Doesn't detect existing Windows created EFI partition
Last modified: 2016-09-21 12:19:00 EDT
anaconda doesn't detect the existing Windows EFI partition resulting in a non-working "Windows Boot Manager" option in grub.
1. Factory restore a consumer computer with UEFI (Windows reinstall with all the partitions that go with it)
2. Shrink the main partition
3. Tell anaconda in the Live installer to automatically partition the now-free space.
grub as the default bootloader with a working Windows option
grub's scripts detect Windows as available, but the EFI partition with grub on it doesn't have the right Windows .EFI files. Trying to boot Windows results in a warning about "bootmgfw.efi" being missing (on top of my head) and the boot stopping.
Please attach the log files from the install. The log files are available in /tmp during the installation and copied to /var/log/anaconda on the installed system.
