Problem installing ubuntu linux in virtual machine. Unabled to boot?

Question

linux

Here's the problem (screenshot below). Bios virtualization is enabled. PAE/NX - checked. How to fix?

Answer 1

the architecture must match
you installed x86-64 and in the settings of the virtual machine you chose 32-bit i686
go to the settings 'general' -> 'version' and change
if your host system is 32-bit itself, and you really need it, then only the software remains qemu virtualization will be 10 times slower (the operating system can generally run for 15 minutes)
