In my case, where I had my computer’s file system corrupted, I was using Windows XP installed to a FAT32 partition.
You can solve problems in Windows XP file system by using the program CHKDSK that comes with Windows XP itself. To do so, use the following steps:
Boot the computer using the CD-ROM drive with the Windows XP installation CD.
When the Welcome to the Installation Program screen appears, press the R key to select the repair option.
Type the admin password (in case the partition is NTFS) and press Enter.
In the command prompt type chkdsk /r and press Enter. This command will locate damaged sectors and will try to recover data.
Next, type the chkdsk command again, now with the /p option (chkdsk /p). This command will verify the disk media status.
At last, type the fixboot command to correct problems in the partition table.
Type exit to restart the computer.
By using the procedure described above, I solved the problem in my computer’s file system. You can also use the Norton Disk Doctor utility from Norton Utilities pack to solve problems in your hard disk.
