Windows 10: Is it possible to repair Win 10 boot screen with dual OS options?

During a fresh Win 10 installation (using the Alienware recovery tool), I left the USB thumb drive with the installer plugged in, and during a reboot the setup started from scratch. When I noticed it, I interrupted the setup, unplugged the USB key, and continued with the first setup. I then finished the installation.

Now, every time I turn on the PC, I see a screen which asks me to pick one of the allegedly two OS installed on my hard drive, even though only one is actually installed. I can tweak the timer to 5 sec so it doesn't take too long to start. But I wonder if there's a way to fix this boot glitch and get rid of this annoying screen.

Repairing Dual boot for Windows 10

Hello.

I had installed Ubuntu for a dual boot but ended up deleting it and the partitions. Now when I boot my system a black screen appears with the message:

"Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device completions.

grub> _"



I can get to Windows by typing 'exit'. How can I get rid of these extra steps to starting my computer?

There is another post that already asked about this exact problem but following the directions did not fix it for me (see link below). Is there another way to fix this problem besides booting from an install and typing "bootrec.exe /fixmbr" into the command
prompt?

Dual Booting with Windows 8.1


The procedure below will allow you to boot Windows separately or in dual boot configuration.
Here's what I recommend to do:

1. Disconnect the drive containing Windows 8.1
2. Install Windows 10 with one drive connected.
3. After step 2, reconnect the drive containing Windows 8.1
4. Boot up Windows 8.1. Open disk management and take a note of the drive letter of Windows 10 OS.
   NOTE: if you boot up Windows 10, then take a note of Windows 8.1 drive letter
5. Open Admin command prompt and type: bcdboot X:\windows where X: is the drive letter of Windows 10 (Windows 8.1 if you boot from Windows 10 in step 4)
6. Reboot the PC. You should have a dual boot screen.

NOTE: To break off the dual boot setting, Win+R->msconfig->boot and delete the none default entry on the list.

 

Uninstall Ubuntu Dual boot and Repairing Dual Boot in Windows 10

Hello.

I had dual-booted my Dell laptop which came with preinstalled Windows 10. I had dual booted with Ubuntu 16.04 by creating a partition on the disk. To remove this dual boot, i.e. I only wanted to keep Windows 10, I formatted the disk, drive F(in my case),
where Ubuntu was stored. But, now whenever I boot my system, a black grub screen comes with the following message:

"Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device completions.

grub> _"

Upon writing 'exit', I am able to enter Windows.

1. I wish to know the reason behind it and how it can be removed.

2. I found this site, Uninstall Ubuntu Dual boot, I went ahead and performed all the steps. But somehow
ended up with this error.

Also, I saw your reply on this thread Repairing Dual Boot in Windows 10.
But it did not help me to remove my error. I will really appreciate your help in removing this error.

Thank you.
