If Win Vista is under the chaos, how to do

drive letter confusion is Microsoft's old problem. Microsoft's Windows installation CD has always been in its own program to confirm the drive letter of the hard disk partition, but this time Vista is more aggressive. When booting from the CD, the drive letter of the partition to which it is installed is forcibly changed to C. The following other drive letters are also arranged according to the previous Microsoft Windows installation conventions.
Vista drive letter is confusing, so I have to adjust it and install it again. The method is to restore the wrong drive letter to the previous look in Vista. For example, in the previous case, it should be restored to: C: -> Z: -> F: , D: -> C: , Then restart Vista, of course, when the drive is restored, it will prompt a lot of errors, and neither Explorer nor Computer can browse. At this time, you can only use the "Win+ R” shortcut to start the “Run” box to confirm that the drive letter has been restored to the original normal state. Then directly type Setup.exe under your Vista installation CD (or Vista installation ISO virtual drive). For example, your CD-ROM drive letter is X:, put the installation CD into it. Enter X:Setup.exe in the Run to run the Vista installation. This way, when the drive is upgraded or the new custom installation is performed directly, the drive letter is normal, and the installation program in the installation CD will not recognize and arbitrarily make claims. Of course, if some hardware is not standard and incompatible, it may not be upgraded. Then the new installation, the old Vista will be automatically backed up to a Windows.old directory by the installer. Just you must install it under this existing Vista, otherwise you will start the installation from the CD-ROM drive, the drive letter will still be confused. Because the drive letter in your existing Vista has been adjusted, the installer will refer to the original correct drive letter when doing an upgrade or a new installation under it. However, it is annoying enough. Even if the installation is done twice, the drive letter is correct, but the identification of the partition letter on the installation CD is still a big problem.
For example, if your system is broken, you need to use Vista's installation CD to repair it. Vista installation CD will still be very good at discriminating the drive letter when you perform System Recovery, just follow the drive letter when you boot from the CD. Disorder is a truth.
