USAFRet :
You can't use the same license for two installs. What exactly do you mean by 'multi bootable' ?
Dual booting - so I get an option on startup asking me if I want to use the backup copy:
Windows Boot Manager
--------------------
identifier {bootmgr}
device partition=C
description Windows Boot Manager
Windows Boot Loader
-------------------
identifier {current}
device partition=C
path Windowssystem32winload.exe
description Windows 7
Windows Boot Loader
-------------------
identifier {current}
device partition=D
path Windowssystem32winload.exe
description Windows 7 (backup)
-----------------------------------
As for the license, surely it pertains to my mobo? Wouldn't it be the same as reinstalling Windows?
I'm gonna try following
this article and using disk management to copy the partition.
