When XP was retired, my old 32 bit laptop couldn't run the 64 bit Windows 8, so I installed Ubuntu. But Ubuntu is heavy and ran real slow. So I tried Puppy, and it brought new life to the old machine. Faster than anything I've had on it. So I thought I'd try it on my Gateway. Well, I can't get it to run from DVD or Flash Drive. So I read about getting around the UEFI. So I follow the procedure, but it just takes me into the old BIOS and those settings don't help. I've tried disabling Secured Boot and everything else, but no go. I've read a little about how some manufacturers block the ability to run any other os than the one shipped. But that procedure that supposedly bypasses the old BIOS, but doesn't work. I'm stumped. I'm thinking Gateway and Microsoft conspired to prevent anything else ever running on this POS. Any suggestions?
