What does the screenshot you attached have to do with the bootloader? That looks like a dependency problem, and thus a problem with the repository. Please attach the log files from the install to this bug as individual, text/plain attachments.

Hmmm. When booted system I got:

Tell me where those logs are on installed system (or how to get them during installation) and I will provide them on Monday.

They are copied to /var/log/anaconda on the installed system. During installation they are available in /tmp.

anaconda.log says

19:21:11,553 ERR anaconda: bootloader.write failed: failed to set new efi boot target. This is most likely a kernel bug.

(Also, please switch back to English messages for reproducing / reporting bugs.)

Then, program.log says

19:21:01,156 INFO program: Running... efibootmgr -c -w -L Fedora -d /dev/sda -p 1 -l \EFI\fedora\grubaa64.efi
19:21:05,541 DEBUG program: Return code: 1

More information is necessary from efibootmgr (error message eg.)

I did new installation without removing UEFI boot entries. Everything went fine and system rebooted to freshly installed Fedora.

[root@localhost hrw]# efibootmgr 
BootCurrent: 0000
Timeout: 2 seconds
BootOrder: 0002,0000,0001
Boot0000  USB GRUB
Boot0001  Rawhide
Boot0002* Fedora

Upgraded to 0.13 firmware and did test installs.

1. UEFI has 2 boot entries

Fedora 21 alpha installer added 3rd option and rebooted to freshly installed F21. No issues.

2. UEFI without boot entries

Before installation I went to UEFI boot manager and removed all entries. Then booted installer. Installation went fine and then:

13:09:34,845 ERR anaconda: bootloader.write failed: failed to remove old efi boot entry.  This is most likely a kernel bug.

After reboot there were no boot entries defined. Grub is properly installed and boots but boot entry needs to be added.

Reopening, this is still happening in TC2.

With F21 TC2 this only occurs when 'PXE' is the first menu entry in uefi (including when it is the sole entry, or another installation is listed second). It does not occur when PXE is listed second in the uefi boot menu, or there is no boot entry at all. After the installation failed to remove the boot entry and continuing the installation the system reboots with no boot entries listed.

Grabber RC1.1 image. Did two installations. First one was with one boot entry present. F21 got installed and after reboot I landed in F21 nicely. Old boot entry was preserved.

Removed all boot entries and did second installation. After reboot EFI read F21 boot entry and booted just into F21 system.
