grub-probe error

[Toshikazu Aiyama, Ph.D.]

I have installed Jessie on sda3 with grub, next CentOS7 on sda7 with grub, and then Wheezy on sda5 w/o bootloader.
All of these are 64-bit.


When I want to reflect the new addtion Wheezy, and CentOS7 under Jessie

# update-grub
Generating grub.cfg ...
Found linux image: /boot/vmlinuz-3.14-1-amd64

Found Debian GNU/Linux (7.6) on /dev/sda5
Found CentOS Linux release 7.0146 (Core)  on /dev/sda7

grub-probe: error: unknown filesystem.
Adding boot menu entry for EFI firmware configuration
done

Obviously complianing about CentOS7.  Jessie & Wheezy boot up OK. But not CentOS.  But I can boot up ftom CentOS's grub2.  But I definitely want to boot from debian grub2.

M/B: AsRock Z97 Extreme6

grub2 of CentOS7 complain nothing.

I have been a user of elilo, but I am contemplating to move to grub2.  Thank you for your attention to this report.
