Unable to load Windows. Error message The Endpoint Format is Invalid

By 4U Computers Support ·
Does anyone have any advise on how to solve this problem.
The computer has windows XP Hm. When powering on it starts to load windows (the Windows screen never appears) but then displays a black screen witn a msgbox with the error "The Endpoint Format is Invalid". Clicking on OK or closing this msgbox reboots the computer.
Trying to boot to safe mode produces the same error. I have tried to use the Windows XP Restore disk but part way through checking the system the screen turns black and I am left at a dos prompt.
I can boot from a boot disk and get access to the C:\drive. C:\drive is Partitioned.

I hope this is the right place for this query.
Thanks

I have not seen this before

I have not seen this before. But, I did a quick Google search to research it for you (1). It appers that this is related to networking. You should also be seeing lsass.exe in the error message...are you?

Can you boot to safe mode without networking?

You mentioned you tried "Windows Restore". Did you really mean "Windows Repair"? If you haven't tried "Windows Repair", suggest you try that. There is a good how-to on this here (2).

This is very odd. It may be a hardware problem. How long have you been using this computer before this problem occurred?

Error message. The endpoint format invalid

by junedoug In reply to Unable to load Windows. E ...

I got over this prob by doing a safe start (as soon as the first screen comes up that does the diagnostics keep pressing F8 at about one second intervals) This will then give you a dos type screen which has options. The option I chose and worked for me was the one that said something like 'start using the setting that were last successful' (or something like that. Select that and enter.

Thanks
I did try booting in safe mode and in all modes including last successful login. I have since solved by booting from the XP CD and doing a system restore.
Thanks for everyones comments.

A FIX THAT WORKS

by adambeaz In reply to Unable to load Windows. E ...

whats up everyone, i have run into this problem on many differnt computers and here is how you fix it.

If you can boot into Safe Mode:
right click on "My Computer"
go to "Properties"
Click "Advanced"
Click "Settings" in the Performance Box
Click "Advanced"
Change Memory Usage to "Programs"
Reboot

If you cannot boot into Safe Mode:
(I have not tested this, so use at your own risk)

But hey, you cant boot anyway, so what do you have to loose.

Use recovery disk to get into recover console or find some other way to run a command prompt on the drive that is having the issue.

The type the following command:
REG ADD HKLM\System\CurrentControlSet\Control\Session Manager\Memory Management /v LargeSystemCache /t REG_BINARY /d 0x1
reboot

That should change the same key that was changed in the first steps

If this works, signup for an accoutn here and let us know, this windows issue has gone on long enough, and Microsoft is not addressing this widespead problem, we need your feedback.

Peace,

Adam

Thanks!

by sombreero In reply to A FIX THAT WORKS

Nice work Adam!

This was very easy to do and it got the problem solved.

So if you are having similar problems and you are able to reboot to "safe mode".

I strongly suggest you do just like Adam instructed.


Once more thank's :)

Reared it's head again...

by support In reply to A FIX THAT WORKS

It seems this error has come back again. The closest I can tell, some driver or update issue gave a handful of folks this error in late 07. I had a user bring me a laptop yesterday and it was absolutely locked down with this error. I have no access from any normal or safe boot. I used a tool to get in and apply adambeaz's memory management adjustment. I used BartPE to delete the pagefile. In short, I tried every trick I came across from the 07 era...to no avail. I'm working on a WIndows repair but it has hanged at the same "installing devices" point two times now. My next step is to get in with BartPE, pull the user files off and fdisk.
