I have 2 Computers modified with Bios Mood to Dell and a Asus brand. I have the win10 upgrade showing in my desktop bar. I would like to installwin 10 when it will be on market or when I can downloaded, following the upgrading method from Microsoft. But at the same time I want to install from zero, not to do a upgrade over win7. Will it be possible to do it?. I mean I havent a license number just the one which came with the license from the programs to install it from here, when you modify the bios you have to insert the brand license...... So Ifd I format the hard disk Microsoft will give us a license key with the ISO or image previously downloaded.? Thankl you in advance and sorry for my english.
