I have a system of Intel Core 2 Duo and 2 GB of Ram. It has a very long time gone when my first hard drive failed and my system does not start. But now again I am facing a similar kind of issue. I am getting a error saying Disk Boot Failure Press Ctrl + Alt + Del to restart. At first I had successfully formatted my computer and made things worked. But now the same is not happening at all. What does this error actually means. Is some files of Windows is getting misplaced. I am just looking for the exact explanation of this error. Does this is due to low ram.
