At one point I tried to install Ubuntu onto my hard drive without a USB or a CD. It is a Windows 8 computer. It didn't work, so I eventually gave up and did it with a USB. Ubuntu works fine now, but whenever I try to boot into Windows, asks me if I want to boot into Windows or UNetBootin. When I click UNetBootin, it gives me an error message:
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 do not have this disc, contact your system administrator or computer manufacturer for assistance. File: \ubuntu\winboot\wubildr.mbr Status: 0xc000007b Info: The application or operating system couldn't be loaded because a required file is missing or contains error.
How do I get rid of the UNetBootin/Wubi option entirely?
