Invalid partition
I would like to give the following advice in such cases.
Most boot problems are caused by a corrupted MBR. So the first and simple step is to rebuild MBR. The simple method is to use Windows 7 Startup Repair. At some point, you may have to run it three times.
If the startup repair fails, follow the manual method to recreate the MBR manually.
Use MiniTool Partition Wizard Bootable CD. This is an excellent tool for managing partitions and the best thing about this tool is that you get the bootable disk version.
You can download the ISO image and burn it to a diskette, then boot from that diskette. You will be prompted to select the program and screen resolution, then select the appropriate options. Then select your main partition and select Rebuild MBR
on the right side.
Sometimes, the Windows loader drive is not enabled and in this case, problems may occur during boot. We must therefore mark the partition as active. To mark the partition as active, go to Partition in the menu bar. Then go to Change and select Mark as active.
This option is sometimes grayed out. In such cases, you may need to define the partition as primary Then you should be able to get this option. If none of the options work, you should consider disk diagnostics to check drive consistency. Follow this article on hardware diagnostics.
These are only some of the proposed troubleshooting steps and the list is definitely not complete. If you need more help, visit the TWC forums.
