Hello everyone,
I have an Acer ES1-533-C39G and I want to install Windows 7 but there is no way to change it from UEFI to legacy mode because the option is grayed in the bios. I made a usb stick using rufus with gpt partition scheme for uefi (non cms) system but every time I get "no bootable disk" message.
So, I need help to get an unlocked bios for this model.
Thank you.
P.S: I attach screenshots for the configuration I tried in the bios tabs and a screenshot of the configuration of rufus using the lateset image of W7 by teamos.
