Hey there,
i've a feeling i'm in a fair bit o' trouble here so any help or ideas are welcome....

I left my pc defragging last night only to come back to it later and found it had restarted with the words "Mising Operating System". It scans for boot record from the floppy then IDE 0 and says "OK", then it comes up with the "Missing Operating System" line.

My Drive is all 1 partition by the way, laziness stopped me from getting around to changing that.

Has anyone else been in this situaion and got it sorted out???

Please help me!!!!

By the way i'm using Win 2000 Pro and don't have an emergency repair disk....

If your luky...putting restore disk in....close it and starting comp will get that to boot to re-install. open your case and see if anything is still melting. Wait for someone who knows more than me to really do anything though. sounds like your comp is really jacked up :thumbsup: :flowers: -joe

Err I forgot about that My mistake

There is 1 of many ways this could be happening did you remove the Floppy Disk from the drive when you booted it up?

If so Try this Insert the Floppy again and at the A Prompt again type sys c: press enter

you should get a System Transfered message remove floppy again and reboot
Again let us know any Error's / Progress that has happened!

BTW That is a Semi good Sign.

You have the 2K CD?

I must have misread your post my mistake. (again)

Insert the CD Boot with the CD start the "Setup" Press "R" to Repair a Windows 2000 Installation. then Press “C” to repair a Windows 2000 Installation using the Recovery Console. Next screen will list and ask you which installation you would like to login to. Then it ask you for the Administrator Password. Now you’ll be a Prompt C:\Winnt> type “fixboot” after this type “fixmbr” now type “exit” and reboot. this should fix the problem and if not I have one more idea.
Again let us know any Error's / Progress that has happened!

P.S. You tried copying the NTLDR and NTDETECT.COM this is part of my next Idea how did you go about doing it?

Cheers for all the ideas by the way...

Have been in Recovery Console and tryed Fixboot & Fixmbr but no joy, then, still in Recovery console i tryed to copy Ntldr & Ntdetect, still no joy, then booted up with 98 floppy disc and tryed to copy across Ntldr & Ntdetect again but still no luck...

At this stage i've installed Win2000 on a spare drive so will probably recover the fiiles onto the new disc this evening but i'm still gonna tinker around with the crashed drive to see if i can get it up and running again so any suggestions are still much appreciated...

I'm not ready to give in just yet....

When in Recovery Console did you by chance do a Directory Listing to see if you can see the contents in your C Drive (You will only be able to be in Root Directory)

Edit: LoLucky not useing Brain you would have to have an Installation to get into Recovery Console

NOTE: Have you check the Contents of you Boot.ini file? that could be what is corrupt!

i think you can have a Boot.ini running from a Floppy if you have a copy of NTLDR and NTDETECT.com on that floppy (don't Quote me on it, I just read someone but have never tried it out)
