This is the first case reported here of the bug in (k)ubuntu 15.10, the newest ubuntu family as of October 2015.
I can confirm the bug exists in a Toshiba Satellite C850-19D laptop, with pre-installed Windows 8, and parallel installation of Kubuntu 15.10 "WIlly Werewolf". Same as other cases above, Kubuntu 15.10 installed very well and boots OK from Grub2 menu, but Windows 8 does not boot from this menu, showing instead the error "/EndEntire filepath: /ACPI(a0341d0,0)/PCI(2,1f)/Sata(0,0,0)/HD(2,e1800,82000,cc51b24f9affe111,2,2)/File(\EFI\Microsoft\Boot)/File(bootmgfw.efi)/EndEntire Cannot load image" Note the following: 1. The original workaround of disabling Secure Boot in the BIOS works in this case, and it is very easy to reproduce the issue. I have decided to stay without Secure Boot, as it is the simplest of all the workarounds so far. 2. Following advise from NVieville on post #48, since this is a Toshiba Satellite C850, I did a BIOS upgrade to the latest version for this model: v6.80, from 22-Jan-2014. I repeated the experiments and saw no improvement, i.e., the problem exists exactly the same with the new BIOS and I must disable Secure Boot to get Windows 8 booting. 3. A side note but useful: For those interested in Linux (Ubuntu) support for this Toshiba Satellite model, good news: All hardware is supported and working fine out of the box, no need to do any special or additional procedures: Wi-fi, sound, all FN keys, etc. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1091464 Title: Unable to chainload Windows 8 with Secure Boot enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1091464/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
