Hi, tested again. Acer laptop Aspire E15 E5-571G EFI system 64GB USB 3.0 flash medium
Loaded F25 Alpha release Workstation dnf update kernel -> got Kernel x86_64 4.8.0-0 rc8.git.0.1.fc25 made -according to the production process- a successful F25 build on the 64GB flash medium Tried to boot -> again Dracut error with the warnings: - dev/fedora/root does not exist - dev/fedora/swap does not exist - dev/mapper/fedora-root does not exist When I looked with F24 onto the F25 build, most partitions did not exist, i.e. EFI partition was empty, also GRUB2 was nearly empty, the size of the F25 build was was about 1,1GB.

Otherwise the stick would bebooted by default, if present.> The internal drive for this machine dual boots Fedora 24 and Windows.> Only the external drive was used by Anaconda for the F25 installation.> It might be possible to update GRUB on the internal drive so it can boot> F25 from the external drive, but I rather like the present state where no> change was made to the internal storage medium.The boot manager aspects of GRUB are weak, it still depends on staticconfiguration rather than dynamic discovery. Discovery is difficult asos-prober's existence and history shows. There's a proposed standardto help, but there's no meaningful agreement on it among any of thestake holders.But yes, it's possible to statically get a boot entry into GRUB butthen it appears as if it's a valid option even when the stick isn'tpresent. If the stick has to be recreated/replaced, then that bootentry won't work.-- Chris Murphy_______________________________________________test mailing list -- test@lists.fedoraproject.orgTo unsubscribe send an email to test-le...@lists.fedoraproject.org
