If The BIOS is showing initial splash screen, and completing POST test correctly, but Windows Startup does not complete, and you are in one of the following situations:
- You get a black screen with a cursor blinking.
- You get a black screen with test or command prompt.
- You have a blue screen with a warning message.
- Windows keep restarting.
- Windows is freezing.
Any of the condition described must occur before getting to login
screen or to Windows desktop, or the problem is other than the one described here.
If you get a message saying Operative system not found you may also be in same situation. Only in that case the disk may also be physically damaged, and you may have lost your data, or disk may need replacement.
The conditions above usually tell us that the Windows system files needed for Startup
Windows cannot load the files anymore and will hang on with the cursor blinking.
When this happens you need to reinstall the operative system.
To start you can try loading the system in safe mode, by pressing F8 on Startup
If the computer is starting in safe mode, try doing a system restore to a recent date before the problem started. This will be faster than installing a fresh system, and most of your settings will be preserved.
You may find out that when the system does not load, most computer will not even start in safe mode.
Check also that there is no CD, DVD or floppy inside the computer, also disconnect any connected USB
device, apart mouse and keyboard, and attempt starting the computer again.
If all that does not work, then you will need to reinstall Windows.
Installing Windows is not a complicate operation, all you need is the computer recovery disk, or a Windows install disk valid for the licence number
printed on the Microsoft Certificate of Authenticity sticker.
If you use a recovery disk, remember to choose partial recovery, so that the original data contained in the hard disk won't be deleted.
Using Windows generic disk you will need to choose Update Recovery if asked, install the system on top of the same directory (eg: C:Windows), and you will also need to choose Leave System File Intact, when asked by Windows setup.
Using a Windows generic disk you may also need to install additional drivers, that usually are available for download from the manufacturer website.
Even choosing a partial recovery , or an update install, some of the installed software may be affected, and may need a fresh setup.
Another way to proceed is installing a copy of windows into a different folder (eg. C:/Windows000), and choosing to leave system file untouched.
This will reinstall system files hosted in root folder, and sometimes may bring back to life the old system.
In that case you will be asked what system to start from Windows boot manager on Startup
, your old system will be the second one.
Using this method is better to remove the new installation Startup
from boot manager after installing and testing that the old system is back at work. This is done editing the system hidden file Startup
.Ini, hosted in root folder. The file is a text file.
If you have important data inside the hard disk, it is always advisable to copy all data onto an external media. Even if the procedures described normally do not delete your data, when doing maintenance on a computer there is always the chance to loose data.
If the computer is not starting because of a system problem, the data can only be recovered using a boot disk, or physically removing the hard disk drive from computer, and connecting it to a different computer (an external enclosure may help).
This same instructions broadly apply to all recent Windows operative system, Windows seven setup is slightly different from the procedure described here.
