Windows 10: Windows boots correctly, but with repulsive blinking cursor after dell logo

Hi, I have a little issue with my windows pc.When I boot my pc, after the dell logo, I get a black screen with a blinking cursor that only lasts for a few seconds, then the windows logo appears and the boots complete. The expected behavior is mostly the same but without the repulsive and seemingly temporary blank screen and blinking cursor.I first noticed this issue when I switched from bios to uefi I did this with the mbr2gpt tool and toggling uefi in the bios menu. I had intended to dual boot ubuntu, and the switch was supposed to be a prerequisite. I noticed decreased performance, longer

Black screen with blinking cursor

I run Windows 10 and have a black screen with a blinking cursor in the upper left corner. I can hit Control, Alt, Delete, and it reboots momentarily, show the Dell logo and F2 Setup anf F12 Boot Options in the lower right corner. Regardless of what key
I hit, it goes right back to the Black screen w/ cursor. I can't seem to do anything. Any suggestions?

 

Cursor blinking and strange behaviour

Hi,

Thank you for posting your query on Microsoft Community. I understand the inconvenience you are facing. I will certainly help you with this.

Before Proceeding Further, I would need some more information from you.

• Did you try connecting another mouse and check if this issue happens with it?
• What are the recent changes that you have made to the computer prior to this issue?

I would suggest you to try the following methods and check if that resolves the issue:

Method 1: Run the Hardware Troubleshooter

The Hardware Troubleshooter is an automated tool which checks the hardware connected to the computer for any known issues and provides the details on how to fix them. Follow these steps to run the troubleshooter.

• Press “Windows Logo” + “Q” keys from the keyboard.
• Type “Troubleshooting” in the search bar and press “Enter”.
• In the “Troubleshooting” window, click on “View All” on the left pane.
• Click on “Hardware and Devices”.
• Click on “Advanced” and then click on “Run as Administrator”.
• Click “Next” and follow the on-screen instructions to complete the troubleshooting process.

Now, check if you still face this issue with the mouse cursor. If the issue persists, then try the next method.

Method 2: Check the Cursor Blink Rate and adjust it if needed

• Press “Windows Logo” + “Q” keys on the keyboard to display the “Settings” search bar.
• Type “Blink Rate” in that search box and press “Enter”.
• On the “Keyboard Properties” window, reduce the
  Cursor blink rate by moving the slider to its left.
• Click on “Apply” and then “Ok”.

In future, if you have any issues related to Windows, do get back to us. We will be happy to assist you.

Thank you.
