Well. Here I found a solution. For Debian, through Trisquel (based on Ubuntu: based on Debian). Both uses GRUB2 any way.
For what I heard (just opinions, they depends of hardware), is better to install OpenBSD in a first partition, and in the second a GNU system, if you want the dual boot. But is OK.
You have GNU on the first partition. Did you install OpenBSD in a second? Well, let's configure GRUB2 on Debian:
Quote:
|
$ sudo nano /etc/grub.d/40_custom
|
Immediately downside of comments (with those "#") lines.
Initial "..." are a “Tab”:
Quote:
menuentry "OpenBSD" {
...set root=(hd0,1)
...chainloader +1
}
|
If you have OpenBSD on the first partition, this section: “...set root=(hd0,
1)” stays like that. If it is not, just change, and put “...set root=(hd0,
2)”. If you have troubles, please tell me here.
When you get it, just "Ctrl+X", "Y" (yes), and "Enter". Changes saved.
Like root:
And then...
Quote:
|
# grub-mkconfig -o /boot/grub/grub.cfg
|
Almost done...
GRUB2 may ask you for a user to log into a Operative System partition. The user will be "
grub", but you don't know the password (five numbers).
You can use the password, by knowing it, or you can delete it by editing a configuration text:
Quote:
|
$ sudo nano /boot/grub/grub.cfg
|
When it says:
Quote:
### BEGIN /etc/grub.d/01_PASSWORD ###
set superusers=grub
password grub FIVENUMBERS
### END /etc/grub.d/01_PASSWORD ###
|
If you don't want any more the password requirement, do this (comment this lines):
Quote:
### BEGIN /etc/grub.d/01_PASSWORD ###
### set superusers=grub
### password grub FIVENUMBERS
### END /etc/grub.d/01_PASSWORD ###
|
"Ctrl+X", "Y" (yes), y "Enter". Changes saved.
NOTE: Do not try then
"sudo update-grub" or
"sudo update-grub2". If you do it the password may be reestablished.
Well. Reboot, and tell us how it goes!
