I downloaded and used the Boot Repair Disc on source forge.net It installed and I was told to remove the disc and close the tray before running a restart. I clicked OK it shutdown fine. But on restart it was just like after quite a few Windows Updates after restarting a dark grey/black blank screen and no flashing hard disk drive light for nearly 4 hours now. My question is has this system crashed or is this normal. I left the computer on all night from yesterday 17.25 hours still no Windows but a black screen. Installed the disk again (nothing) but after a restart filled the screen with lines of code and description.
