After installing Windows my default drive is not C:

To change the location of your Windows installation, we recommend reinstalling Windows from scratch. Attempting to hack the registry or change other system settings to fix this issue often causes more issues than it fixes.
Will Windows install to the C: drive the next time?
Yes. Because the hard drive is detected it will be set up as the first available drive when booting from the Windows XP disc. When reinstalling Windows, we suggest you follow the steps for reinstalling Windows XP.
Can I run Windows from a different drive letter?
Yes. There will be no issues with running Windows from a different drive letter. However, many programs default the installation path to the C: drive. However, if you use a different drive letter, you'll have to specify that drive each time you install a program, which can be annoying.
