Windows 10: Windows 11 Lost Activation and cannot Reactivate after setting up Dual-Boot with Ubuntu

Greetings,I have an MSI Laptop - previously it had Windows 10 on it and I've recently upgraded to Windows 11. I did a fresh install of 11 as opposed to just upgrading, but it copied my license key over from the previous installation automatically, since it's all been on the same machine.Edit: To be clear, I have connected/activated the license previously on the machine. It "lost" its activation somehow by installing Ubuntu is my best guess, although none of the hardware in the machine has changed.I migrated a virtual machine I had in VirtualBox running Ubuntu onto a 2nd hard drive in the machi

Help with dual booting Win 10 and Ubuntu

This is your whole problem. What you should have done is to put GRUB in sdb1 and Windows Manager in sda1 so that Windows Boot Manager is in control.
So what suggested above will not make any difference. GRUB is still in control of booting process.
To fix your problem. You will need to:

1. Move GRUB from sdb to sdb1
   |grub2 - how to move grub boot from one partition to another in linux - Ask Ubuntu
2. Rebuild The Windows Boot Manager ie. create a brand new BCD to boot Windows 10.
3. Once done with steps 1 and 2 above. Windows will not know UBUNTU exists and vice versa.
   Depend on the priority set in the BIOS, it will boot directly into that OS.
   However, you can boot either one from Boot Menu (Using whatever key that your Laptop assigned to: F2, F10....)
   Since I hate Dual Boot and seldom boot into Linux, I will stop here.
   Now, go to step 4 to create dual boot.
4. Use Easy BCD to create an entry for dual boot with UBUNTU. Once done, you should get a nice GUI dual Boot Menu
   and it will boot directly into either Windows or UBUNTU.

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 Redirecting.
But it did not help me to remove my error. I will really appreciate your help in removing this error.

Thank you.
