Two BSOD issues; 1. Missing ntoskrnl.exe and 2. 0x00000019

[Confused Mom]

I have two issues going on with my HP laptop. I am currently running Windows 7 64 bit.

I keep getting the BSOD at random times with 0x00000019 under technical information. Most times if I hard reboot, it will bring me back to my desktop. I'm not sure how to fix this and would appreciate your help.

The second issue I ran across when trying to upgrade to Windows 8. A BSOD comes up there telling me that my PC needs to be repaired because the kernel is missing or contains errors. The file it is looking for is: \WINDOWS\system32\ntoskrnl.exe and has an error code of 0xc0000221. I can't find the disks that came with the computer...... can anyone help????

Hi -

0x19 = bad pool header; cause could be hardware or software

0xc0000221 = checksum mismatch - there is an integrity problem with a file

ntoskrnl.exe = Windows NT Kernel - system cannot run without it

This is for XP, but applies here as well - http://support.microsoft.com/kb/314474

You are now stuck with the 0xc221 - Windows 8 upgrade? i.e., cannot return to Windows 7?

Where did the Windows 8 upgrade disk come from?

Thanks for replying.... I saved the windows 8 upgrade as an ISO file to a DVD from the Microsoft download page so luckily I was able to get back to where I was in Microsoft 7. However, I did pay for the windows 8.

How can I fix the kernel error?

Hi -

The 0xc0000221 checksum mismatch on the NT Kernel indicates there is a likely problem with the Windows 8 upgrade DVD itself, e.g., the download may have been corrupted or perhaps the DVD burn was not 100%.

I would suggest to re-burn the Windows 8 ISO onto a DVD-R using ImgBurn.

Step #2 only for ImgBurn instructions - https://www.sysnative.com/forums/hardware-tutorials/4072-hard-drive-hdd-diagnostics.html#post29394

If that fails, contact Microsoft for replacement Windows 8 Upgrade media -

Hello Confused Mom,

You should follow jcgriff2's instructions.

I would like to point out that there is a possible hardware issue at play here and possibly a corrupted Windows installation.

If you wouldn't mind, I would like you to run a full memory test and hard drive test as I will outline in the following instructions.

Let's start with the memory test.

We are going to run the following tests outside of the Windows environment, so I would like you to download Memtest86+ from the following link.

Memtest86+ - Advanced Memory Diagnostic Tool

You will want to select the CD image (.iso) version of the file.
Burn it to disk per jcgriff's instructions earleir.

• Insert the Memtest86+ CD in your computer's optical drive.
• Boot the PC to the Memtest86+ CD.
• Memtest86+ will begin immediately (and automatically).
• Let Memtest run for a minimum of 2 to 4 hours or until you see memory errors. Errors show up on the bottom half of the screen highlighted in RED.
• Please report the results of the memory test.
