Can't boot and get winload.exe and ntkrnlpa.exe errors

My laptop suddenly refused to boot a while ago. It might be a hardware problem since it mentions something about disconnecting all USB drives when I try to repair. I could enter the advanced boot options using F8 in the beginning but can't anymore.

Anyway I finally got a installation CD which can run repair. I tried to repair but it said it couldn't do it. So I tried to manually copy the winload.exe file to c:/windows/system32/ it worked the second time.

I tried to boot again and this time it said that it had an error with ntkrnlpa.exe. I tried to copy in the same way as I had the winload.exe file but apparently the fiel couldn't be found or copied (something like that.)

I've also tried using a restore point but it said there were none. I tried to use the bootrec/fixboot command but it hasn't worked.

My HD is split into two internal drives C: and D: the system is installed on C: If I do a clean install would drive D: be overwritten too? I was also wondering whether maybe there was a bad connection or a problem with the connection of drive D:

So anyone have any ideas?

    Hmmmm... a restore point? I don't recall it asking me to establish a restore point since the problem started. I have however got some cds with restore points from almost the first month that I had the laptop.

    I'll try copying those files and get back to you with the results.

    They don't seem to be accepting the commands when I try to copy the files. It says the parameters are incorrect or something of the sort. Or it just doesn't accept the command.

    Hmmmm... how do you get to start>accessories>system tools>system restore without logging in?

  • midiank Feb 07, 2009

    I guess I have to do that from the installation cd?

    The stuff which I want to keep is mostly on my D: drive so I guess it should be fine.

  • midiank Feb 07, 2009

    Hmmmm... I've just realised why some things weren't working. I have found out that instead of just having my c: and d: drive along with the cd drive there are two other drives in my computer. I'm not sure whether they're partitions or what they are.

    At anyrate it seems that my computer is trying to boot from a drive x: called "boot" instead of drive c:

    Could it be that this is the problem? Also I can't help wondering how on earth those wierd drives suddenly popped up.

    :) my bad..when you said you tried a restore point I assumed you were in..ok well the last resort is installing the original disc that came with the operating system. Hang on about 15 minutes though, because I am pretty sure that if you load the original disc it deletes the partitions, hence, everything will be lost. Let me ask somebody real quick just to double check..

    On the first page after you click on System Restore in Accessories there are two options: one of them is Create a Restore point. Just pick a date and it will reboot and voila you are in the past

    Yes, if you go into start>accessories>system tools>system restore in my experience you can establish a restore point then reboot and you're back in time...

    Before you re-install and lose everything I want to know about the restore..didn't it ask you to establish a restore poinit? Did you try to establish one?..Also as far as the files to copy over to boot, they are NTLDR, BOOT.INI, NTDETECT.COM and NTOKRNL.EXE, they are on your disc either under i386 or windows. If you can copy those to your C:\ then it will boot. Try those things first and let know.

If you reinstall windows just make sure you do it on the partition it was already installed. If it was not installed in D as long as you do not delete or format that partition you will not lose that data or the partition.

As for your errors you will need to reinstall windows if you cannot repair the already installed partition.

How to enable bluetooth

Your computer has to have a bluetooth radio. You can check
Control Panel > System and Security > Device Manager
Do you see a Bluetooth Radio listed?

If not, you don't have BlueTooth on your computer so you will have to add a BlueTooth device by plugging one into a USB port.

If you have a BlueTooth radio, go to Control Panel > Hardware and Sound > Device and Printers > Add a Bluetooth Device

This option is used to connect a blue tooth device (e.g. bluetooth headphons) to your laptop through your bluetooth radio.

See this Windows web page for more information.
Set up Bluetooth enabled device

I will respond to any additional questions you have.

How do I get the battery out of my acer laptop

Your Model of Aspire has a different battery release method, see attached pic on how to do it. This is a pic from your User Manual, you can download it from here Download Acer Aspire E1 572

Button keeps blinking

It sounds like it could be either the battery is going bad and not holding a charge or the adapter is. I have had really good luck with similar problems going to places like Batteries +, and large electronic retailers, and my favorite the small local mom and pop computer store; where I end up asking them If I could try one of the adapters from the floor model to eliminate if is a faulty adapter. Other then that I'd if its not out of warranty contact Acers online chat support at

How to install Anti virus on my desktop

Following the steps to install antivirus on you pc.

Compare antivirus software. Look at the features and benefits of each. Read reviews from authoritative editors from magazines such as "PC World," "Smart Computing" and "PC Magazine." Editors who write for these magazines typically test antivirus software as an unbiased outsider and write about both the good and bad sides of antivirus software. For example, the editors at "PC World" recommended Avira AntiVir, Avast Antivirus and Panda Cloud Antivirus in an August 2009 article. Visit the websites of each antivirus program to view screen shots and descriptions of how the program works. Make a final decision about which antivirus program you want to install.

Navigate to the website of the antivirus program you've chosen. Go to the "Downloads" section of the site if you're obtaining a free antivirus software. Click on the "Purchase" section or "Buy" button if you have chosen licensed software; pay for and complete the transaction. Click the "Download" button or link for the antivirus program. Save the file to your computer desktop or to a computer directory or folder which you can easily remember.

Find the antivirus program file you downloaded on your computer. Double-click the ".exe" file (which is an executable file that will install the antivirus program). Once you double-click the ".exe" file, the installation process will automatically begin. Click "Continue" or "Next" on each screen to complete the installation process. Enter your name and contact details if registration is required. Follow any other on-screen prompts to complete the antivirus program installation. Restart your computer if necessary.

Freezes on the warm boot screen MC9000

This can be for a number of reasons.

First thing would be to try and cold boot the device:-

Remove battery half way, hold power button and trigger, push battery in fully until click and then release power and trigger

If that fails next thing would be to try and re-flash the operating system. This is done by using an SD card and loading the latest operating files onto it. The SD card slot is located under the keypad. A cross head screwdriver is required to remove the keypad. Search on symbol software download site for the latest. The download also has a readme with detailed instructions. Once the files are on perform a cold boot.

Remove battery half way, hold power button and trigger, push battery in fully until click and then release power and trigger. Drop the terminal in a cradle so that it runs on external power.

Hope this helps.

If you need any more help then please do not hesitate to contact us:-
