Boot Ubuntu [Solved]

[00110111]

Hello. I just got Sabayon last night, and I was wondering how I can boot into my Ubuntu here is my grub.conf that Sabayon generated:

Code: Select all

# grub.conf generated by the Sabayon Linux Installer
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.

#          kernel /kernel-genkernel real_root=UUID=957eeceb-f995-40d8-ba81-f569fb6e9404
#          initrd /initramfs-genkernel
#boot=sda
default=0
timeout=6

I am wondering how to edit this file to allow me to boot into Ubuntu. Ubuntu is on dev/sda7.

[joeoden]

Copy the Ubuntu entry from grub.conf (or menu.lst) on dev/sda7/boot/grub and then paste it as root into your Sabayon grub.conf (not menu.lst) save and the reboot.

Tip! If you haven't done so already create a backup image of all your partitions (I use partimage) also if you plan to update Sabayon create an image of your sabayon partion before you update (at least you can restore it instead of reinstalling when something goes wrong)
Have fun learning Sabayon (I am)

Could you give me an example? I tried that already, but it didn't work.

Hello there,

Could you also paste your ubuntu grub.conf and the output of fdisk -l for us? Also, do you use a separate boot partition, or do you just have /boot as a folder off of the root partition of your disk? Most likely you'll have to copy your kernel, initial ram disk, and system map from ubuntu's /boot to Sabayon's in order to boot them both with minimal effort. Or you could just have Sabayon's grub look in Ubuntu's /boot for the kernel files. We'll know more once you show us your other grub.conf and fdisk -l

Fist off sorry about the typo's in my last post

Just like yourself I am new to Sabayon and have made the switch from MS

I don't have Ubuntu but do have Scientific Linux and Debian installed (they do boot from my Sabayon grub.conf) I also use the KDE GUI so I suggest you start Sabayon by selecting KDE 3.5 from the Session menu before you login, unless you know how to use a file manager as super user under Gnome.

My example is the way I prefer to edit the config files and is not necessarily the correct way but it works for me.

I don't know how much you know about using the GUI the assumption is you don't, so I apologize for making the example to simple apart from adding snapshots and for still using some MS terminology.

Click = pressing the left mouse button once

1. Open Konqueror as superuser
Click on the kde Menu button then navigate to System, More Applications and click on File Manager-Super User Mode
The password dialog will appear, type your root password and press Enter or click OK, Konqueror will open in a window

2. Click on the System button
That is if it is not already selected on the Left Tabs, left hand side of Konqueror in the Navigation panel

3. Click on Storage Media
Then click the reload button or press the F5 key (because nothing is displayed in the right hand side of Konqueror)

4. Click the + next to Storage Media in the left hand side of Konqueror

5. Find your /dev/sda7 in the left hand side of Konqueror
If you don't know how, hold mouse over each media entry for a few seconds until the Tooltip pop-up appears (System:/media/sda7)

6. Click the + next to your /sda7

7. Click the + next to boot

8. Click on Grub

9. Double click on grub.conf or menu.lst in the right hand side of Konqueror
The file will open in Kwrite

10. Highlight your Ubuntu entry
If you don't know how to highlight, just click and drag starting from title to the end of the entry or to the beginning of title of the next entry (if you want or don't have a center mouse button you can right click on the highlight selection and click on copy in the context menu)

11. Then make the Konqueror window active (click on it or select from Taskbar)

12. Click on the Root Folder button on the Left Tabs (the red folder), left hand side of Konqueror in the Navigation panel

13. Click the + next to boot

14. Click on Grub

15. Double click on grub.conf in the right hand side of Konqueror
The file will open in Kwrite

16. Now go to the bottom of your grubconf and start a new line (click at the end of the last entry, then press the Enter key)

17. Now just Center mouse button click (this will paste your highlighted Ubuntu entry from the grubconfig on your /sda7
If you haven't a center (wheel) mouse button then just right click at the start of the new line and click on Paste

18. Close the file saving the changes (save dialog will appear asking you what to do when you close file)

19. Close all other open windows

20. Restart computer (logout, shutdown, restart)

Your new entry will now be displayed and you should be able to boot to your new entry.

Hope it works for you
If doesn't, do what xlnagla asks

Thanks a lot joeoden! All I needed was an example of what would boot, like your grub.conf file. Sorry you had to go through all of those instructions, but all i needed was an example. I am sure it will it someone else googling the subject though.

[joeoden]

Not a problem, glad I could help.

Don't forget to mark as solved.
