Windows not working after Ubuntu installation

Question

Hello,

I am using a Dell laptop Inspiron 3000 series. For my work, I tried installing Ubuntu 20.04 LTS. The installation said it was complete and I tried restarting my computer. However my screen displays a message "Diagnosing Repairs" for some time and then the next message is a blue screen ( I have attached the screenshot for your reference).

I don't know what went wrong, but I would like to remove the ubuntu installation and get my PC reset back. I went through DELL help articles, but it wasn't providing any solution to my problem.

In case you do know how to fix this issue, please help me out.

(NOTE : In case this article is inappropriate in this support forum, please message me and I will remove it immediately. I did not know whom to ask for help. That's why I have posted here)

Did you change the system from RAID on to AHCI or RAID off? That will break the WIndows install.

To reload Windows 10, see

I don't think I had changed any option named as RAID at all. I went through your article, but they all require you to open the start menu (which itself is not possible to reach in my case). I thought of using installation media for Windows 10 and use it maybe for diagnosing. I don't know if this right way. Please let me know your thoughts and advice.

You need the recovery media if the system won't start up. You can either do a full recovery (start with link 7 above) or try a repair:
