windows failed to start, no installation disc

I have a Dell Latitude D630 laptop that I purchased refurbished 2 years ago. Today it froze twice and when I went to restart it, a black screen came up with the following message:

Windows Error Recovery
Windows failed to start. A recent hardware or software change might be the cause.
If Windows files have been damaged or configured incorrectly, Startup Repair can help diagnose and fix the problem. If power was interrupted during the startup, choose Start Windows Normally.
-Launch Startup Repair (recommended)
-Start Windows Normally

I tried the "Launch Startup Repair" option and it brought me to a screen that read:

Windows Boot Manager
Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1. Insert your windows installation disc and restart your computer.
2. Choose your language settings, and then click "Next."
3. Click "Repair your computer."
If you do not have this disc, contact your system administrator or computer manufacturer for assistance.
Status: 0xc000000e
Info: The boot selection failed because a required device is inaccessible.

I then tried to start it normally, but it brought me back to the same screen. The problem is that I do not have an installation disc. Since I bought it refurbished, I am not sure if I ever got one, but either way I do not have it now. I do have a product key for Windows Vista on the bottom of the laptop (which is pretty worn), but the computer came with Windows 7 installed on it, not Vista. There is no product key for Windows 7 on the bottom either. Do I have to purchase a new Windows 7 disc, or some sort of repair disc? If so, approximately how much does it cost?


Hi Kylie,


Thank you for writing your query on Microsoft Community Forums.


Based on the description I see that you are not able to boot to the desktop in Windows 7 as you get an error message Windows failed to start”



To help you better please answer this question:

Have you made any recent changes on the computer prior to the issue?



I would suggest you to follow the methods to resolve the “Windows failed to start”.



Method 1:

Unplug all the external devices and try booting and check.



Method 2:


Check if you are able to boot in safe mode or not:


If yes, I suggest you to put the computer in clean boot state and check.


To help troubleshoot error messages and other issues, you can start Windows Vista by using a minimal set of drivers and startup programs. This kind of startup is known as a "clean boot." A clean boot helps eliminate software conflicts.
