| A. | It will install if it detects XP, so you do NOT want to empty the drive. However the install will wipe your drive - you do NOT do the uninstall of XP, you let the installer do it. If you want to preserve your installed appliication programs such as Office etc., the installer will do it provided that you give it an empty external hard drive of sufficient size. The installer will move everything to the external hard drive, then wipe the primary drive, install Windows 7, and then move stuff in from the external hard drive.
I do not know if it will use an empty internal hard drive for the migration.
I have not done this process but know several who have. They said that for a large system (i.e. 100GB of protrams/data) it could take the better part of a day to do the processing. |
