Exceptionally, there is a respin of Ubuntu 17.10 and its flavours to fix bug 1734147 in the kernel which was leading users to be locked out of their BIOS settings.

This bug can be triggered merely by booting the live image without even
installing, and has the potential to make a user’s system unbootable either
immediately or in the future. While the affected machines are believed to
always be recoverable via software, this is not straightforward and is very
difficult to communicate to users who may be in the situation of having
their laptop no longer be bootable.
