My computer boots successfully (especially with my new SSD) but I have now noticed a small white blinking underscore in the top left corner on a black screen during the boot process?
This occurs for around 2-3 seconds and I was wondering what it is there for and is there any way I could disable this feature if it is not essential for a faster boot?
