I have been asked to try to fix a friends son's laptop. It is a Toshiba Satellite L655-S5150. When powering it up I get the Toshiba start up screen and I can hear the fan working. It seems to proceed normally then a screen comes up that says windows failed to start. A recent hardware or software change may be the cause. I am not aware of any changes to either one.
I get two choices. Launch start up repair(recommended) and start windows normally. With either choice it attempts to start up but then the screen stays black. I can move the cursor around normally but that is as far as it goes. I can get to the bios using f2. The version is 2.30 which appears to be the latest. I can also get to the advanced options. I have tried the repair your computer, safe mode, safe mode with networking, and safe mode with command prompt but it always ends up with the black screen. I am also able to get the the boot menu.
They don't have a boot disk or recovery disk for me to use. I have tried using another monitor with the same results. I have also tried unplugging the computer, removing the battery and pressing the start button for both 30 and 60 seconds with no success. I have done a little research and it sound like he may have the zero access root kit. I thank you in advance for any help.
