I have a motherboard with UEFI (Gigabyte GA-B75M-D3H with latest UEFI). I installed Windows 10, then installed Ubuntu 17.04 with dual boot option.

Ubuntu would boot, but due to no overscan options working for my LCD TV, I went to boot Windows. Windows proceeded to try to repair itself, and failed; startup repair fixes nothing. I want to find out how to boot Windows without wiping the hard drive.

  • Did you turn off fast boot in windows? – Arun Jun 23 '17 at 18:04
  • Yes, and in the UEFI OS type is set to "Windows 8" (Options are "other" (basically BIOS-style compatibility mode), and "Windows 8 WHQL" – XtremeHacker Jun 23 '17 at 18:09
  • What error did windows show – Arun Jun 23 '17 at 18:11
  • First "Preparing automatic repair" then "Your PC/device needs to be rapaired 0x000000e" – XtremeHacker Jun 23 '17 at 18:14
  • did you upgrade from win8 to win10. it appears the recovery partition is win8..... grub doesn't launch win10 for you? – ravery Jun 23 '17 at 18:14
  • Grub does the same thing, and this System was setup with Windows 10 by me, it has never had Windows 8 installed. – XtremeHacker Jun 23 '17 at 18:15
  • If you have windows installation disc Try this: boot from the disc and type Shift+F10 to get terminal then type bootrec /rebuildbcd – Arun Jun 23 '17 at 18:24
  • Just ran that, it didn't detect _any_ Windows installations. – XtremeHacker Jun 23 '17 at 18:27

    Please run the [Boot Info Script](https://sourceforge.net/projects/bootinfoscript/). This will generate a file called `RESULTS.txt`. Post that file to [a pastebin site](http://paste.ubuntu.com) and post the URL to your document here. This will give us more details about your configuration, which is required to base an answer on more than guesswork. – Rod Smith Jun 24 '17 at 13:32

I think you need to install boot-repair. type these commands in the terminal to install boot-repair:

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair

now launch the boot-repair by typing "boot-repair" in the terminal, Then click the "Recommended repair" button. When repair is finished, reboot and check if you recovered access to your OSs. i hope it will work. because it worked for me.
