Re: Ready to install dual boot ubuntu, but want to backup MBR. How/When?
While Clonezilla will certainly work, you might find it easier to restore later if you use a Windows app to backup Win7. Strongly recommend Macrium Reflect -- the FREE version. Download and install that on Win7, then use the option to create and burn a Linux Boot CD.
While in Win7, use the Backup feature to create and burn a Win7 Repair CD. With this CD, you can later restore your original Win7 MBR.
Also, when you do the partitioning in Win7 Disk Management, be careful to ensure that you do not end up with more than 4 Primary partitions. Doing so will automatically convert your existing partitions to Dynamic Disks -- something you do NOT want to do.
Once you have shrunk the Win7 OS partition to make room, use MR to do an Image backup to an external drive. That will also back up the Win7 MBR.
Ubuntu 16.10 Mate, Mint 18 Mate; MS Win 8.1, MS Win10 Pro.
