Removed /boot and /boot/efi

edit

Hello,

yesterday I upgraded from Fedora 19 to 20beta by fedup --network 20.

The update ran through, took about 2 hours and it upgraded about 3000 packages. So far so good, but the GRUB2-entry of Heisenbug told me that a magic value was wrong after the reboot.

So I booted a previous entry and tried to upgrade grub2-efi with yum upgrade grub2-efi. It said there is a new version, but the installation was not successful. I remounted /boot and /boot/efi as read/writeable and tried again. This time there was another error: "Disk space too low (required 6MB)"

When I installed F19 this year I accepted the values from the installer: /dev/sda1:/boot=200M, /dev/sda2:/boot/efi=500M. I thought this should be enough, but apparently the EFI-partition needs more space (?). So I used fdisk to delete both partitions and created two new: /dev/sda1 with 150M and /dev/sda2 with 550M. This should be enough to hold the new grub2-efi version. Or so I thought.

I knew that I had to reinstall grub2 because I removed the partitions. So I rebooted, started from Fedora 20-DVD but the rescue-environment couldn't automatically fix grub2.

I tried to install Fedora 20 from disk - a fresh install to say. I have 120GB unallocated disk space where I located fedora-root. /home is the same /home as before and the both boot partitions are created automatically. The installation stopped two times with a yum error "no more mirrors to try". It was not connected to the internet, so I don't know why it even tries any mirrors but at least both partitions are created. This time /boot was set to 200M on /dev/sda2 and /boot/efi was set to 500M on /dev/sda1 (switched from prior installation wizard).

I rebooted into rescue-enviroment (from installation DVD) and executed the following commands.

# mount /dev/fedora_pcname/root /mnt/sysimage
# mount /dev/sda2 /mnt/sysimage/boot
# mount /dev/sda1 /mnt/sysimage/boot/efi
# mount -o bind /proc /mnt/sysimage/proc
# mount -o bind /sys /mnt/sysimage/sys
# mount -o bind /dev /mnt/sysimage/dev
# mount -o bind /run/lvm /mnt/sysimage/run/lvm
# chroot /mnt/sysimage

I removed the newest kernel with "rpm -e --nodeps kernel-3.11.8-300..." and reinstalled it with "yum install kernel" and installed grub2 on /dev/sda

# grub2-install /dev/sda

This sounded good, so I tried grub2-mkconfig

# grub2-mkconfig -o /boot/grub2/grub.cfg
