I was about to post another bug report but found this one. Again, if the bug was fixed, it would have saved me about 3 hours on a weekend to get to the bottom of this. I don't know if 14.10 is going to have new iso files made or if it is possible to have efibootmgr automatically updated before installation process begins, but if it is, please consider updating the package, as it just plain brakes installation on UEFI systems and the nature of the problem is too complicated for anybody but an expert to resolve on its own.
POSSIBLE WORKAROUND: After 14.10 Live cd boots, connect to internet and perform the following: wget http://launchpadlibrarian.net/144695214/efibootmgr_0.5.4-7_amd64.deb sudo dpkg -i efibootmgr_0.5.4-7_amd64.deb efibootmgr -V # should report 0.5.4 proceed with installation after installation, verify that the downgraded package stayed in place efibootmgr -V # should still report 0.5.4 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1363719 Title: efibootmgr may create a duplicated boot entry, "breaking" UEFI boot.
