YOSEMITE RECOVERY HD WON'T BOOT (clover install)...panic CPU

[zedoc]

Hi,

yesterday, i've messed up with my clover "config file" and BIOS settings so i reinstalled clover.
Yosemite boot is fine now but i've got a "PANIC CPU" when i try booting from the "RECOVERY HD" partition.
I can only boot from it (the RECOVERY HD) in "safe mode"

How can i repair it? (or recreate it)
Should i try reinstall yosemite from the RECOVERY HD booted in "safe mode"?

If you have an advice

Thanks

OK I've found the solution, my recovery HD was corrupt

The following did fix my issue:

• downloaded the yosemite installer (again)
• created a bootable installation (8GB USB) drive with yosemite (USB drive volume name is Untitled).

sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Yosemite.app --nointeraction
​

• Removing the not working recovery partition

diskutil eraseVolume HFS+ ErasedDisk /dev/disk0s3
​

• merging the free space with the Macintosh HD partition

diskutil mergePartitions HFS+ MacHD disk0s2 disk0s3
​

• Install (like you upgrade) Yosemite over your existing (Yosemite) installation and complete the installation procedure (I used the installer from the fresh created USB).

After the installation was completed I rebooted the machine and I was able to use the find my Mac option again (error related to the recovery partition was gone).
This worked for me, a small (typing) error might result in loosing your installation + data. Please be sure you have a good working backup before you start!
