My computer cant boot from cd even if its bootable (I am using a disk with xp_rec_con.iso on it).

It all started when my computer had a power failure, ungraceful shutdown or aborted restart.  Then I got a message " WINDOWS ROOT>\SYSTEM32\NTOSKRNL.EXE IS CORRUPT OR MISSING". I tried to do what another person said to do.

Calling Jose or ElderL...

In the event this other person doesn't see this thread, I will try to help.

He gave instructions to burn a bootable CD using the ImgBurn program and that particular .iso image.

If all you did was burn the .iso file onto the CD, it won't work.

So, please tell us EXACTLY what you did. And tell us EXACTLY what happened. If there were any error messages, tell us what they were! Give us the COMPLETE TEXT of the message.

Also tell us the make, model, and model number of your PC. You might need to change a setting in the BIOS.

Power failures are notorious for corrupting your NT File System (NTFS), so you need to boot into the XP Recovery Console and run chkdsk  /r  until it reports no errors (that may take more than one pass).  You are on the right track though.

If after burning your CD as indicated below, you do NOT see the message:

Press any key to boot from CD...

Then you need to get into the BIOS in your system of unspecified make and model and adjust the device boot order to put the CD Drive as the first boot device.

If you see the same missing or corrupt message instead something is not right and you need to look at things more closely.  Sometimes there is an option on the screen when the system reboots to press a key to select a boot device (mine is F11) and then you can just choose the CD/DVD drive as the boot device.

If anybody wants to recreate these sorts of problems for practice, just pull the plug on your running XP system 4 or 5 times and you will all the message we know and love.



Here are my standard suggestions:

You can make a bootable Recovery Console CD by downloading an ISO file and burning it to a CD.

The bootable ISO image file you need to download is called:

xp_rec_con.iso 

Download the ISO file from here:

Use a new CD and this free and easy program to burn your ISO file and create your bootable CD:

When installing ImgBurn, DO NOT install the Ask toolbar.

Here are some instructions for ImgBurn:

It would be a good idea to test your bootable CD on a computer that is working.

You may need to adjust the computer BIOS settings to use the CD ROM drive as the first boot device instead of the hard disk.  These adjustments are made before Windows tries to load.  If you miss it, you will have to reboot the system again.

When you boot on the CD, follow the prompts:

Press any key to boot from CD...

The Windows Setup... will proceed.

Press 'R' to enter the Recovery Console.

Select the installation you want to access (usually  1: C:\WINDOWS)

You may be asked to enter the Administrator password (usually empty).

You should be in the C:\WINDOWS folder.  This is the same as the 

C:\WINDOWS folder you see in explorer.

The Recovery Console allows basic file commands like: copy, rename, replace, delete, cd, chkdsk, fixboot, fixmbr, etc.

For a list of Recovery Console commands, enter help at the prompt or read about the XP Recovery Console here:

http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/recovery_console_cmds.mspx?mfr=true

A good idea before starting things is to first verify the integrity of your file system using the chkdsk command.

From the command prompt window run the chkdsk command on the drive where Windows is installed to try to repair any problems on the afflicted drive.

Running chkdsk is fine even if it doesn't find any problems.  It will not hurt anything to run it.

Assuming your boot drive is C, run the following command:

chkdsk C: /r

Let chkdsk finish and correct any problems it might find.  

It may take a long time for chkdsk to complete or it may appear to be 'stuck'.  Be patient.  If the HDD light is still flashing, chkdsk is doing something.  Keep an eye on the percentage amount to be sure it is still making progress.  It may even appear to go backwards sometimes.

You should run chkdsk /r again until it finds no errors to correct.

Remove the CD and type 'exit' to leave the RC and restart the computer.

You do not have to adjust the BIOS again to boot on the HDD since the CD will not be present.

I have an PH Pentium 4 running widows xp. I am trying to repair my system. I'm past my last point and
I got my computer to boot from the cd. Now I'm trying to us the Recovery Console but I'm now asked
for the Administrator password. I have tried leaving blank and lots of passwords which I use but none worked.

Is there a way around this? If I can passed this problem I think I can get it fixed.

What version of XP are you running (Home, Pro, MCE)?

You can fix it, but if I tell you how, I will violate the Terms of Use of the forums regarding circumventing security.  They have already banned me once and I am not through having fun with the Microsoft engaged Support Engineer "experts" yet so don't want to take any chances right now.

However, you might have luck finding ideas by using a search engine (Google) regarding a lost or missing XP Administrator password.
