So I split the HD in two units and I tried to make boot from a USB for install windows 7 in that second unit but even changing the order in the Bios it don't recognize the USB like bootable. I tried with Rufus also and nothing.
One time i make it I see there is no support from Acer to this laptop drivers in windows 7, how could I find some compatible ones?
And I would like to keep the other half of the HD with Windows 10, but I would reinstall from 0 to have it clean without those applications what it comes preinstalled on the system and also for have it in Spanish. But I don't see where is my license number of Windows 10 (it didn't came any sticker with it), can I find it some way to reinstall windows 10 from 0? Or just putting again my email and password it will recognize i have Windows 10 license in this laptop?
Thanks for the answers!
