I’m selecting the Finnish locale and keyboard layout here, YMMV.
- With the Try Ubuntu option selected, hit ‘e’ to enter the boot parameter editor
- Go to the end of the line with linux kernel boot parameters (they perhaps end with
quiet splash --) and add these parameters:
locale=fi_FI console-setup/layoutcode=fi(so that, if the previous example holds, it now ends with
quiet splash -- locale=fi_FI console-setup/layoutcode=fi)
- Hit Ctrl-x to boot
