Blue screen on laptop
Although Microsoft Windows has come a long way since the way-back days of Windows NT in the 1990s, the latest incarnations of Microsoft Windows still suffer from the same "blue screen of death symptom" that the original Windows versions such as Windows NT suffered.
The blue screen of death
If your windows laptop or tablet displays a blue screen similar to the one above on startup, it means that something seriously went wrong with the Windows startup process and Windows was unable to load. This could be a faulty driver, incorrect driver installed, hardware issue or corrupt files on a disk drive (such as the Windows registry which is common). Usually the fastest way to resolve the issue is to use system restore to restore the computer back to an earlier point in time before the problem started.
How to recover from the laptop blue screen
Recovery can often be easy. The first thing you need to do is to see the blue screen of death message on your laptop. Often the blue screen flashes up too fast to view so the first thing you need to do is tell the computer not to restart automatically on a laptop blue screen error.
Press F8 as soon as the computer is switched on, you may need to press it several times. When Windows starts to load you can select "disable automatic restart on system failure. More information can be found here.
Once you've disabled automatic restart, the next time the system restarts the laptop blue screen message will stay on the screen. At the top left corner will be a stop error message with a set of numbers starting with 0x (zero x). Make a note of this number. Let's say the stop error code was 0x000000ED.
Perform a google search for '0x000000ED', now you'll find the Microsoft support page for this stop message, in this case the message is telling us the boot device is inaccessible. Perhaps a hard disk is failing or some startup system files became corrupted, which is common on Windows systems that were not shut down correctly due to crashing or locking up or some other reason.
Generic ways to troubleshoot
Inserting the Windows installation CD and performing a repair installation can often help repair the problem. Performing a disk repair (Windows 7 and above) can often fix corrupt files on a disk and allow Windows to startup. Performing a system restore can also replace damaged system files with those from a last know good startup. To access all these options check this instruction.
Options for repairing Windows NT or XP (including 2003 server)
Those of you that have versions of Windows older than Windows Vista will not have access to the repair tools on the Windows CD when starting up, although you can perform a repair installation which will often fix the problem. For more advanced tools please search Google for Hiren's Boot CD, download the CD and start it up, You can select from the menu Disk Tools and then NTFS Tools and then select NTFSDOS (read and write). Whilst starting NTFSDOS will ask if you want to run a CHKDSK, say yes. This will fix any corrupt files/disk issues that you may have, provided the disk drive is not physically failing on all sectors.
