BIOS Insyd 6.60 EFI version 2.31 by INSYDE Firmware 6.10 Toshiba Satellite S955, UEFI with Secure boot disabled. OS 64 bit Ubuntu 14.04.2, running kernel 3.19.8-992-generic Dual boot with Windows 8.1
After a Windows 8.1 update 7/8/2015 (two important updates, all optional (2) ignored, the EFI boot order is for each boot, always returned to the default order with Windows first. This machine has been running 14.04 for a year, and I have successfully changed the boot order before. Ubuntu may still be selected at boot time (F12, select hdd, then select ubuntu) and it successfully boots., efibootmgr can still alter the boot order to put ubuntu first, and reorder the USB/Net entries: (ubuntu, windows, USB, DVD, Net). Checking the order with another "efibootmgr -v" shows the new order, but a reboot will have the origial EFI order restored: Windows,Ubuntu,Network,USB,DVD The EFI Settings order was unchanged from USB, DVD, HDD, NET. The ubuntu entry had the name "ubuntu", and that still works when selected from the EFI device/os selection (F12). Looks like some nvram entry was changed by Windows to force the order reset at each boot. The efibootmgr reordering only changes the "Boot Order" variable (as named by "fwts uefidump". There are other variables, like Physical Boot Order, which might need changing to make the boot order permanent. I am examining the differences on the fwts uefi outputs from before the problem and now, but at first pass, nothing obvious turned up. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1286388 Title: changes to the boot order made via efibootmgr are not sticking To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1286388/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
