Repairing Windows with different version of Windows !!

Hi all
This seems to work just in case you are testing various versions of Windows and have problems with Booting

You CAN use the repair option on a different level of Windows to the one you are currently using -- so long as both the install disk and the target Windows system are both x-86 or x-64.

I've repaired a W7 Ultimate install with the repair option booting from a W7 Home Premium disk and also the other way around

You don't need (for the repair function) to enter a serial number.

Note that you should only use this for BOOT problems and only if you don't have the correct disk immediately to hand --saves downloading a 4 GB or so ISO --even using a FAST connection it will take a while.

For System Recovery Options like Startup Repair, yes.

But not for the upgrade-over-itself Repair Install which needs the full same-version installer with SP1 if you have it.

The two Repairs are constantly confused here.

Thanks, Jimbo.
