I installed Ubuntu a few days ago. Due to some error my hard disk was erased. Now I am trying to install Windows 8.1 again, but I am getting this error:
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. Status: 0xc000000f Info: The boot selection failed because a required device is inaccessible.
