[Bug 1091464] Re: Unable to chainload Windows 8 with Secure Boot enabled
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.

[Bug 1091464] Re: Unable to chainload Windows 8 with Secure Boot enabled
Hello Nicolas, thanks for your reply. Of course I read your comment #31 concerning the BIOS update... but regarding the fact, that the device is a) not mine and b) just about 1.5 years old, I have to admit that I'm a little scared about updating the BIOS and possibly damaging the device. From my personal experience, flashing a BIOS is not without risk. My intention was to provide another case and maybe more details. The bug is known for about 2 years now and it seems that nothing has happened so far, although other distros seem to cope with imperfect BIOS. This worries me a bit. Dual boot is a very important topic, especially with Ubuntu due to its appealing effect on people that think about switching from Windows. Sometimes I think, the objectives of development are a litte unbalanced... In the end, I prefer disabling Secure Boot to updating the BIOS. The laptop is intended to be used primarily with Linux (especially dealing with the internet), while Windows should be a backup for special software only. For me, possible security risks due to disabled Secure Boot seem less harmful than a) the owner using Windows or b) damaging the device while flashing the BIOS. After boot-repair totally cracked up everything (no more GRUB, whatever I did), the machine now runs 14.10.

[Bug 1091464] Re: Unable to chainload Windows 8 with Secure Boot enabled
I can confim this, too. Machine is a Toshiba Satellite C850D - 119. Windows 8 has been pre-installed. The regular user isn't satisfied, so a Linux install was desired. Nevertheless, Windows 8 will still be required. The regular user is of very poor computer know-how, so dual-booting via the GRUB menu should be fine, while having to perform several steps (going through the UEFI menus) isn't acceptable. I installed Ubuntu GNOME 14.04.1 after shrinking the windows main partition, left all of the other partitions untouched. The installation procedure went fine, booting Ubuntu from the GRUB 2 menu works very well. Booting Windows 8 from the GRUB 2 menu doesn't work unless secure boot is disabled. The idea of comment #25 also didn't work with secure boot enabled (same error message, as with original os_prober generated menu entry). Disabling secure boot is however a workaround. Booting Windows 8 from the UEFI boot menu works regardless of secure boot enabled or disabled. I didn't try rEFIned yet. I think, GRUB (or os_prober) should be able to handle this by themselves.

(Disclaimer: I am using Fedora because I couldn't get Ubuntu to install, but I observed the same behavior.)

Since this bug was filed, the shim signed bootloader has been updated several times in Ubuntu. Please test with a clean install from either Ubuntu 13.10, or a daily image of Ubuntu Trusty, to check whether this problem still exists with current versions. Also, you say the bootloader did not install when you used manual partitioning, and you subsequently used a third-party tool to configure the bootloader. The missing bootloader is probably caused by a wrong partition usage choice, and we can't support the output of the third- party recovery tool. Please use the guided partitioner to install Ubuntu side-by-side with Windows 8. If there are bugs in that standard install path, we need to know about them and fix them; and if your manual install went so badly that the bootloader wasn't installed, we need to rule out the possibility that the chainboot problem is related to this. -- 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

[Bug 1091464] Re: Unable to chainload Windows 8 with Secure Boot enabled
I don't have a fix for GRUB, but you *should* be able to work around the problem by using my rEFInd boot manager (http://www.rodsbooks.com/refind/): 1. In Linux, install the rEFInd Debian package. 2. Check the /boot/efi/EFI/refind directory. It should contain *either* a refind_x64.efi file *or* a shim.efi file and a grubx64.efi file. 3. If there's a refind_x64.efi file, rename it to grubx64.efi. That's rEFInd, despite the filename. 4. Download version 0.2 of shim from its download site (http://www.codon.org.uk/~mjg59/shim-signed/). (Note that Ubuntu ships with shim 0.1, which is useless for the procedure I'm describing.) Use either the shim-signed.tgz or shim-signed-0.2.tgz files; they're identical. Alternatively, you could use Fedora's or OpenSuSE's version of shim 0.2. 5. Copy shim.efi from the shim package to /boot/efi/EFI/refind, overwriting shim.efi if it's already present. 6. Copy MokManager.efi from the shim package to /boot/efi/EFI/refind. 7. Use efibootmgr to add shim to the NVRAM boot options, as in efibootmgr -c -l '\EFI\refind\shim.efi' -L rEFInd. (You *should* be able to skip this step if you installed rEFInd with Secure Boot enabled.) 8. Reboot. You'll see the MokManager menu appear. Use it to add the keys for both rEFInd and Canonical to the MOK list. (If you have the right software installed, the rEFInd installer will re-sign the rEFInd binaries with locally-generated keys, in which case you should enroll your local public key instead of or in addition to the rEFInd key. IIRC, it's called refind_local.cer.) I'm afraid the MokManager user interface is dreadful; it makes an Apple II's UI look advanced. All the keys should be in the EFI\refind\keys directory of the ESP, which is probably the first partition in the list. You need the .der and .cer keys. 9. When you exit MokManager, the computer could boot Windows, launch rEFInd, reboot, or even hang. If it does anything but launch Linux, reboot. 10. When you reboot, rEFInd should come up as your default boot manager, and it should enable you to boot either Linux or Windows with Secure Boot active. You can verify that Secure Boot is active from the rEFInd information screen. (Check the platform line.)

[Bug 1091464] Re: Unable to chainload Windows 8 with Secure Boot enabled
A second workaround, more convienent than the USB boot is to invoke the EFI device select menu, select HDD, then select ubuntu or Windows (both of which work). The ubuntu selection starts grub, but from grub, the Windows boot still fails with the above chainloader error. With the number of different brands mentioned in this bug, I begin to doubt the problem is vendor related. Maybe something we did caused this, so here's what I did: My first install was to a USB stick without ann EFI partition( used HD EFI, booted Ubuntu OK, did not boot Windows, and killed the Windows boot off the hard disk when not present). Installed to (prepared HD) in this condition, worked, but got a grub install error (Windows boot worked again). Installed to USB again after putting on a EFI partition, the install still mounted the HD EFI, which I manually unmounted and replaced with the USB EFI (this worked). At this point, the HD /EFI/ubuntu directory was corrupted, so had to manually delete it and replace the signed binaries. The USB would boot Ubuntu, but not Windows, and the HD would boot Windows (default). Using efibootmgr -v, I could see that the ubuntu boot was set up wrong, trying to boot grub instead of shim -- but much to my surprise, it still booted, so I surmise a silent failure, then a fallback to the /EFI/Boot/bootx64.efi (which was a copy of shim) which succeeded. I manually added (grub-install --uefi-secure-boot /dev/sda) a correct shim boot path, which worked too. I normally now enter F12 to select ubuntu or Windows. Not a totally clean history, but on the other hand, the machine has never been out of secure boot, I have never run boot-repair, and the only EFI variable manipulation I have done is through grub-install. -- 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

I have the same error on a Toshiba Satellite S855 S5378 with Windows 8 preinstalled.

Windows boots attempted from the thumbdrive, give the error message.

[Bug 1091464] Re: Unable to chainload Windows 8 with Secure Boot enabled
I face the same problem on an Ultrabook Series 5 laptop and confirm that items 8 and 9 do work as a workaround as described. However, after realizing this, I started digging into a riddle why Ubuntu fails to load the 'samsung-laptop' kernel module in the UEFI mode and actually bumped into bug #1040557, a bug that should have been flagged 'nuclear' instead of 'critical,' as comment #114 puts it. Hence I decided to stop at this point for the time being and wait for reports that it is safe to use Ubuntu on my machine. -- 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

On my Samsung Series 9 device I do have the exactly same behavior. I documented this in my blog post: http://falstaff.agner.ch/2012/12/18/ubuntu-12-10-and-windows-8-with-secure-boot-mode/ However, I observed that my original Windows Boot Manager has a slightly different file path: Boot0008* Windows Boot Manager HD(2,96800,32000,f1fdeac1-d057-4f3b- 9f66-6f74eb3b469b)File(\EFI\Microsoft\Boot\bootmgfw.efi) compared to Grub: /ACPI(a0341d0,0)/UnknownMessaging(12)/HD(2,fa800,96000,372001a2fb07f544,a3,ff)/File(\EFI\Microsoft\Boot)/File(bootmgfw.efi). However, the same menu entry works if I disable Secure Boot.
