Hi I tried to make a dual boot with pepper mint and linpus on my AA1. I did this by shrinking the linpus partition and installing peppemint in the free space. Now the problem is that I cant boot into linpus, there is no option to do so. I think I need to edit something in grub but I dont know what. I’d appreciate it if someone could help.
I assume you can boot into Peppermint.
Try to install os-prober (if not already installed)
by running the following command in the Terminal:
sudo apt-get install os-prober
then update grub:
sudo update-grub
This will scan the hard disk for other operating systems and add them to the boot menu.
After doing what SeZo says, and waiting till the command line leaves you back at an $ prompt … reboot, and see if you’re offered both OS’s.
if not, boot back to Peppermint, open a terminal (Ctrl+Alt+T), and send the output from:
sudo fdisk -l
and
sudo blkid
and the contents of:
gedit /boot/grub/grub.cfg
os brobber and update grub did’nt work
output requestef is below:

os brobber and update grub did'nt workQuick question: Do you get a grub menu at boot with Peppermint listed but no Linpus?
No it just goes straight into peppermint
OK try this:
gksudo gedit /etc/default/grub
Comment the next two lines (put a # in front of them):
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
Save and close
sudo update-grub
Then reboot.
Does the grub menu now showing up?
the grub menu now shows up but linpus is not an option. There is peppermint, peppermint recovery, and two memtests or something.
Yeh there’s no stanza for linpus in grub.cfg … when I can get at my other PC that has an image of linpus, I’ll try to work out how the stanza should read … then come back to this.
It may not be today though.
[EDIT]
Meanwhile it probably would help if you download and run the boot info script:
http://bootinfoscript.sourceforge.net/
run it … then attach the RESULLTS.txt file to your next posting.
Thanks for your help so for
See the edit in my last posting … if you need help running the script, just ask.
Here’s the instructions for downloading and runnig the bootinfo script, just in case …
Open a terminal (Ctrl+Alt+T) and run these commands in sequence:
(and remember, Linux commands ARE case sensitive)
cd ~/Desktop
then
wget http://heanet.dl.sourceforge.net/project/bootinfoscript/bootinfoscript/0.61/bootinfoscript-061.tar.gz
then
tar -xvf bootinfoscript-061.tar.gz
then
sudo ./bootinfoscript
you should now have a file called RESULTS.txt on your desktop … attach that file to your next posting.
Then feel free to delete that stuff from your desktop if you wish.
I have attached the file to this post. I dont know why it say Windows XP for sda1, I have never had that OS on this machine??
Can you sednd the output from :
mount
/dev/sda3 on / type ext4 (rw,errors=remount-ro)

OK, let’s try to mount the Linpus partition, then update grub … with a little luck os-prober will then pick up the Linpus installation and add it to the grub boot menu.
first lets make a mount point:
sudo mkdir /mnt/linpus
now try mounting it:
sudo mount /dev/sda1 /mnt/linpus
(if there’s any output from that last command … post it here)
if not, what’s the output from:
ls -a /mnt/linpus
?
It does not mount i get this output:
sanish@AcerAspireOne ~ $ sudo mkdir /mnt/linpus
[sudo] password for sanish:
mkdir: cannot create directory `/mnt/linpus': File exists
sanish@AcerAspireOne ~ $ sudo mount /dev/sda1 /mnt/linpus
mount: /dev/sda1: more filesystems detected. This should not happen,
use -t <type> to explicitly specify the filesystem type or
use wipefs(8) to clean up the device.
mount: you must specify the filesystem type
sanish@AcerAspireOne ~ $ ls -a /mnt/linpus
. ..
sanish@AcerAspireOne ~ $
Hmm … wonder whay that’s there …
Anywho, try it with a different mountpoint
first lets make a mount point:
sudo mkdir /mnt/linpuslite
mount it
sudo mount /dev/sda1 /mnt/linpuslite
(if there’s any output from that last command … post it here)
if not, what’s the output from:
ls -a /mnt/linpuslite
?
The reason it said
mkdir: cannot create directory `/mnt/linpus': File exists
is because I tried the whole thing twice. So making another mount point wont work.
EDIT:
Do you think it is because the peppermint partition is ext4 and linpus is ext2?
OK, try:
sudo mount -t ext2 /dev/sda1 /mnt/linpus
what’s the output from that ?
[EDIT]
Do you think it is because the peppermint partition is ext4 and linpus is ext2?
Simple answer … Nope … it should be able to recognise an ext2 partition without issue … I’m guessing it’s down to the weird union filesystem overlay that Linpus uses for adding an (FAT32) SDcard to the main file system.
Have you got an SDcard inserted ?
