2, If you are unable to load Windows. Then you should try to access your ntfs partitions by making a ntfs boot disk with NTFS4DOS (freeware). You can download it from http://www.geekswhoknow.com/files/ntfsinst.exe You will need a floppy disk.
After you load the bootable floppy disk onto your damaged system, select either option one (1) or option three (3). If you selected option one (1), type chkdsk /r at the command prompt, and your problem should go away after the disk has been repaired.
Note! Unfortunately there is a chance that your partition is corrupt beyond repair and all of your data is lost. In that case, you need to reformat the partition to be able to use it again.
