Thread: Dual Boot question....

  1. #1

    Dual Boot question....

    OK, I have been running Knoppix on a HD for about a year I guess, the program is 7.0.5, and I have been having some issues with it and Wanted to upgrade to 7.2 after I got all of the files from the old system.

    The problem is that when I installed the new program I expected the installer to ask if I wanted a dual boot grub or at least create a second boot option in the existing grub, but that didn't happen, and after getting the installation done I was unable to boot the new installation.

    I thought that I could maybe use the linux boot repair to change the program to a dual boot, and boot both of them from it, but, it just created the grub anew and now I can only boot the new program and not the old one.

    What do I have to do to get both of these programs to boot from the grub, so I can transfer files and get information on what programming I need install from the old program until I have it all rebuilt in the new program. I have tried finding the files from Iceweasel for the favorites folder, and they just don't seem to be anywhere I can retrieve them, and no access to the menus to see what programming I need to install so I have to be able to access both to transfer everything over. How do I link the grub to both?

    Please tell us in which partition of your HD you had installed the old version of Knoppix (7.0.5) and in which partition you have now installed the new version (7.2). What is the ouput within a terminal of
    Code:
    fdisk -l
    Code:
    mcedit /boot/grub/menu.lst
    and
    Code:
    uname -a

    The old program is sdb1, and the new is sdb2. The sdb drive is an SSD, sdb3 and 4 are of course the swap files accordingly.

    fdisk -l is: WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted. Disk

    sorry about the lack of separation on these posts, but, your program keeps deleting the spaces and and lines between the information and because you limit the time to edit to so little time I have left them the way the program posts them. appearantly even if I try to edit it will still remove those spaces and lines.

    Use double "new line" for new section.

    You can use the "Go Advanced" button to have more abilities to format the posting; before sending your posting use "Preview" to see how it looks like.

    If "noscript" (within Iceweasel/Firefox) is active for http://knoppix.net/forum/ disable it for this website; otherwise you cannot use the format abilities.

    Below the editor area is the "Additional Options" area. With "Attachments => Manage Attachments" you can upload images and after this insert them in your posting.

    "mc" and "mcedit" had changed the location for the personal configuration files; therefore the unclear message. Start mcedit once more and it will work.

    OK, here is mcedit, and I have disabled no scripts for this website so we will see how it does now.

    To insert the boot option for the old installation start with
    Code:
    su
    mcedit /boot/grub/menu.lst
    and insert this three lines

    title KNOPPIX old installation
    root (hd1,0)
    kernel /boot/vmlinuz root=/dev/sdb1 (.. and rest of this line)

    Save with F2 and quit mcedit with F10. By the way "lang=" has no language declaration.

    (.. and rest of this line)
    by this you mean the line from fdisk above in frame three above? The disk coordinates for the programming?

    instead of this insert all the same as in the 3rd line of the block

    title KNOPPIX
    root (hd1.1)
    kernel ...
