Open a cmd prompt in Administrator mode
Type:
bcdedit
//Save a copy just in case
bcdedit /export C:\SAVEDBCD
//To restore
bcdedit /import c:\savedbcd
bcdedit /set {current} description "My edited Windows Boot Entry"
NOTE: This changes the title of the boot menu entry "{current}".
bcdedit /set {ntldr} device partition=E:
NOTE: This tells bcd that Windows XP partition is drive E:
bcdedit /set {ntldr} path \ntldr
NOTE: This tells bcd that the ntldr file which is the winxp bootloader is on root folder "\" (of drive e: as stated above)
bcdedit /displayorder {ntldr} /addfirst
NOTE: This places Windows XP as the first OS on the menu list.
bcdedit /default {ntldr}
NOTE: This places Windows XP as the default OS to boot first with.
bcdedit /displayorder {33342343-3424-2342342342-2344} /addlast
NOTE: This tells bcd that the boot entry with UUID 3334... should be the last entry on the menu.
You can copy your existing VISTA or Windows 7 boot entry to another identical. Then you can change settings on the new entry to experiment. You will always have the first entry available, so it's safe to play with.
bcdedit /copy {current} /d "New Windows 7 boot entry I just copied!"
this will give you a line:
NOTE: The entry was successfully copied to {4c21825f-e04b-11dd-b760-00195b61617a}. The {4c21825f-e04b-11dd-b760-00195b61617a} is the UUID of the new entry that the system just created. Yours will be different than mine! This is its identifier and you should use this to address that entry. Example:
bcdedit /set {4c21825f-e04b-11dd-b760-00195b61617a} numpoc 2
NOTE: This adds the 2 CPU Core support during boot, like you do in msconfig.
bcdedit /deletevalue {4c21825f-e04b-11dd-b760-00195b61617a} numproc
NOTE: This deletes the numproc parameter from entry {4c21825f....}
bcdedit /delete {4c21825f-e04b-11dd-b760-00195b61617a}
NOTE: This deletes the boot entry {4c21825f....} completely. In order to delete an {ntldr} entry, you must use the /f switch to force deletion: bcdedit /delete {ntldr} /f
