windows stuck at Cyan Screen with Rotating Dots...not able to get login screen

Hi Madhav,

This issue might have occurred due to corrupted system settings.

Let's perform a “Startup Repair” using Windows 10 bootable DVD or USB drive and check if that helps. Initiating repair from DVD may have different results.

If you don’t have the bootable DVD or USB drive, please refer to the steps in the article given below to create one and then follow the steps given below.

Create installation media for Windows 10

Once you have made the bootable USB or DVD drive, please follow the steps.

1. Insert the installation DVD or USB and boot Windows 10 from it.

2. In the ‘Windows setup’ page, select the ‘language to install’, ‘Time and currency format’ and the ‘keyboard or input method’ and click on ‘next’.

3. Click on ‘Repair your computer’ and select ‘Troubleshoot’.

4. Click on ‘Advanced options’ and select ‘Startup Repair' and select the operating system.

You might also require to change the boot priority in BIOS in order to allow the computer to boot from DVD.

Note: Modifying BIOS/ complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.

Kindly let us know if you need any further assistance with Windows. We are glad to assist you.

Thank you.

Perform In-place upgrade by downloading and installing Windows 10 using Media Creation Tool and check if the issue is resolved. Select Keep all the apps and files option to retain the apps you have downloaded and saved files & folders on your PC.

An In-place upgrade is the final alternative before you have to reinstall the operating system. It is the upgrade performed on the same version/edition of the operating system to repair the damaged files or to restore the lost files of the operating system.

Note Performing a repair installation will not damage files and applications that are currently installed on your computer.

Follow the steps below to perform In-place upgrade:

1. Copy the Windows 10 ISO image onto a bootable media and insert the same on the computer.

2. Click on the .exe file and follow the on-screen instructions.
