Where does the OS reside after an upgrade installation ?
This is just something I wondered over.
For example... if you take a traditional HDD and install Windows then I believe the OS will reside in a contiguous portion of the drive. So if you had Windows installed on a 100Gb partition and the OS took 20Gb, then the first 20Gb are 'taken'. You then install your own programs and user files, so lets say the first 30 or 40Gb are now taken.
Assuming I'm correct so far, what happens when you upgrade Windows ?
Does the original OS get replaced in full and so still reside in that first 20Gb or so ? (give or take of course, if the new one is smaller or larger then there will be gaps or it will move further on).
After the upgrade we have a 'windows.old' folder that contains the old OS in case we need to go back.
Where does that now live ? Is it the old 'first 20Gb' still in its original location and bundled up to delete, or has it been moved to the next chunk of free space ?
Hope that makes sense and isn't to daft a question. I just wondered ultimately where the 'new upgraded OS' lives i.e. is it now still at the start of the original partition having replaced/overwritten the old OS, or is 'windows.old' still living there with the new OS elsewhere on the disk.
