holas!

you know? now I have installed slacko 533 4g (it has r128 and 1024x768 resolution! nice!). Also I have installed ubuntu 10.04 lts (believe or not, this os works very good too)

I think is good to learn about other distros. so first i installed ubuntu and later slacko

this ubuntu use grub2. some say grub2 can boot from iso files and can do many other things... so I would like to use grub2 to boot slacko and ubuntu

some say updating grub2 can automatically recognize the os installed on hard disk, but when I use the command: sudo update-grub2 the menu only show the lines for ubuntu

as i told you previously slacko is installed on hard disk (full installation). so how can I boot it using grub2?

thanks!

I've got a spare machine with TinyCore, Puppy 5.33, Mageia and Mint running, with grub2 from Mint controlling startup all working quite happily - and I'm a newbie and a grub2 novice!

You need to make appropriate entries in the 40_custom file found in /etc/grub.d folder, and then run sudo update-grub.

The 30_osprober script runs to see if it can detect other OSs but it doesn't always pick up other Linux distros. I rename it and make it non-executable to stop it running and manually put entries in the custom file which gets inserted in the main grub config file.

I'm at work so I haven't got access to my entries, but when I get home I will post my menu setup if you wish and see if that works for you.

Hi Idp!

you are right, I have to to edit the 40_custom file, then update grub2

but I dont know how to do it, because I already have installed slacko on the hard disk (full installation). when I search on the web, just there are methods to boot puppy linux from iso or frugal installation, also some say if there is a little mistake within grub2 then appear errors...

I hope you have the solution. bye

What you need to add is the following:

menuentry "Puppy (on /dev/sda2)" --class gnu-linux --class gnu --class os {
insmod part_msdos
insmod ext2
set root='(hd0,msdos2)'
search --no-floppy --fs-uuid --set=root 80a1b24e-f35a-45c0-9883-54d50e12b6b7
linux /boot/vmlinuz root=/dev/sda2
}

Change the partition information to match where you done your full install.

The set root='(hd0,msdos2)' line needs to reflect the correct disk and partition (disks start at 0, and partitions start at 1)

Find the device uuid and replace the one above with yours (i think you use 'blkid /dev/your_install_partition' to get the uuid.

And the final line should end as root=/dev/your_install_partition

As an aside, I renamed (actually copied) the 40_custom file to 19_custom so in ran before the 'memtest' entries that appear in the grub list.

Let me know if it works.

hi Idp!

I have been trying your help, but it doesnt work yet (first i copied all your lines, then I did some changes and saved and closed the custom file; after updating grub2, the grub.cfg can show the changes, but when the grub2 appears there is no line for slacko).

Look I have ubuntu and slacko within extended partition. ubuntu: root=sda5 (ext4), home=sda6 (ext4) swap=sda7 (linux-swap); slacko: root=sda8 (ext4). Also I created and installed slacko using the livecd

hi shinobar!

of course, I can find '/mnt/sda8/boot/vmlinuz'.

the installation is ok. just I need a line to boot slacko from grub2

do you know other ways to update the grub2?

bye

I am very interested in grub2 and dueal and triple booting.
But sadly I know too little.

I saw a text yesterday that suggested that one do changes
to a file named 30_os-prober. I can not find it now.

I used search but maybe it has not indexed what where written yesterday?

The suggestion as my poor memory recall vaguely is like this.

30_os-prober fail to accept Puppy. The script of 30_os-prober is not
made to deal with Puppy. Only for more known Linux it seems
so he suggested that one make this file inactive.

As I see it that is a very drastic measure. I wish I could find it again.

I would hope that we find other solutions.

I've found one reference to shutting of 30_os-prober now here

shinobar the following is no criticism of you personally at all.

But seen from the linux user this suggestion you have here will not do.

Linux Mint and Ubuntu is the most known Linux distros on DistroWatch
and they make use of grub2 for their install of their OS.

So grub2 for Linux is a given.

Sure Barry and You and other developers does not have to accept
and they can choose grub4dos or some other OS loader instead.

But that leave us noob users in a state of limbo.

Neither Ubuntu nor Linux Mint would care for Puppy frugal install
on grub2 so we would end up with two grubloaders.

The original grub2 that LinuxMint installed and then the Grub4dos that
you suggests and then when one update grub2 from Linux Mint
which happen automatically then it mess up the booting.

Some have in forum for LM told that they don't find any entry
for the other linux due to LM hide it.

So my personal view as a noob user is that Puppy place a lot
of complication on the new user due to grub2 get neglected.

I agree that is a priv of being a Developer that he or she is Boss
and the user can only make wishes and express a need and
have no way to persuade the Dev to comply

My thoughts goes to the noob that has to deal with two different grub.

I agree that Puppy has no reason to go over to grub2 at all.
But to not make effort to find a good solution to dual boots
that would not be user friendly?????

Yes I did anticipate that you would give me that comment.
Remember my post where not intended to criticize you personally.

I dearly hope you remember how happy and thankful
I where when you took time to help me find Ms Windows
in grub4dos. So I do appreciate and I am deeply thankful
for your generous sharing of your knowledge and taking
personal time to give me good advices to get grub4dos to
work for me personally.

What I try to refer to here is what happens to a noob or
a noob like old timer like what I am.

Is it some 3 years now we have had these questions on the forum
in reference to dualboot with Ubuntu and Puppy and maybe
triple boot with Win7 and Ubuntu and Puppy relating three
different bootloaders to each other for a noob.

What I refer to is how it feels like and the complication level
for us noobs to get this to work.

I have for some 3 years really spent many many hours to get
puppy to work with grup2. Now I am an absolute noob and
a total idiot when it comes to getting logic and structure of linux
and booting.

What I can agree with is that each OS has to take care of
how they relate to the needs of their users. .

1. Ms Win has to decide on their users.
2. Ubuntu Linux has to decide on their users.
3. Puppy Linux has to decide on their users.

Ms could say that they want a monopole and therefor
could not care less about Linux users.

Linux OS is supposed to be supporters of FOSS and many of
the developers does support Linux as an alternative.

So as a noob one expect the Linux crowd to be cooperative.

Yeah I know I am very naive.

What I talk about is not that grub4dos can laod a already installed
Linux Mint. That do work. What I talk about is that we need to
provide the new Puppy user with knowledge about how to protect
Puppy from getting invisible due to how LM works when it automatically
update the grub2 when it does their security upgrades.

Yes I agree that none of the Puppy Devs has to do this personally.
What I talk about is us users care and friendly relations to the noobs
of using Puppy. The Devs are their own Boss so they could not care less.

hello?

ok guys. please this post is about how to boot slacko using grub2. I mean I want to use the grub2

I have been trying again and cant do it yet.

under ubuntu I can enter to the partition where I installed slacko (sda8-ext4), so there are all the directories and files, so everything is ok

I hope someone can help me. bye

[nooby]

Yes sorry my careless comment went down the wrong rail.

Back on track with two links.
