Triple-Boot down after Sierra Upgrade

[PrenomNom581]

Hi everyone,

 

I'm MacbookPro's user and since my Os upgrade from El Capitan to Sierra, I lost refInd and my triple boot, so i've reinstall refind but only get dualboot with BootCamp ; I lost my Linux partition on refind.

 

When i look for diskutil, partition is here but information are not correct like filesystem format for exemple and I can't mount Volume.

 

Is there a simple way to reactivate this partition, to start with refind ?

 

 

In the picture you can see I have 2 SSD one for my DATA --> disk0 and one for OSs --> disk1 with partitions :

  - disk1s2 for Sierra,

  - disk1s3 for Linux,

  - disk1s4 for Windows.

 

I don't touch my linux partition before upgrade for Sierra and diskutil show file system as MS-DOS but Linux partition was formatted as Ext3.

 

Sorry for my english, I'am a french guy
