I am workng on a Compaq laptop with Windows Vista. On boot, I get the Compaq logo and then just a black screen and blinking curson up in the left hand corner of the screen. There is nothing plugged into the computer. I have tried repair from a Vista boot disk and it says nothing is wrong. Ran full diagnostics and all is ok. I installed Ubuntu and if I now choose to Boot from Windows on the opening screen then it boots fine. What is wrong here? I want to now remove Ubuntu and have it boot to Windows. FYI- It would not boot to safe mode and system restore did nothing.
