do a repair of your operating system.  boot from the cd w/ the windows cd inside to repair the system and not to install the whole system.

Is the drive you are trying to format still the 'boot' disk?\n\nYou need to be booting on the new drive before you can format the 'old' disc.\n\n///

As already suggested, the hard drive is a likely candidate.  If you have Windows XP installed, try booting from your windows installation disk.  (You may have to change your BIOS settings so tha the CD drive is first in the boot sequence and the hard drive is second.)  When the setup screen displays, choose the Repair option.  This will take you to the Recovery Console.  Then run "CHKDSK c:" and see if reports errors.  If it does, you may be able to repair it using "CHKDSK c: /r".   You could also try the diagnosic program that came with your hard drive (or can be found on the manufacturers site).\n-------------------------\nDid you try the "repair" option on the installation screen (I think "R" instead of "enter") and then CHKDSK as described above?

When you get a STOP error message like this its almost certainly a device driver problem or related to a device driver which your system cannot load at start up.\n\nThe problem is that STOP errors like this are BAD news because the operating system has a MAJOR problem or could even be damaged, i.e. missing files. There are two or three approaches you can try inorder to resolve this (the easiest first hardest last).\n\n1) You can reboot the machine & key F8 at start up just after the windows logo shows. This gives you a menu, from the menu choose the "last known good" option and key return/enter and the machine will attempt to load a stable system. If that works fine and good. (this option uses a saved undamaged copy of the windows registry).\n\n2) You could run a boot logging process to help you find the specific device driver which is causing the OS to bork. Again reboot and key F8 but this time, see the option which offers boot logging. This helps by creating a log file that usually shows which files are causing the problem or are missing.\n\n3) Restore from backups you have (NOT the OS system restore feature, or roll the system back) I'm talking proper previously made backups made precifically for restoration if you have made them.\n\n4) Re-install the whole of windows, your Apps, drivers and data (the whole shooting match!). Windows might allow you to run a repair and that might also be an option which could work.\n\nBest of luck with that, IR

Assuming (isn't stated, so I'll go for most popular) you are using win XP, insert the installation disk and then boot. Then access the recovery console (see sources for a how-to). Then run fixmbr (command line interface, so type and hit enter). This repairs the part of the disk that contains the information on where Operating systems can be found on the disk, this may help!\n\nAdditional note: maybe read the warnings first - if you have a dual or multiple boot systems (more than one OS) or a non default bootloader, this may cause problems. If you have no clue what I'm on about, then you probably don't have either.

Make sure there are no floppies or cds in the computer when it is booting up.  Otherwise your hard drive may be in trouble.

Try checking the disk for errors with the repair option set.\n\nWindows is not able to check for errors on a removeable disk at boot time. You need to make sure that no programs are running from the disk or have files open on that disk.\nYou should disconnect the disk, restart windows in safe mode, reconnect the disk and then check it for errors while in safe mode.

If the boot disk doesn't work, put back in your operating system setup disk, and follow instructions to upgrade without erasing your hard drive.  If that doesn't work, call the manufacturer.\n\nYou can usually download and create a boot disk from the internet if you don't have a boot disk.

You might want to think about reformatting your hard drive and doing a fresh install of the operating system. This is usually a last resort after all other troubleshooting is done. If the install does not work then you might be looking at a hardware problem.

u have changed the boot priority to cd so tht the system always boots frm cd. once it has completed the "copying files" process and restarts, goto bios and change the boot disk proirity to hard disk. this will probably solve ur probm.

You are at the command line prompt which allows you to enter DOS like commands to fix your system.  I suggest you read up on the available commands (such as fixboot and chkdsk) before you do anything as there are a number of options but you really should understand what needs to be done before you use the command line to repair your system.

Additional information about doing this can be found on document CH000626. \n\nCorrupt boot.ini file\n\n    This issue is often caused when the boot.ini is missing or improperly configured. This issue often arises after a user has recently added or removed an operating system on the computer or added or removed hard disk drives in the computer.\n\n    Make sure the line pointing to the operating system and it's drive and partition is properly configured in the [boot loader] and [operating systems] section. Additional information about boot.ini can be found on document CH000492. \n\nMissing boot.ini file\n\n    Microsoft Windows XP users:\n\n    If the boot.ini is severely corrupted or missing a user running Microsoft Windows XP can rebuild the boot.ini to resolve this issue.

In the setup menu, type R to start the repair.\n       3. When prompted for the ERD diskette insert the diskette and inspect the startup environment.\n\nMissing or corrupt ntoskrnl.exe file\n\n    If the ntoskrnl.exe file is corrupt or missing this can also generate the error. To restore this file follow the below steps.\n\n       1. Insert the Microsoft Windows XP CD. Note: If you have a recovery CD or a restore CD and not a Microsoft Windows XP CD it is likely the below steps will not resolve your issue.\n       2. Reboot the computer, as the computer is starting you should see a message to press any key to boot from the CD. When you see this message press any key.\n       3. In the Microsoft Windows XP setup menu press the R key to enter the recovery console.\n       4. Select the operating system you wish to fix, and then enter the administrator password.\n       5. Type expand d:&#92;i386&#92;ntoskrnl.ex_ c:&#92;windows&#92;system32\n       6. You will then be prompted if you wish to overwrite the file type Y and press enter to overwrite the file.\n       7. Type exit to reboot the computer.\n\nWindows NT installed on a partition bigger then 7.8GB\n\n    If you are running Microsoft windows NT 4.0 on a partition larger than 7.8GB this issue can occur if the boot files are located outside this limitation.

your boot.ini was messed up when you reinstalled, the original copy is more then likely gone. To correct this problem so it doesnt prompt you any more, follow these instructions, right click my computer and goto properties, click on the advanced tab, under startup and recovery, click settings, under system startup click the edit button. the last two lines displayed on this window are the two options that are given to you at boot. they are in the same order as displayed on the boot menu, so before you delete the line make sure you know which one is working and then delete the one that isnt. if prompted to save when you exit out do it. restart your computer and presto, problem solved.
