So my brother asked me to format his laptop's HDD (intel i7 4th gen, acer aspire V, WD blue 1TB HDD), so i did that, and then he asked me to install an OS (he was using windows 8 and wanted win10). So i tried installing windows 10 by using a usb boot drive key i created with microsoft's official software, but after installing, the laptop reboots and it takes me all the way back to the first installation screen. Then y tried rebooting and unplugging the boot key while the laptop reboots, i was able to register a name, email adress and time zone in windows 10, but then before i got to windows desktop the computer froze, and it kept freezing every time i rebooted. I tried getting the OS ready to use by removing the HDD and plugging it into my dektop, and it went perfectly, but when i reinstalled the HDD in the laptop it still froze when booting. Then i tried installing windows 7 ultimate using a usb key i created with rufus and a sketchy windows 7 ISO i found on a random page (scanned it with norton 360 tho), and it went right, so i can go to windows desktop, but now the laptop doesn't seem to be able to search for (and less to connect to) wifi signals. I'm tired of trying to fix this by myself, please help
I will proceed to try another windows 7 ISO and then if that doesn't work either, i'll try with windows 8, but any help is welcome. Thanks for reading.
