Windows cannot start, NTOSKRNL.EXE missing or corrupt

Asked By Michael Hall 240 points N/A Posted on - 05/27/2011

 

 Hi all,

Every time I boot my PC, I always get this error; “Windows could not start because the following file is missing or corrupt: system32ntoskrnl.exe. Please reinstall a copy of the above file".

I tried to fix this problem with an emergency System Repair Disk but all of my attempts failed. I also tried booting while holding F8, and F7 keys but it all failed. The system restored to an earlier point but it could not be accomplished either. I tried to use the recovery console to copy my files across and this was the pop up error message, "access denied".

The message from the check disk function stated; “the volume appears to contain one or more unrecoverable problems". When I tried to explore the files on Drive C, an error message appeared; "there is no floppy disk or CD in the drive." I got a very important and classified data on this computer and I just can’t afford to lose it.

I can’t load another windows operating system disk because the disks and partitions are not visible. My computer specifications are: Motherboard: Asus M4A785-M Power supply: 550w ultra Integrated ati RADEON hd 4200 gpu CPU: Phenom 9850 2.5 GHz quad core RAM:2 sticks of Hynix 1gb 2Rx8 pc2 – 5300U – 555 12, 2 sticks of Hynix 512mb 2Rx8 pc2 – 5300U – 555 12. All the RAM was recycled from my old computer but were still working.

What should I do?

Thanks!

Only recovery can solve the problem. You can follow these steps:
 

• Insert CD of Windows XP in the computer and start it.
• After loading all the files, the window will appear and then click the repair button,
• Then select the window installation which you prefer.
• Then type bootcfg or rebuild and push enter.
• When the windows installation is done, then this will be displayed.
• The system will ask to add the installation for the boot list. Then you should press Y button from the keyboard.
• The computer will show Load Identifier, here, you should type windows XP.
• Then computer will  enter into operating system Load options, nothing will be written in this field. It should remain                             blank.
• When Windows XP has been successfully loaded, boot.ini file will be modified and shall remove the incorrect entries only.

If the above method will not work, then you can try this:

• Start windows using the CD of Windows XP and boot from the CD by pressing any key when the computer asks you to.
• When the loading process is finished, press R.
• Now, you are in the recovery menu, select the installation and press enter.
• Then log into the Admin account and give the password.
• In the recovery menu, type any one of the commands.
• When the message is received to re-write the file, then, you should press Y from the Keyboard.
• Then click exit and press enter to leave the DOS.

I hope this will help you!

Thank you.

Hi!

Well, if the rescue disk can’t help, then the only thing left to do is to reformat your hard disk. You said you have important files in your hard disk, and you need to get that first before reformatting it. You can follow one of these options to back up your file.

Use another computer and save your hard disk to that computer. Both the computers that you use will detect your hard disk automatically. When you're finished installing your hard disk, it will pop up a message that you have to restart your PC. So, restart your PC, then go and browse your hard disk, copy and save all your important files in it. When you have copied all your files, you can then format your hard disk and set up the OS you want to use.

If that won’t work, then use this other option:

Note: This option is risky. If you are not familiar with this, then you have to research first to have a deeper understanding about it. Visit this link for more info:

Well, it’s not really that risky, all you have to do is to use a data recovery and scan your hard disk to view all the data that are stored in the hard disk, but the percentage of being successful on recovery is very slim. If that happens, all you have to do is to first format your hard disk before you run a data recovery on it.

YES! You have to format the hard disk before running a scan for data recovery, that’s the risk that I’m talking about. Now, it’s up to you if you want to do the second option.

Hope this helps.
