The last snapshot 20191228 again updated Grub2. My problem is, that the %posttrans script 'grub2-i386-pc-2.04-3.2.noarch.rpm' fails. /usr/sbin/grub2-install --target=x86_64-efi Installing for x86_64-efi platform. Could not prepare Boot variable: No space left on device /usr/sbin/grub2-install: error: efibootmgr failed to register the boot entry: Input/output error. Many users from different distributions had this problem too. The error message "No space left on device" is misleading. The real problem is, that there is a problem with the UEFI variables. Some users suggest to remove "dump" variables, but I have no such variable. # ls /sys/firmware/efi/efivars/ | grep dump # ls /sys/firmware/efi/efivars/ | wc -l 85 (source https://unix.stackexchange.com/questions/379774/grub-installation-failed) My work-around was to copy the new Grub2 EFI boot code. My PC boots with this change. # efibootmgr -v Timeout: 1 seconds BootOrder: 0002,0000,0001,0004,0007,0008 Boot0000* CD/DVD Drive BBS(CDROM,,0x0) Boot0001* Hard Drive BBS(HD,,0x0) Boot0002* Windows Boot Manager HD(1,GPT,a4b17afc-3db4-47b8-980f-bb3cec43d8c7,0x1a9c3800,0x64000)/File(\EFI\Microsoft\Boot\bootmgfw.efi)WINDOWS.........x...B.C.D.O.B.J.E.C.T.=.{.9.d.e.a.8.6.2.c.-.5.c.d.d.-.4.e.7.0.-.a.c.c.1.-.f.3.2.b.3.4.4.d.4.7.9.5.}...I_...............

My UEFI (Intel DH55TC mainboard, TCIBX10H.86A.0048.2011.1206.1342 from 12/06/2011, no updates available) is old and buggy. But what else could I try? My fear is, that one of the next Grub2 or Windows 10 updates will break the boot process.
