recovery in control panel, use the option recover system settings or your computer. Then choose advanced recovery methods. Then click use a system image you created earlier to recover your computer. Works flawlessy every time when done that way.
