What about clean install and quick install option, and does it even matter.
I have never heard of a quick install option. The only ways to install for the average user (without getting into RIS, Sysprep or any of the other corporate type installs) are a clean install in which you boot off of the CD and wipe everything out and install over it, or an upgrade in which you put your CD in the drive while running under your old OS and it will walk you through the process.
Thinking about it, what you might be confusing is the two types of format options that you can choose when you install your OS. There is a quick format which simply rewrites some of the MFT infromation and then starts the install, and there is the normal which completely formats the drive and then proceeds to load the OS. The quick format is faster, especially as the size of your hard drive that you have to format increases. The more disk you have, the longer it takes.
A quick install is basically an upgrade and is overlayed on your existing OS. This means you are stuck with fat32( if thats what you have) and cannot change to NTSF which does not allow for some of the security features. You cannot add any partitions and some customizable options are locked. It does allow you to keep your files.
Not entirely true. You can always convert a drive using the convert command. Something like this
convert c: /fs:ntfs
from a command prompt.
The OEM version does not allow for the quick install option which would only be useful if you were doing a full install on a new system and an upgrade on another or simply an upgrade on one computer in which case you would buy the cheaper upgrade rather than the full retail version that allows both.
I wonder about that. Try running the WINNT32 in the D:\i386 folder (replace D with your drive letter of course) from your currently installed OS. I haven't ever tried it, but I would bet that you would get the standard upgrade screen.
