Reading your (Greg...) reply and links I'm really starting to get a lot more comfortable. However, I've got a lot of questions. Too many for one message so I'll ask a few, get a reply and ask a few more (if you(all) don't mind).
Regarding the clean install of the 64 bit OS on media. ImageBurn-->CD okay. As for the stick:
1. Is there a preferential reason to use the stick to boot install the ISO file vs a CD?
It can be faster. A CD won't work since Win7 installer uses a DVD.
2. The link says to format the stick FAT32 to insure a clean install. Why would the format type matter?
Regarding the 64 bit ISO file:
1. Using the ei.cfg removal tool...If I understand this correctly, If I run the tool against the install file (X15-65733.iso) I would then have my choice of not just the Home Premium but any of the flavors of Win7?
Only necessary if the ISO is not for your licensed version, which is the only one the key will work for.
2. [CRITICAL]The following text from one of the links says: "You just need let the installer know which edition matches your product key (Note: Your disc still needs to be the same kernel as your key (i.e. 32 or 64-bit)" which says to me MY key is specific to my 32 bit and that a different key would be required for the 64 bit file referenced above?
The installer ISO needs to be 32- or 64-bit specific, the key can be used for either but not both at the same time.
