Toshiba L855 wont boot even with USB. black screen with white cursor.

[chandan.mountainlover]

my problem seem similar but slightly different. I tried to do factory reset due to driver compatibility issues with windows 10. My machine came with windows 7 pre installed but windows guys lured me to update to windows 10 . whilst doing it, I got a message that something has gone and the process aborted, and then when i tried to restart, after toshiba logo, i get a BLACK screen with a white cursor on top left corner. if we press any key then just a beep sound comes. Bios is accessible but changing the order is NOT working. I have tried booting with a recovery USB and with a bootable Windiws 7 disk.. Nothing is happening. Any idea ? it's a L855 from Toshiba.
I have read all other discussions about boot issue bt nothing is similar is this one.

any help would be appreciated.

Try this....

Make sure you wait until the computer would be fully loaded before trying this, and not try it right away like you would to say get into BIOS. This needs you to actually be where you would be when Windows Explorer loads.

1. Press "Shift" repeatedly until the "sticky keys" window shows up.

2. Now click the the link there that will lead to the "Ease of Access Center".

3. Next click "Cancel" on the the bottom right corner of the "Set Up Sticky Keys" window.

4. From here you want to click "Control Panel" on the upper left corner (it should be right beside the "Make Your Computer Easier to Use" title.

5. Locate the "Computer Settings" menu and then choose the "Recovery" icon (make sure that your view of this is by either large or small icons for easier access).

6. Now click and open "System Restore".

7. Here you want to click next on the bottom right corner (a few times) until the button "Finish" shows up and then click it. (Just follow everything prompt that the window says which will lead you to recovering your previous system, in a certain time.

8. The computer will now do the work it needs to and then reboot.


If that doesn't work, you can try the following...

You can also try doing the Ctrl+Alt+Delete and see if you can get "Task Manager" to show.


If the "Task Manager" windows shows, then choose "New Task" and then type in EXPLORER. If the desktop shows up then you need to go into "Start", "Programs", then "Accessories" and finally "Command Prompt". (Or you can do a search for CMD.)

Make sure you load the "Command Prompt" with Administrator access. Then when it loads type in....

SFC /SCANNOW

It will do a file check.
