2. Underscore problems on the E63

   Thanks for that suggestion. Yes I have tried that and it

   OK. It seems like I need to do a step by step:

   Menu > Installations > Messenger > Open Messenger try to type in my domain name which includes an underscore that I am unable to type. I've tried pressing the Ctrl, Chr, button with the grey and white triangle, with the 'K' which has a dash, and by pressing
   them on there own. Nothing.

3. Black screen with underscore after blue screen?

   Unfortunately, I cannot even get the computer to function enough to do this. It is completely unresponsive, a black screen with the only thing on the screen being a white underscore. No dots appear on the screen.

   Blank screen with flashing underscore

   Hi,

   Thank you for writing to Microsoft Community Forums.

   I appreciate the efforts taken by you in resolving the issue. I understand that you get a black screen with flashing underscore. I'll certainly assist you with the issue.

   However, please let us know the make and model number of the computer that you are using.

   As you have already tried changing the Boot order, I would suggest you to refer the troubleshooting steps mentioned below and see if that helps.

   Method 1: Rebuild BCD

   You may want to try rebuilding the BCD file and see if that helps. Refer the steps mentioned below:

   1. Create a bootable media and boot the PC using the
      media.
      
   2. On the initial setup screen, select the language and other
      preferences and click on Next. (If you don't see the setup screen, your PC might not be set up to boot from a drive. Check your PC manufacturer's website for info on how to change your PC's boot order, and then try again.)
      
   3. Now, click on Repair your computer.
      
   4. On the System Recovery Options screen, select
      Troubleshoot> Advanced options > Command Prompt.
      
   5. Now type in the commands and hit enter: BOOTREC /FIXMBR

      BOOTREC /FIXBOOT

      BOOTREC /scanos

      BOOTREC /rebuildbcd

   6. Restart the PC.
      

   Method 2: Startup Repair

   If Rebuilding BCD doesn't help, we can perform a Startup Repair on the computer and check. Refer the steps mentioned below:

   1. Boot the PC using the bootable media.
      
   2. On the initial setup screen, select the language and other
      preferences and click on Next. (If you don't see the setup screen, your PC might not be set up to boot from a drive. Check your PC manufacturer's website for info on how to change your PC's boot order, and then try again.)
      
   3. Now, click on Repair your computer.
      
   4. On the System Recovery Options screen, select
      Troubleshoot> Advanced options > Startup Repair.
      
   5. Restart the PC.
      

   Let us know how it goes.
