missing operating system : donot have original CDROM/disk for windows 2000 professional

Dear Sir/Madam : I have IBM laptop with Windows 2000 professional installed. REcently i installed Service pack 4 to update my computer. It gave some problems so i unistalled the service pack. As I restarted my computer it gave an error on boot up saying some windows startup file missing and wouldnt bootup. AS this laptop was imaged at work where i no longer work so i don't have the original CD's/disk or windows 2000 software that was installed on the laptop. I used my home desktop Win 98 recover CD to boot the laptop up and  answered  yes to first few prompts about FSdisk missing etc. Now it says Missing operating sytem. I got  Win XP pro.iso.exe cd from a friend but laptop doesn't execute it. my guess is Win xp pro.iso.exe is not a  bootable CD? I dont have floppy drive on this laptop just the CDROM. So the bootable disk as available to download on microsoft website wouldnt be useful for me. IS there a bootable CDROM that i can download that would solve my problem? what solutions you mite suggest? VIshal

no... you need to use a burning software to burn a cd.. when you open what software your going to use you want to select make a data cd... then when you get to the browser window of your burning software you want to look for a menu option that says something "Burn cd from image.." "Make cd from iso.." and so forth... once you create the cd from the iso it should be bootable...

I have ADaptec Cd burner software installed on my computer. When i open it up to burn a CD. It doesn't have an option or asks me  for an option which says MAke CD from ISO or burn cd from image. I can think of couple of reasons why this happening. 1. the win xp pro.iso.exe IS this is correct format of the file? i mean does the iso files has .exe at the end of it ? Secondly that my cd burner software doesnt supports converting from iso image to cd image. In that case i can download a burning software from download.com dat would support it. But i am not sure if that is what i need to do. Suggestions please? BTW going back to my original question. Is this the only way to restore my computer? i.e to install a new OS/boot from the win xp pro.iso.exe cdrom (after making cd from it) ?

Adaptec cd burner may not support it... can't remember... you can download and iso burner from download.com... and no pro.iso.exe wouldn't be the correct extension... maybe it's a self extracting zip file?... and yes... this would be the only way to get your computer back up unless you have another operating system disk...

Okie so i extracted the Win pro.iso.exe file to a folder. now it came up with a folder which contains I386 folder Autorun,license,readme,SETUP,win51, win51ip files. When I click the SETUP icon. it opens up a wizard. Which says Welcome to WIndows XP. WHat do you want to do now? 1? Install windows XP 2) check system compatability. SO looks like it would install windows xp if i went through with the setup.

Well I am not sure what to do next. DO i take this new folder that was extacted from win pro.iso.exe file i.e the windows XP Proffessional folder which contains  I386 folder Autorun,license,readme,SETUP,win51, win51ip files. Burn it on a CD and try to start my laptop with this CD rom? Is this a bootable CD? or do it need to do something else to fix the missing operating system error.

ok.. what you had wasn't actually an iso of the windows xp cd... it was just a zip file of all the files on the windows xp disk... unfortunately you will only be able to use that if you already have a windows operating system already running on the laptop...

-I would burn you extracted  I386 folder Autorun,license,readme,SETUP,win51, win51ip files to a CD-Rom.
-Then I would boot useing you windows 98 CD.
-On boot-up i would tap the F8 key untill the advance boot options appear.
-Select The Command Promt Option.
-Then Swap out that cd with you Burned XP CD.
-cd to the I386 Folder
-Type intall or setup to luanch the install prosses.

Thanks for your help so far. THings are looking good. Now i am able to start the setup for windows xp pro with the cd room. One point of the setup. It asks to select the partition where i want to install the win xp OS. In my partitions, there is only one choice
C: partition1 [NTFS]. There are no other partition or partitioned spaces. If i select this partition which i have as i have no other choice. It says "you chose to install win xp on a partition that contains another operation system, (which is correct. I had windows 2000 pro installed on it originally). And reccomends to create seperate partition to install the win xp pro and use mutliboot install.

Now how do i create a seperate partion for ex D: or something. As without this CDROM i dont have access to anything else. As it said operating system missing earliar. Any suggestions?

I went ahead started the installation of WIN xp pro on the single partition C: [NTFS]
After the setup copied the files and rebooted the computer. It tried to start the computer from the hard drive. But gave the following error and keeps rebooting.

invalid boot.ini file
booting from c:\windows\
ntdetect failed

Any suggestions on how can i fix this problem?

You are getting this error because the installation did not complete successfully.

-When you are at the screen asking about the partitions.
-I would delete the partition (there should be an option at the bottom of the screen)
-I would re-run the setup program if setup shows no partition created.
-Create a partition and then finish the install ...
NOTE: if the partition still exists after reboot delete it again.

Okie i will delete the partition and start again. Also on the underneath suggestion. I tried tthis. I pressed F8 and it took me to advanced option where i replace the CD and pressed commnad prompt. SO now it took me to the command prompt of the win xp pr.exe cdrom which has the setup file. If i insert thiis CDROM at my home computer it opens up as windows setup. So i know its working. But on the laptop at the command prompt it wouldn't accept any command. It says pleasee specify the command utility you want to use such as c:\windows\command.com.

MY guess is that my CDROM doesn't have the command.com file for me to execute install or setup command. Any suggesttions on how can i get around this? so i dont have to go through the whole setup manually

SEcondly when i run the WIn xp pr setup. It brings me to the screen where it says do you want to installs windows setup files. or press R for repairing the windows installation.
And if i presses it takes me to the C:\windows of the laptop where i can have access to all the files. I can see the boo.ini file ntldr and ntdetect.com files.. I thought i would mention this .. In case i use this to my advantage.

-I would burn you extracted  I386 folder Autorun,license,readme,SETUP,win51, win51ip files to a CD-Rom.
-Then I would boot useing you windows 98 CD.
-On boot-up i would tap the F8 key untill the advance boot options appear.

-Then Swap out that cd with you Burned XP CD.
-cd to the I386 Folder
-Type intall or setup to luanch the install prosses.

Nightmare continues. After the installion was complete. Laptop rebooted Now it brings up the microsoft windows XP proffesioanl startup screen and then immediately reboots. ANd keeps doing that. My guess is I should do the whole setup again? Seems like the Windowws XP Proffesional CD i have is corrupted. BUt this is the only thing i have to work with.

Out of curiosity, did you set an active partition?
i.e.
-Then I would boot useing you windows 98 CD.
-On boot-up i would tap the F8 key untill the advance boot options appear.
-Select The Command Promt Option.
-type fdisk /mbr
-type fdisk
and use the menus to see if the partition you want is the active partition

Okie i just check. The only partition where WIndows xp is installed c:\windows is aCTIVe.

I also booted the laptop from CD rom and did a repair (after pressing the F8 button, so the second R not the first)  on the drive where OS is installed. Went through the whole procedure but same result. LAptop keeps rebooting after first start up screen

I am going to do a clean install again. Please advise otherwise, Suggestions on why this is happening?

visualcoatCommented:
This happened becuase of a currupt Update
you will need to deleted the partition and perform the whole prosses again.
this time when updating do less updates at  one time. Reboot often after updates.

okie finally i am up and running. Thank you all for your support and patience.

Finally i had to burn a new CD. Cuz the CD got corrupted after constant re-installation. And after deleteing the partition and formating to start a new install with a new CD. It all went smooth.
