How to repair Clover EFI

[leon321]

Hi

I am running a multi Mac Osx Os on a GA-X58A-UD3R.

6 months ago, I changed Chameleon boot loader to Chimera, and all worked fine.

Then, today, trying to fix an other HDD on this Hack, I killed something around EFI clover partition.

I presume this, because I can boot from Clover USB and select any OS that I can launch and run successfully.

Here is my disks list:

 hi$ diskutil list
/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *2.0 TB     disk0

   2:                  Apple_HFS Snow_Leopard            300.2 GB   disk0s2
   3:                  Apple_HFS Yosemite                299.8 GB   disk0s3
   4:                  Apple_HFS El capitan              299.5 GB   disk0s4
   5:                 Apple_Boot Recovery HD             650.0 MB   disk0s5
   6:                  Apple_HFS Mav10.9.5               300.0 GB   disk0s6

   8:                  Apple_HFS Spare                   499.4 GB   disk0s8
   9:       Microsoft Basic Data AVIRER                  133.2 MB   disk0s9
/dev/disk1
   #:                       TYPE NAME                    SIZE       IDENTIFIER

   2:                 DOS_FAT_32 TO PRINT                833.6 MB   disk2s2

 

Now I tried to reformat EFI partition,

newfs_msdos -v EFI /dev/disk0s1

Then reload it from a CCC archive

and reboot

 

I also tried to reinstall Clover using Clover_v2.3k_r3489.pkg

 

I still have this message at boot (from HDD)

Non System disk

Press any key to reboot

 

Please help

check you bios boot path to clover and set it if it changed.

Hi

I don't understand what do you mean

and how to check /modify it.

Could you explain ?

thanks

/boot in all osx partition are the same.

[leon321]

OK

May be I found what you mean:

editig config.plist with Clover configurator allow to see/modify default boot volume.

Here it is Yosemite.

So pb isn't here.

I found in clover wiki how to install ( re install ?) manually Clover

so I did :

bash-3.2# fdisk440 -f boot0af -u -y /dev/rdisk0
bash-3.2# sudo dd if=boot1h2 of=/dev/rdisk0s1
2+0 records in
2+0 records out
1024 bytes transferred in 0.000584 secs (1753764 bytes/sec)
bash-3.2# fdisk440 -e /dev/rdisk0
Enter 'help' for information
fdisk: 1> f 1
Partition 1 marked active.
fdisk:*1> w
Device could not be accessed exclusively.
A reboot will be needed for changes to take effect. OK? [n] y
Writing MBR at offset 0.
fdisk: 1> q

 

EFI partition is loaded from a backup,

so content must be OK.

 

If I reboot I still get

Non System disk

Press any key to reboot

 

Please help

does your efi show if you boot with boot selection menu when you press F12 at boot. also check in your bios hold delete key to enter into bios.

Hi

 

I finally install Clover in Yosemite partition manually and it works !

Impossible to use EFI....

 

Most important is that my Hack works again.

 

Thank for your help
