Re: [ubuntu-in] OT - Multiple Booting of GNU/LInux OS's
You can see which partition on each disk is marked as bootable from the fdisk outout i.e. the one with '*'. 1. When you say (hd0,1) it means 1st partition on 0th hard disk. So in your case you will have to specify (hd1,1). 2. You can see that root partition of your installation is specified with UUID. UUID is a unique identifier for every hard disk partition in your system. I am not sure if partitions on a USB disk will have same UUID everytime you boot. But if it is the case then you can boot into Ubuntu and find UUID for all partitions with command 'ls -l /dev/disk/by-uuid/'. 3. It is possible to dynamically specify kernel, initrd, and root in grub instead of trial and error on menu.lst. When you see grub menu of Ubuntu, press 'c' key. It will give you a command prompt. You can then give commands root, kernel and initrd. After that give command 'boot'. Ifthe parameter you have provided are correct it will boot in Mandriva. If now you can reboot machine by Ctrl + Alt + Del and try again. This way you won't have to boot in Ubuntu everytime. Once you have found correct values add those to your menu.lst Hope this helps.

Re: [ubuntu-in] OT - Multiple Booting of GNU/LInux OS's]
Ok i tried the following edited my /boot/grub/device.map to show the following (hd0) /dev/sda (hd1) /dev/sdb edited the /boot/grub/menu.lst as follows title MANDRIVA linux kernel (hd1,4)/vmlinuz BOOT_IMAGE=linux root=UUID=9be80552-9983-4062-b4da-1247596cbbae resume=/dev/sdb1 splash=silent vga=788 initrd (hd1,4)/initrd.img ** am not sure how the the hd1,4 should be should it be hd1, 1 or some other number. But this *does not work* i get the error 21 - device not found any tips ram -- ubuntu-in mailing list ubuntu-in@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-in

[ubuntu-in] OT - Multiple Booting of GNU/LInux OS's
Hi For the past few days have been wanting to try other distros's along with my existing Ubuntu 7.04. So i installed Mandriva 2008 spring on an external USB HD (my laptop supports booting of USB). For the second OS (being installed on the external usb HD) i made an additional /boot and pointed the grub loader to be installed on this section. However when i try and boot of the USB HD the boot loader does not appear. So a few questions : 1. Why does not the second OS work 2. Is there a way i can add the boot loader for the Second OS (Mandriva 2008) to my existing Ubuntu OS menu.lst. There was a possibility to ask the Mandriva to install the boot loader to the onboard HD section but it seems that Mandriva cannot / does not see all the existing OS's that are there. Currently my main Ubuntu 7.04 boot options are Ubuntu MS windows MS Windows (recovery) Mandriva sees only Ubuntu 7.04 and MS Windows The windows recovery partition does not appear. I tried copying a section of the USB HD's mandriva menu.lst to the ubuntu menu.lst, specifically the following lines title linux *(Mandriva)* kernel (hd0,4)/vmlinuz BOOT_IMAGE=linux root=UUID=9be80552-9983-4062-b4da-1247596cbbae resume=/dev/sda5 splash=silent vga=788 initrd (hd0,4)/initrd.img i could not figure out the hd* section so randomly changed it to hd1 and the device /dev/sda5 to /dev/sdb5. But while it showed up on the Ubuntu boot loader it just said that target device could not be found, when i tried booting to Mandriva. So will it work if the correct hd device is pointed to ?? and any idea how i find the correct hd device since both Ubuntu and Mandriva identify them separately. thanks ram PS I could post the menu.lst in case its required. -- ubuntu-in mailing list ubuntu-in@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-in
