Hello Taihsiang,

We've seen similar reports for this issue during the past weeks. Every
time, the BootCurrent entry has no associated BootXXXX entry. I looked
in the UEFI spec and it's still unclear to me if this is a stretch or a
broken implementation.

That said, based on the number of reports, I believe we should still do
something about it. As far as subiquity is concerned, I don't think
trying to set the install media as the first boot entry makes sense so
I've disabled the behavior in
https://github.com/canonical/subiquity/pull/1671

I'd still argue that curtin should do the right think on "broken" UEFI
implementations if we can.

Thanks,
Olivier
