Have an Aspires ES1-331 and was trying to install Windows 10 but the SSD partition didn't have enough space. I stupidly deleted the recovery partition thinking it was going to be okay, but now it won't boot into Windows.
I created a Windows 8.1 recovery media onto a USB and since these new laptops don't have COA, I did the whole no product key thing. I tried to repair the existing Windows 8.1 partition but since the 9GB in the recovery partition has been deleted and is unallocated, the installation program couldn't repair it. I ended up just installing a new copy of Windows.
My question is, how am I able to activate/authenticate Windows at this point? I can now log into Windows and can go online but I'm I don't have a product key and I'm not sure if Acer Recovery will help. I just want to put things back to factory default, given that I've deleted the recovery partition and the SSD is all 1 main partition now (there's a couple of other small partition that are like 100mb each but I left those alone).
