I have been at this since yesterday evening.
I have tried downloading the 32 and 64 bit versions. I get the same error no matter which I try.
I get "The boot image could not be authenticated"
I have disabled secure boot and enabled legacy boot.
My only guess is that I am doing something wrong in burning the ISO to dvd. I use WinIso free. I created many bootable discs before and never had this error.
I am installing Oracles VM now to see if that can get me running for now.
my hardware is
Windows home 10 64bit
Processor: AMD e1-2100 dual core with built in radeon graphics
ram: 4 gb
