When you start installing Windows 10 the PC will restart and it will not start the installation automatically, it will display an error and show a retry button. Once you restart your PC to fix for Master Boot Record (MBR), Windows 10 will restart its 2,699GB of download, wasting 8-10 hours of bandwidth which was used to download the install files in the first place.

- Boot from Windows 8 USB/DVD, or restart the computer while pressing the
- If you booted the OS using USB/DVD then at welcome screen choose “Repair Your Computer,” then go to “Troubleshoot,” else directly choose “Troubleshoot,” and then enter a Command Prompt and type the following command:
- Exit the command prompt.
- Remove USB and restart PC.
