I seem to have this exact issue: "Initial install 19.04, dual boot with Win10, everything fine; Upgrade to 19.10, Ubuntu boots fine, Win10 does not"
On a fully up to date 19.10 install, however, I seem to have one difference: When I select in the grub menu to boot windows it throws an error similar to: "Alloc magic is broken at XXXXXX Press any key" It seems like the same issue, but from what I can tell, I have the updated grub2 packages and still have this issue. Am I barking up the wrong tree? grub-common 2.04-1ubuntu12.1 grub-efi-amd64 2.04-1ubuntu12.1 grub-efi-amd64-bin 2.04-1ubuntu12.1 grub-efi-amd64-signed 1.128.1+2.04-1ubuntu12.1 grub2-common 2.04-1ubuntu12.1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1845289 Title: Grub EFI amd64 no longer start EFI/Microsoft/Boot/bootmgfw.efi To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1845289/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
