- finally found that only my sata hdd can boot with the appropriate bios settings (not the ones previously used): only ahci works
- but the pata hdd still refuse and i get "alloc magic is broken at ..." I've tested that disk and there is no error or warning (fsck & smart)
- thats is curious as some users with pata hdd have no problem: so it might be all about chipsets differences. Could it be related to ram ? ram test passed here.
So now i will purge grub2.0 everywhere and reinstall only the precise 1.99~21ubuntu3.1 for now. I'm tired of the grub design when having a multi boot: you simply cant boot if grub is broken on the master partition (here too a grub failsafe, aka a second working partition choice should help a lot)
i'm booted again with Precise:
