I recently booted into Ubuntu 12.04 for the first time and had great difficulty doing it. In the process I may have deleted the boot path back to Windows 8. I'm not sure I just really wanted Ubuntu, but now I feel like since this should be a dual boot. I have the right to get back into Windows 8 if I ever wanted to. When in grub I can select Windows 8 to boot into, but an error screen pops up which says:
Windows Boot Manager
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.
