Windows 7 will not start, restarts boot sequence after 'Starting Windows' screen. Can not access system repair, or safe mode.

About a month and a half ago, I purchased a new Toshiba Satellite C650D laptop, as I was about to start university.

Everything seemed to be working fine up until about a day or two ago, when my computer began to work much slower than usual.

Last night, when I tried to turn on my laptop, everything worked fine until it got to the 'Starting Windows' page. From that point, the windows logo animation played continuously, without stopping. I restarted my computer, and I was faced with an option screen to either start windows normally, or run a system repair. I tried both options, neither of which fixed my problem. By starting windows normally, the same problem as before would happen. By running a system repair, it would come up with nothing.

I decided that I would put my computer down, and try to see what the problem was in the morning. When I woke up today, I started up my computer, and was faced with the same problem, except infinitely worse. By running windows normally, the 'Starting Windows' animation will play for about 3 minutes, the blue screen will flash quickly, and the computer will restart, and begin the same process over again in a continuous loop. By running a system repair, it brings me to a blank screen showing nothing but my cursor.

I pressed F8 at start up to run the computer in safe mode. This did nothing but bring me back to the same 'Starting Windows' problem. The same thing would happen by running any of the other options.

I have no idea what to do at this point. I'd like to make it clear that I DO NOT have any windows disk, and I'm likely too broke to buy one (I am a university student, after all).

Any help would be greatly appreciated.


PS. I'm not the very best when it comes to computers. So, if you could make your replies somewhat easy to understand, it'd really help me out a lot. Thank you.

You have to press F2 as it starts up, tap it until it says it is entering setup or similar.

Setup/Settings (BIOS/CMOS) often F2 so watch the screen (also F12 on Toshiba allows a
one time boot drive choice) - set the boot order to CD/DVD first - remember to set back


Sounds like a bad drive and needs to be replaced. Have it checked at a real computer
shop (not leeks and peeks at a Best Buy or other Big Box Stores) or the System maker's
Support. That the drive will not run in another computer tells the story.

The UNMOUNTABLE_BOOT_VOLUME bug check has a value of 0x000000ED. This indicates that the I/O subsystem attempted to mount the boot volume and it failed.

Important Information If You Have Received a STOP Code
If you have received a blue screen error, or stop code, the computer has shut down abruptly to protect itself from data loss. A hardware device, its driver, or related software might have caused this error. If your copy of Windows came with your computer, call the manufacturer of your computer. If you purchased Windows separately from your computer, Microsoft provides support. To find contact information for Microsoft or your computer manufacturer, Contact Support.

If you have experience with computers and want to try to recover from this error, follow the steps provided in the Microsoft article Resolving STOP (Blue Screen) Errors in Windows.

The following actions might prevent an error like this from happening again:

Download and install updates and device drivers for your computer from Windows Update.
Scan your computer for computer viruses.
Check your hard disk for errors.

BCCode: ED   0x000000ED  <-- read this though its likely hardware error*1236.html?order=date


The same repair methods listed in the 1st troubleshooter above still apply, check
the drive.

Hope this helps.
