i installed xp on my comp and realized that my hard drive was now labelled a the e drive, i have 2 cd roms and a 250mb zip drive, how can i change the e back to c to make everything work normal again, thanks

You can change things around, but be careful that applications and directories are where they were installed. No use renaming the C Drive to D Drive if application were installed in C:\Application etc. If you do manage to mess up your applications, use something like Norton System Works to fix up registry if everything gets messed up. Failing that use DIsk Manager. To open Computer Management, click Start, and then click Control Panel. Click Performance and Maintenance, click Administrative Tools, and then double-click Computer Management. You must be logged on as a computer administrator in order to complete this procedure. A computer can use up to 26 drive letters. Drive letters A and B are reserved for floppy disk drives, but you can assign these letters to removable drives if the computer does not have a floppy disk drive. Hard disk drives in the computer receive letters C through Z, while mapped network drives are assigned drive letters in reverse order (Z through B). You cannot change the drive letter of the system volume or boot volume. An error message may appear when you attempt to assign a letter to a volume, CD-ROM drive, or other removable media device, possibly because it is in use by a program in the system. If this happens, close the program accessing the volume or drive, and then click the Change Drive Letter and Paths command again. Windows 2000 and Windows XP allow the static assignment of drive letters on volumes, partitions, and CD-ROM drives. This means that you permanently assign a drive letter to a specific partition, volume, or CD-ROM drive. When you add a new hard disk to an existing computer system, it will not affect statically assigned drive letters. You can also mount a local drive at an empty folder on an NTFS volume using a drive path instead of a drive letter.
