installing Windows 7 x64 on a partition RRS feed

  • Question

  • I currently have my hard disk partioned into two drives. Drive C contains Windows XP (x32) and all my files. Drive D is formatted but otherwise empty. Can I install Windows 7 (x64) in my D drive and creating a dual boot? Reading some of the other posts it looks like it does not like doing this. Since the product key is one time use I don't want to waste it if it doesn't work.

    Many thanks in advance

    Having said all that, it will work but booting into XP will be destructive to Windows 7 VSS files (Backups, Previous Versions of files, System Restore points, and many others).  Vista and Windows 7 volume shadowcopy service files are incompatible with the XP version of volsnap.sys, the VSS driver.  XP's volsnap.sys scans all volumes visible to it as part of XP startup and deletes all incompatible VSS files it finds to protect the user from potentially restoring data from corrupted files.  Because of differences in file formats, XP volsnap.sys does not recognize Vista and Windows 7 VSS files as valid.

    The resolution is to hide Vista and Windows 7 volumes from XP by means of a registry key.  See
