What model of laptop? What's the processor? I ask because I had a similar issue the other day with an old Intel Baytrail notebook where the UEFI is 32 bit and the processor is 64 bit - using a Debian multi-arch installer worked. I used the one with firmware. Happy to help on a reply All the very best, as ever, Andy Cater
