In Reply to: What version of Dos do I have? posted by steve on November 21, 2007 at 17:56:47:
Windows XP contains a copy of the core MS-DOS 8 files from Windows Millennium, accessible only by formatting a floppy as an "MS-DOS startup disk". Attempting to run COMMAND.COM from such a disk under the NTVDM results in the message "Incorrect MS-DOS version".
Unfortunately you do NOT have a version of MS-Dos with XP. Read what's displayed when you enter Ver, it probably shows Microsoft Windows XP [Version 5.1.2006] so refers to the Windows version not Dos. Undelete is not supported in Command.com or Cmd.exe in NT.
Here are the supported commands http://www.ss64.com/nt/ or http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/ntcmds_o.mspx?mfr=true
Good luck
