First thing to try: see If you can't change it back if you boot into Safe Mode.

If not it's time to go back to factory conditions from the recovery disks you made, the recovery partition or the refresh or reset options offered after you boot from your Windows 8 install or recovery disks.
Since all of that is rather depend on the make and model of your laptop, I can't be more specific.

In reply to: re

If you can go into the advanced options, try System Restore first. That should restore the registry that contains that fatal value of 256 MB. gives other options to try.

Also somthing to try: edit the registry from the command prompt. That's discussed in
But you have to find out where that 256 MB is stored. It might be in some other place than the registry. In older versions of Windows it was some ini-file, that you can easily edit.

In reply to: re

I found potential problem.In cmd i typed "bcdedit /enum all /v".In the second section i found "truncatememory. 0x10000000"is that the way it should look and if not how should it?

your laptop lost it's boots?

Maybe it wanted sneakers instead. Wink

I ran into the same problem and solved it...

The correct syntax should be:

bcdedit /deletevalue {default} truncatememory

where "{default}" is the name of the identifier where "truncatememory" is listed by "bcdedit". Also set it to something else by typing:

bcdedit /set {default} truncatememory 0x100000000

Remember to always take a backup before you start:
bcdedit /export c:\bcd_backup
To restore it type:
bcdedit /import c:\bcd_backup

and a help file can always be found when typing
bcdedit /?
or more specific help about an option:
bcdedit /? <option>
e.g. "bcdedit /? /set"

Now my Windows is booting without a BSOD..

Thanks Starchild for sharing your solution !! It worked just fine for me and am really really glad that I came across this thread. Thanks to all the people associated with this forum where such solutions are shared for really nasty issues and which are not provided by the manufacturer/creator of such softwares !!!

In the command Prompt, type bcdedit
Look for the Windows Boot Loader entry that contains an item named truncatememory
Note the identifier for that entry, it may be {default} or {current}, or may be a long GUID like {8eea9b82-d5b1-11de-9d24-80972e3a13c7}
Enter this command:
bcdedit /deletevalue identifier truncatememory
replacing identifier with the correct one you noted for that entry.

The screen shot is when booted to Safe Mode with Command Prompt.
Accessing the Command Prompt by booting to the DVD and choosing Repair your Computer, the identifier for that same entry is shown as {default}

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
