2018-09-18 08:04:29 Mathieu Trudel-Lapierre description package: shim-signed, shim release: Ubuntu 18.04.1 LTS version: shim-signed:amd64 1.37~18.04.1+15+1533136590.3beb971-0ubuntu1 shim:amd64 15+1533136590.3beb971-0ubuntu1 expected: grub menu loading xubuntu and windows in dualboot happened: loading xubuntu works, loading windows failes (no error - black screen - no hard disc light flashing) I uninstalled shim, shim-signed, disabled 'bionic-updates' and installed old versions shim-signed:amd64 1.34.9.2+13-0ubuntu2 shim:amd64 13-0ubuntu2 and boot works well like before. I enabled 'bionic-updates' and installed the newer versions without error and again chainloading of windows fails. [Impact] Dual-boot installs of Ubuntu and Windows 10, and other instances of chainloading another bootloader from grub2. [Test cases] 1) Install Windows 10 2) Install Ubuntu in a dual-boot setup with the existing Windows 10 install. (resize or install on a second disk) 3) Boot to the "ubuntu" entry in UEFI firmware. 4) Hold Shift to get the grub menu 5) Pick "Windows 10" at the grub menu Verify that the Windows 10 entry from grub menu correctly boots to Windows 10. Without the patch, there should be a "relocation failed" error message. With the patch, Windows 10 should start normally. [Regression potential] Regressions would show up as other cases of failure to load the bootloader that is being chainloaded to -- it is not noticeably different than the current failure more (which is also a failure to load the bootloader). Chainload is otherwise unlikely to affect the started loader. --- package: shim-signed, shim release: Ubuntu 18.04.1 LTS version: shim-signed:amd64 1.37~18.04.1+15+1533136590.3beb971-0ubuntu1  shim:amd64 15+1533136590.3beb971-0ubuntu1 expected: grub menu loading xubuntu and windows in dualboot happened: loading xubuntu works, loading windows failes (no error - black screen - no hard disc light flashing) I uninstalled shim, shim-signed, disabled 'bionic-updates' and installed old versions shim-signed:amd64 1.34.9.2+13-0ubuntu2 shim:amd64 13-0ubuntu2 and boot works well like before.
