amp I can boot into my bios just fine by spam pressing a certain key which I have now forgot plus I have also found an alternative way to boot into my usb and that is to go into that windows recovery mode thing that gives you all of these different tools to help with computer troubleshooting and one of the options lets you boot into a usb.
Anyways in case you still need it my computer model is an Acer Aspire V Nitro (VN7-571G-746D)
I also see a model number under the dc rating thing but I am a bit sceptical because I’m not sure if I’m supposed to leak that
amp you actually don’t have to pay a subscription to keep getting security updates for Windows 10, you get one extra year by spending a one time fee of 30 dollars or just 1000 Microsoft points, or completely free if you sync your settings with OneDrive (or at least that’s what I’ve heard, so what I said may not be true)
