Sorry Florian for the top-post.

Well, you were right !
The live-cd SysRescueCd showed all the devices switched ; sdb instead of
sda.
Renaming all the devices and system was booting again.
Nevetheless, i felt that with AHCI BIOS Mode, the SSD was slightly less
reactive than the IDE Mode.
Do you think that could be possible ?
May be, i am completely wrong...
