Re: Invalid signature in GRUB

[Hilmar Böhm <mls%hiro-consult.de@localhost>]

Hi,

I use this entry in /etc/grub.d/40_customfrom a Debian 8.2 on the same 
disk (sdb7):

-------------
....
# NetBSD 7.0 on /dev/sdb8 (wd1a)
menuentry "NetBSD 7.0 on /dev/sdb8 (wd1a)" {
        insmod ufs2
        set root=(hd1,msdos8)
        knetbsd /netbsd --root=wd1a
}
----------------

Then: update-grub or grub-mkconfig

/ Hilmar.
