I have some new mostly positive findings about the boot failures concerning my HP ZBook 15, the 1st generation (2013). Importantly, it has the latest available BIOS installed: L70 Ver. 01.33 . (You may look at my bug report #1312318 .)
1.) The issue affects also ubuntu 14.04.3 LTS. 2.) The issue, at least for the LTS version of ubuntu, can be SUCCESSFULLY AVOIDED by setting the UEFI BIOS to the native UEFI, not to UEFI Hybrid mode. At the same time I turned on the Secure Boot (it was off during my previous attempts). So, my installation of ubuntu 14.04.3 with these two settings was successful, i.e. I was able to boot the installed system without any hassle. I did not check if both of these two settings (Native UEFI and Secure Boot) were necessary. I just used both of them and it worked. My guess is that ubuntu 15.10 would behave in the same way. So I think that THE BUG COULD BE CLOSED. 3.) Before the ubuntu 14.04.3 installation I tried also several installations of Linux Mint 17.2 . (a) This system can boot also in Legacy BIOS mode. I successfully installed the system in this mode. Unfortunately, the legacy BIOS still has bugs which prevent the control over the display brightness (see my bug report #1312318 .) (b) I tried also the installation with the Hybrid UEFI (and Secure Boot Off). The result was the same as with ubuntu 14.04.3 and also 15.10. (The systems could not boot in a usual way, just through the annoying Esc, F9, etc sequence.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1411017 Title: No bootable image was found.
