Hi, I'm trying to reinstall windows on Acer Aspire ES1-533 and I can't boot to usb, because UEFI boot mode is selected and I can't swap it to Legacy, as Boot Mode option is just greyed out. I've tried checking some information on the internet, it suggested to set a supervisor password, did that, saved and exit, restarted to bios again and now only Secure Boot is not greyed out (it was before), but the Boot Mode is still greyed out. Tried swapping values of Secure Boot to both enabled/disabled and restarting the PC to get to BIOS again, but the Boot Mode is still greyed out. I'm really puzzled of what to do to be able to swap to Legacy mode.
