How to make a recovery disk for another computer?
At this point, I suggest you to download the Windows 10 ISO and create a Media Creation tool from another computer and then perform Automatic Repair using the same ISO media.
Refer to the following link: http://www.microsoft.com/en-us/software-downloa...
(Refer to the section Installing Windows 10 using the media creation tool in the above article for creating the tool).
Once you have the installation media, follow the steps:
- Start your computer from the installation media. Insert the disk or USB stick and restart your computer. If you see a message asking you to Press any key to boot from DVD, do so. If you don’t see the message, you might need to change the boot order in your computer's BIOS settings so that it first starts from the disk or USB. When you see the Install Windows page, tap or click Repair your computer link to start the Windows Recovery Environment.
- In the Windows Recovery Environment, on the Choose an option screen, click Troubleshoot.
- Click, Advanced Options and then click on Startup Repair.
- After this complete the repair and see if you are able to boot in to your computer.
Note: There will be no data loss by performing Startup repair. It will format c: driver and reinstall Windows 10. It will remove all the installed apps and updates.
Important: You might require to change the boot priority in BIOS in order to allow the computer to boot from CD/DVD or USB.
Hope the above information helps to fix the issue of unbootable Windows 10.
