I have Ubuntu configured to dual boot on my Windows 8 laptop. When I first installed it, I partitioned ~100GB for Ubuntu and left the rest to Windows (I might've messed up the partitioning.). Now when I try to boot Windows 8, the Windows Boot Manager tells me it has failed.

Windows failed to start. A recent hardware or software change might be the cause. To fix the problem: 1. Insert your Windows installation disc and restart your computer. 2. Choose your language settings, and then click "Next." 3. Click "repair your computer." If you don't have this disc, contact your system administrator or computer manufacturer for assistance. File: \Boot\BCD Status: 0xc0000001 Info: The Boot Configuration Data for your PC is missing or contains errors.
Any tips on how to fix this? I'm going to try to repair it with the installation disk, but I'm worried that some of my data won't be able to be recovered.
