Windows 10: Black screen with horizontal dotted lines on HP pavilion G6 when booting from a GPT flash drive

Black screen with horizontal dotted lines on HP Pavilion g6 when booting from a GPT flash drive I tried to boot before from GPT and the same screen shows but I used to press a bunch of hotkeys to bypass it wish I completely forgot. Yeah I know to fix it boot on MBR but I whent to boot GPT cuz it's better and I know I can boot on GPT but I don't remember the Hotkeys for it

I get Black screen with dotted horizontal lines while performing a clean flash

I have a HP Laptop running on windows 10.

I want to do a clean flash the windows

So i created a bootable usb using rufus.

But when I select the usb in BIOS.

It shows a black screen with horizontal dotted lines

And nothing happens after pressing any key it just restart.......

Please Give me any solution as soon as possible

horizontal black line on screen

Without you having posted a screenshot of it, it may point to either corrupted graphics drivers or a possible failing hardware part.

We don't know if the horizontal black line is at the top, bottom, middle or where on the screen or the thickness of it or anything else about it.

Hi

the line is fine, straight, black, horizontal, black and about 6cm long. It is situated 3cm from the bottom of the screen, and just to the right of centre. I have tried to take a screen shot of it but when I paste to Word it does not appear on the image.

 

Black line (horizontal) on the screen

Thanks for replying, actually the problem is a black single horizontal line, not a black screen.
