    Re: HowTo: Revert from grub2 to Legacy Grub.

    Very useful, thanks, it's saved me time looking things up.

    I have just installed Lucid and have to revert because as far as I can see there is now no way to pass kernel params via grub. Easy as with Grub Legacy. Just add in menu.lst

    Now if the effort had been put into some better error handling. What does error 15 mean, or error 13.

    Re: HowTo: Revert from grub2 to Legacy Grub.

    Grub2 is more complicated that what it should be. Whereas in Grub1 all you had to do is edit menu.lst and all the options were there, in one spot, in Grub2 you have a multitude of scripts, with the options buried deep in them. All I wanted to do is require a password for booting into Windows, and a different password for editing boot parameters or booting into single user mode.

    In Grub1, all I had to do was insert a couple of password lines in menu.lst and, presto!! I got it. I tried to do the same in Grub2, but gave up (http://ubuntuforums.org/showthread.php?t=1369019). Too much hassle.

    @ kwill & Corn Flake,

    I'm sorry it took me so long to respond. I'd been subscribed to this thread for a long time so replies would show up in my in-box but somehow that got goofed up.

    Honestly grub2 should be much better in all but a very few corner situations. I obviously need to rewrite some of this and include recommendations to remedy some grub2 errors.

    Should you decide to give grub2 another try it's quite simple, just look at Appendix #2 in the original post.

    Re: HowTo: Revert from grub2 to Legacy Grub.

    I've been noticing a few too many reports of trouble booting with Natty's grub2 so I'm just posting this to eliminate the need for typing a new post each time. The reports I've been seeing indicate they've already tried recovering grub2 the normal way and also purging and reinstalling grub2 via this guide:

    http://ubuntuforums.org/showthread.php?t=1581099

    I've not been able to reproduce this on my own hardware so I've not yet figured out exactly what's wrong

    Step #1:

    The first thing to do is make sure that Ubuntu will boot so I recommend this disc:

    http://www.bootproblems.com/super-grub2-disk/

    The download link is at the bottom of the page. As it says there, "Super GRUB2 Disk can only be used to boot a broken system, it cannot fix it directly." But I prefer we use only Ubuntu tools and packages to fix Ubuntu's grub2 anyway!

    I've found the "Detect any OS" option to work very reliably. Expect it to be slow, like maybe even a couple of minutes slow booting. Chances are that if that disc won't boot your Ubuntu you have other underlying problems so the rest of this guide is likely worthless to you!

    So, only if the Super GRUB2 Disk gets you booted into Natty proceed with step #2:

    Step #2:

    Please copy-n-paste all commands.

    Code:
    sudo mv /boot/grub /boot/grub_OLD
    Code:
    sudo mkdir /boot/grub
    Code:
    sudo mv /etc/default/grub /etc/default/grub_OLD
    Code:
    sudo rm -R /etc/grub.d
    Some of the following commands will return a message like "not installed, so not removed" or "E: Unable to locate package", that's OK. You'll need to confirm removal of most packages by typing "y". (NOTE: It's also safe to reinstall 'grub-customizer', 'startupmanager', and 'ubuntu-tweak' after you know that grub 2 is restored and booting properly. But it is NOT safe to install the package 'grub'!) When you "purge grub-pc" you'll be asked if you're sure you want to remove all grub files so you'll have to confirm that by using the Tab key to select Yes.

    Code:
    sudo apt-get remove startupmanager
    Code:
    sudo apt-get remove grub-customizer
    Code:
    sudo apt-get remove ubuntu-tweak
    Code:
    sudo apt-get purge grub
    Code:
    sudo apt-get purge grub-pc
    Code:
    sudo apt-get purge grub-common
    Reinstalling grub 2 would hopefully require only one command:

    Code:
    sudo apt-get install grub-pc
    That will likely trigger a process that presents a few debconf windows similar to this:

    Click image for larger version. 

Name:	Screenshot-5.jpg 
Views:	82 
Size:	86.1 KB 
ID:	191329

    Those windows are generally manipulated with the use of the Tab key, arrow keys, and to select/de-select "grub-install" devices you use the spacebar. You must know where you want to install grub!

    If we're lucky that will boot now, if not move on to step #3 after the requisite amount of cursing and once again using the SGD2 disc.

    Step #3: If you're here step #2 failed so we're going to try downgrading to Maverick grub packages, but grub packages are architecture dependent so we must know whether this is a 32bit or 64bit OS! To determine that run the command:

    Code:
    uname -m
    The output i686 = 32bit so if you have a 32bit OS go to step #4!

    The output x86_64 = 64bit so if you have a 64bit OS go to step #5!

    Step #4, for 32bit OS's only:

    Code:
    sudo rm -R /boot/grub
    Code:
    sudo mkdir /boot/grub
    Code:
    sudo rm -R /etc/default/grub
    Code:
    sudo rm -R /etc/grub.d
    Code:
    sudo apt-get purge grub-pc
    Code:
    sudo apt-get purge grub-common
    Code:
    wget http://mirrors.us.kernel.org/ubuntu//pool/main/g/grub2/grub-common_1.98+20100804-5ubuntu3_i386.deb
    Code:
    wget http://mirrors.us.kernel.org/ubuntu//pool/main/g/grub2/grub-pc_1.98+20100804-5ubuntu3_i386.deb
    Code:
    sudo dpkg -i grub-common_1.98+20100804-5ubuntu3_i386.deb
    Code:
    sudo dpkg -i grub-pc_1.98+20100804-5ubuntu3_i386.deb
    Again more debconf windows. When complete reboot. If that works then you'll want to keep those packages from upgrading:

    Code:
    echo grub-common hold | sudo dpkg --set-selections
    Code:
    echo grub-pc hold | sudo dpkg --set-selections
    Step #5, For 64bit OS's only:

    Code:
    sudo rm -R /boot/grub
    Code:
    sudo mkdir /boot/grub
    Code:
    sudo rm -R /etc/default/grub
    Code:
    sudo rm -R /etc/grub.d
    Code:
    sudo apt-get purge grub-pc
    Code:
    sudo apt-get purge grub-common
    Code:
    wget http://mirrors.us.kernel.org/ubuntu//pool/main/g/grub2/grub-common_1.98+20100804-5ubuntu3_amd64.deb
    Code:
    wget http://mirrors.us.kernel.org/ubuntu//pool/main/g/grub2/grub-pc_1.98+20100804-5ubuntu3_amd64.deb
    Code:
    sudo dpkg -i grub-common_1.98+20100804-5ubuntu3_amd64.deb
    Code:
    sudo dpkg -i grub-pc_1.98+20100804-5ubuntu3_amd64.deb
    Again more debconf windows. When complete reboot. If that works then you'll want to keep those packages from upgrading:

    Code:
    echo grub-common hold | sudo dpkg --set-selections
    Code:
    echo grub-pc hold | sudo dpkg --set-selections
    Step #6:

    This is totally optional but I'd personally appreciate it if you'd participate in getting this bug fixed by reporting here:

    https://bugs.launchpad.net/ubuntu/+s...b2/+bug/778059

    I'm wondering if it's hardware related so I think it would be very helpful to collect a hardware profile by running:

    Code:
    sudo lshw > hardwareprofile.txt
    You'll then find a file in your home folder titled "hardwareprofile.txt", so if you'll go to that bug report, make a brief comment, and click on "Add attachment or patch" a new window will open and clicking on "Browse" will allow you to locate that file

    General notes:

    If you want or need to release the "hold" on those grub packages just run:

    Code:
    echo grub-common install | sudo dpkg --set-selections
    Code:
    echo grub-pc install | sudo dpkg --set-selections
    Then of course run:

    Code:
    sudo apt-get update

    Re: HowTo: Revert from grub2 to Legacy Grub.

    Here is my scenario. I install Windows x64 in BIOS/MBR mode. I ran Live Natty to install Natty, but for some reasons, I cannot make it run in BIOS/MBR mode, so my Live USB boots in UEFI/GPT mode. Absolutely no BIOS setting to change from UEFI/BIOS mode, poor BIOS.

    I can install Natty without a problem, but once I reboot, no grub showup and instead boot Windows directly.

    One suggestion was to remove GRUB2 and replace with GRUB1, so I followed this procedure.

    Already finished Natty install and still has not reboot yet. I don't want to reboot since grub does not show up and will just boot Windows instead.
    Normally, if I follow the procedure, the /boot/grub directory points to the Live USB, not the actual Linux partition that I just installed. I tried to change the address of the /boot/grub to something like /media/449b8b9e-027d-4272-9382-dc04fb43661/boot/grub to point to my Linux partition but I got errors.

    QUESTION:
    Is it possible to revert Grub2 to Grub1 while I am at Live USB?
    i5-750/P55-UD3P/HD4850 1GB DDR3/4GB DDR3 A-Data Ubuntu 11.04 x64 Natty/Igelle 1.0.0 DSV /Windows7 x64 (for gaming)

    While running the Live USB can you run the Boot Info Script and post the results as described here:

    http://bootinfoscript.sourceforge.net/

    I'm also curious if your box has a CD/DVD drive. If so the Super GRUB2 Disk is a great tool to have on hand:

    http://www.supergrubdisk.org/super-grub2-disk/

    Note: the download link is at the very bottom of the page. It's not designed to "fix" anything but I've found that it can boot almost anything so it's a nice thing to have while working out boot problems

    Creating a Super GRUB2 bootable USB drive currently requires the use of dd which can be quite complex and risky so I don't recommend that.

    Regardless, the short answer to your question is yes. You can use a chroot from the Live USB to reconfigure grub, including changing from grub 2 to legacy grub. I mentioned it briefly here in post #1, Appendix #1, and included this link:

    http://ubuntuforums.org/showpost.php...2&postcount=10

    But you must be certain to mount the proper partition, etc!!!!!!!!!!!!!

    Finally, I may be unavailable for several hours, possibly 12 to 14 hours, so please be patient

    If you can boot into Windows right now, doing so will cause no harm. In fact my greatest concern is proceeding in a manner that we know will not harm your existing Windows installation.

    I'm also curious, but certainly unsure, if a better way of dealing with this might be to use EasyBCD since Windows boots OK?

    http://neosmart.net/wiki/display/EBC...mentation+Home

    Should you decide to go that way we'd use a shorter version of a chroot to install Ubuntu's grub to it's own root partition and then let EasyBCD handle the boot process

    It's really not incredibly complicated, only confusing when you haven't done it before.

    Re: HowTo: Revert from grub2 to Legacy Grub.

    hi kansasnoob.

    Actually I've done SO MANY things for the past 2 weeks just making my dual boot work. The whole description is in the link below.
    http://ubuntuforums.org/showthread.php?t=1753717

    Starting from post #5, it's all regarding my notebook up to page 6. I think some of your future requests (if ever) are detailed in there already because I've done many experiments.
    Please try to visit that link.

    I've dedicated one hard disk for this, so any request from you I am willing to do, especially if it's a new experiment. I've spent restless nights, nevertheless, I'm still willing to solve the problem. I can reformat the Windows partition anytime, I have a handful of resources - bootable USB sticks, various Linux ISOs, working Dual-boot desktop, external DVD, etc... so don't hesitate if we really need to try an experiment. I just want Dual-boot to work in my notebook.

    I also have tried super grub2, BUT IT DOES NOT BOOT, instead, infinite loop after POST. It is also described in the link above.

    For your request, I will post here again my boot info script result (which is also posted in that thread).

    Current State:
    1. Installed Windows 7 HP x64; confirmed working
    2. Ran Natty Live USB
    3. Installed Natty alongside Windows 7
    4. Reboot. NO GRUB Menu. Proceeds to boot Windows like there is no other OS installed.
    4. Boot at "LUCID LYNX" Live USB (Due to Natty boot script bug)
    5. Result below.

    sdc
    To give you a quick overview, hence:
    1. Notebook is Fujitsu PH521 AMD E-350, 8GB RAM
    2. BIOS: SecureCore Tiano, latest version (1.16)
    3. Absolutely NO menu at BIOS to select UEFI or BIOS boot
    4. OEM installed Win 7 HP x64 in BIOS/MBR mode (already set aside this hard disk)
    5. Fresh Windows installation defaults to BIOS/MBR mode
    6. Natty Live boots in UEFI/GPT mode
    7. Installing Natty alongside Windows went fine. First reboot after install: No GRUB menu, just boots Windows directly.
    8. Installing Natty "alone" is working, BUT no GRUB after post; just boots directly to Ubuntu.

    As for the detailed actions/tests I have done, "please" refer to that thread, my apology. I think it would be easier if we continue on that thread, so this thread is only dedicated to GRUB2 to GRUB1 reversion, just a suggestion.

    At this point, I'll depend on you which one is to try first then this and that. I'm not a Linux expert but I think can follow instructions well, and I've installed dual boot PCs /NBs many times since Hardy.

    If we go the Easy BCD way, so be it. It's almost 2 AM, hopefully we can continue tomorrow. Thanks.
