    More direct is prof. Jane Plant CBE in her book "The No-Dairy Breast Cancer Prevention Program". In her case multiple surgeries, radiations, chemo's were not working and she had months to go. Changed her life style, that was 17 years ago and now she's doing fine. Importantly, she's found that men's prostate cancer is also susceptible to the same things and is also resposive to life style changes.

    One of the considerations is cow's milk is intended to grow calves into steers as fast as possible. Many things in cow's milk enable fast growing cells to grow faster....such as calves or human cancer cells...

    Our son after a year of poor sleep, waking up after a couple hours, etc. is now doing better granted his condition is much different than yours- but does involve the brain.

    We find the standard medical practices are drugs, surgery, radiation, etc. with little knowledge of life style. Much more is in Cornell nutritional bioligist prof. T. Colin Campbell's book "The China Study". A specialty of his is liver cancer which is also very responsive to life style.

    All 3 books are available from Amazon and bookstores. All three of these authors are scientists so they do get into detail of studies and evidence and how and why as well as what to do.

    a) proposed by yann
    HTML Code:
    Please try creating a little boot partition at the start of your Quantal disk ( sdb). See https://help.ubuntu.com/community/BootPartition
    b) proposed by herman
    wouldn't it be better if they fixed the existing grub ? Or reverted to one that actually works ?
    if it ain't broke you haven't tweaked it enough

    Some time ago I'd noticed a true decline in my already limited mental abilities so the docs got busy.

    The first thing they found wrong was a partially collapsed arterial stent. Getting that fixed was a piece of cake and I felt much better

    But the docs were very thorough and they also found some new melanomas. I know I'm not going to live forever so I don't care a whole lot, but the treatments are making me so sick I sometimes wish I'd just die in my sleep

    I wish I could sleep more than two hours at a time w/o vomiting or crapping the bed
    Fingers are crossed and wishing You all the best!

    Wink Re: New grub NOT mega-multi-boot freindly

    Makes no sense to me, a tester/user. For example I just tried:

    #!/bin/sh
    exec tail -n +3 $0
    # This file provides an easy way to add custom menu entries. Simply type the
    # menu entries you want to add after this comment. Be careful not to change
    # the 'exec tail' line above.
    menuentry "QuantalB1 on sda1" {
    set root=(hd0,1)
    linux /vmlinuz root=/dev/sda1 ro quiet
    initrd /initrd.img
    }

    How simple is that.

    Make the file executable, example
    sudo chmod +x custom

    If you name it 06_custom
    sudo cp 06_custom /etc/grub.d

    it will show up in the grub boot list as the first entry, the default.

    If you name it 40_custom
    sudo cp 40_custom /etc/grub.d

    it will show up at the end of the list which is what I usually do.

    After copying do
    sudo update-grub

    As usual, expect some oops and fixes. Grub2 does some wierd things like mix up /dev/sda1 and /dev/sdb1 vs. hd(0,1) and hd(1,1)

    I cannot tell the difference between boot times or the resulting booted ubuntu with either the simple or the hugely complex mess that grub2 spills out.

    ?

    Now do note I'm using the /vmlinuz and /initrd.img links to /boot.

    If instead you use

    /boot/vmlinuz-3.5.0-14-generic
    /boot/initrd.img-3.5.0-14-generic

    you can select different kernels example if you are using some ppa's but you have to change the _custom file whenever there's a change in /boot. Seems to me in the old days grub used to enable booting the different kernels in the boot list, now grub2 doesn't do that I've seen.

    Colin works on it right now, you can follow via the report. But grub is way too sensible of extern packages version. So my choice.

    @Jerry

    if you want really doing test, its with the real package, not with added workarounds, except if they are going to upstream, which i doubt a little.

    Re: New grub NOT mega-multi-boot freindly

    (Begin rant.)

    I almost feel like putting a big, fat "Bite Me!" on the Launchpad bug for Colin.

    I know this stuff isn't easy. I know he's working on it. But c'mon.

    After updating both Quantal installs (Ubuntu and Xubuntu) on my multi-disk multi-boot machine, to go back to my primary and update GRUB and find the monstrously verbose and incomprehensible entries, I was miffed.

    When I shut down and tried to boot into my primary the next time and got the "alloc magic" error (I think the alloc magic error is generated because the insanely verbose entries for the other Ubuntu selections overflow the buffer. Maybe if that is fixed, I can get into Precise and just update GRUB.) and then had to restart, change the boot order in BIOS and use the GRUB from my Quantal install to get into Precise on my primary disk, I was somewhat less than happy. It would take me more time than it is worth to sort out GRUB on my primary disk since I'll be going to Quantal on it soon enough, so I'll just go with what I have and switch the boot order back when I've installed Quantal on that disk.

    We expect stuff to go wrong from time to time in testing. But for something like this to cause problems with getting into my primary install in a multiboot situation is really inexecusable. Dual and multibooting is so common as to be almost a certainty for many users. This is something that should have been spotted.

    (End of rant. And my genuine thanks to Colin for working on it - which is why I won't actually rant in the bug report.)

    grub has been very good at finding and adding all of my installs regardless of the grub version the install used for atleast the last year , infact I commented on this back during the precise cycle that I was happyt that it was working at last . So this represents a definite regression .Glad to hear colin is working on it , in the meantime I'll just switch 1st boot drives in bios and let another distro handle the booting .

    I mostly use the real package as is & some testing of Unity for bugs, since I'm no Unity expert on all the frills and functions for general utility I switch desktops. That still tests lots of Ubuntu things like kernel & ubiquity & gedit (has a launchpad bug right now) and "Files" and Firefox (has a launchpad bug) & Xorg & hidden wireless (has a launchpad bug) & on and on.

    I've been using the Grub2 mess as is except some special purpose activity. Somebody asked why Grub2 is so complex so I gave a working example which I use on occasion, showing Ubuntu 12.10 booted just fine with simple human readable four line syntax.

    Perhaps you prefer as follows. With a quick glance, what partition is being booted? Hint: I have 12, a variety of ubuntu levels, a fairly small setup.

    /boot/grub/grub.cfg
    ......lots of prolog, now for what I think is the default boot image:
    function gfxmode {
    set gfxpayload="${1}"
    if [ "${1}" = "keep" ]; then
    set vt_handoff=vt.handoff=7
    else
    set vt_handoff=
    fi
    }
    if [ "${recordfail}" != 1 ]; then
    if [ -e ${prefix}/gfxblacklist.txt ]; then
    if hwmatch ${prefix}/gfxblacklist.txt 3; then
    if [ ${match} = 0 ]; then
    set linux_gfx_mode=keep
    else
    set linux_gfx_mode=text
    fi
    else
    set linux_gfx_mode=text
    fi
    else
    set linux_gfx_mode=keep
    fi
    else
    set linux_gfx_mode=text
    fi
    export linux_gfx_mode
    if [ "${linux_gfx_mode}" != "text" ]; then load_video; fi
    menuentry 'Ubuntu' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-f3f05f04-bafa-4e54-a52d-aab85819263b' {
    recordfail
    gfxmode $linux_gfx_mode
    insmod gzio
    insmod part_msdos
    insmod ext2
    set root='hd1,msdos8'
    if [ x$feature_platform_search_hint = xy ]; then
    search --no-floppy --fs-uuid --set=root --hint-bios=hd1,msdos8 --hint-efi=hd1,msdos8 --hint-baremetal=ahci1,msdos8 f3f05f04-bafa-4e54-a52d-aab85819263b
    else
    search --no-floppy --fs-uuid --set=root f3f05f04-bafa-4e54-a52d-aab85819263b
    fi
    linux /boot/vmlinuz-3.5.0-14-generic root=UUID=f3f05f04-bafa-4e54-a52d-aab85819263b ro quiet splash $vt_handoff
    initrd /boot/initrd.img-3.5.0-14-generic
    }

    BTW I worked 42 years in IBM main frame computer development where speed and efficiency are worth real $$ price/performance. Tends to color my outlook.

    Anyone else notice this?
    Yes, same here. I didn't install GRUB version 2.0 to MBR yet. I'm still using GRUB 1.99 and I have the same issue (LONG names/entries).
