ntoskrnl.exe missing at bootup

By chaos buddha ·
I had the following config of OS on my PC:
C: Win XP sp2 (root)
XP 64bit 2003 edition
E: longhorn on my PC.
C: accidently got formatted & xpsp2 reinstalled: I edited the new MBR to show the other distros...When I try to load the other OSs via OS select menu at boot,I get the message "ntoskrnl.exe missing:reinstall a copy of it".So I did a copy-paste from the windows installation CD to whatever folders of the other OSs that were analogous folders to those in XPsp2.But that didn't help.When I try to repair the distros via the intallation CDs,I end up working in Caldera OS that I'm not familiar with.Plz help me out without having to format it again.Also how do we "uninstall" an OS??I mean without having to format the drive....

You remove an OS by removing the partition on the drive on which it is located with FDISK or some other utility.

How much of the hard disk did you accidentally format?

Unfortunately here it's not just a missing file but a file compiled for your particular installation so just cut & pasting will not cure the problem.

From your description you had XP loaded First and then added the other Versions of Windows which would have created a Boot Loader for each individual install of Windows with the correct sub routines to get the different OS to load. This is what is now missing and you can either edit to create the correct parameters or better still install another Boot Loader that will be easier to configure to run each OS by itself and make it possible to Multi Boot without invoking any of the other versions of Windows when one starts loading.

As you are using a Windows Only setup the best option would be to install something like System Commander on the XP Pro installation and then setup the Boot Loader that comes with it to boot the other OS's.
