Advanced Recovery Options
If you choose the advanced options on the recovery screen, you will have several more options.
If you use System Restore to take snapshots of your machine, you will have the option of restoring back to a specific snapshot.
Another option is to restore to a system image. This is similar to using a recovery partition, but instead of losing any apps installed, the system image will include all applications and data at the time the image was taken.
Similar to earlier editions, you can also perform a Startup Repair. This will run through some common startup issues and attempt to resolve them automatically.
If you really know what you’re doing, you can also access the Command Prompt from the Advanced Options menu.
Hopefully with the plethora of options available to you, you will have good luck repairing your Windows 8 machine. Good luck!
