Windows 8 does and it seems to be bootmgfw.efi as it looks on my laptop (it has 3 drives, 1 HDD for Windows, 1 HDD for Ubuntu LTS and Fedora, 1 SSD for the latest Ubuntu, all UEFI):

I mounted the ESP with `mountvol b: /s` in Windows, renamed the existing bootx64.efi and ran bcdboot, which created a new ~1.5 MB bootx64.efi- file. Unfortunately, this being another machine (another disk/partition layout or another license/edition) the hashes don't match. Also my experience from previously mentioned case is that manufacturers put a customized Windows loader in that location which tries to blend POST and Windows boot phase together by displaying the same company logo the whole time (probably to give the impression of a faster startup). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1366546 Title: Ubuntu doesn't provide \EFI\BOOT\BOOTX64.EFI for UEFI systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1366546/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
