So I can't even start the install.
I'm trying on a brand new PC, with latest i7, modern MB and everything brand new and latest models.
Booting from USB 3.0
After full shutdown and power on, all the partitions of the USB drive showed up in the bios. Then I just selected the specific partition instead of the drive in general and it went just fine after that.
I m trying with the 3.2 version on an old acer.
I also tried your technique but didn't work. Did you use F12?
Well I entered my bios with delete and then selected the partition 1 of the USB drive and was all fine after that.
