I have got this as well with latest update on Ubuntu 17.10 last week. I am running X1 Carbon Gen 5 really well until last week things got bad after running the software update.
The system keeps on rebooting with System BootOrder not found. Initializing defaults. Reset system I have tried the boot-repair but didnt help. Tried to set the boot order and boot in bios with no help. Reinstalled the root but seems to be not helping in any way. Here is the boot repair log http://paste.ubuntu.com/%3Dd9NfmbjBrM/ Has anyone managed to boot back with any workaround? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1747889 Title: (Acer Aspire V3-372) System not booting after update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim-signed/+bug/1747889/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
