    Quad Boot

    Want to turn my Triple Boot into a Quad Boot. I will definitely start with a clean slate and re-install all OS's and format all partitions. What order should I install?....

    Windows XP
    Windows 7 Professional (64 bit)
    Windows Server 2008
    Linux, Ubuntu 12.04 (Lucid Lynx)


    (Ya ya, I know. I should update to a newer version of Ubuntu. I like this one though.)
    What do you think, what order? Thanks.

    Re: Quad Boot

    Hello!

    I'd get the partitions in order first, and then maybe go to the Windows 7 forums to get advice on how to do the Windows stuff.

    Then install Ubuntu (take care with your partitions) last.

    Re: Quad Boot

    Install all Windows in primary partitions and use 4th primary as the extended for Ubuntu, swap and shared data NTFS partition.
    Why install XP? It may be dangerous to use on Internet.

    To get each MS to have its own boot loader make a second primary NTFS partition and set its boot flag on, then install the 2nd product in it. Multibooters, Pictures here worth 1000+ words - Vista but all Windows with BIOS/MBR

    Re: Quad Boot

    Need XP for certain application support. Applications that are hardware reliant and do not work in a virtual machine.
    I do not plan on using XP on the internet. I plan on disabling all internet/network connections within the XP OS.

    I only want one boot loader. But as of right now (on my triple boot) I have two boot loaders. Which is unfortunate. I have BCD (Boot Configuration Data) from Windows 7 and I have GRUB2. Wish I could use one or the other only, preferably a Linux loader. I've even tried using LILO or some other Linux loader. Unsuccessful.

    What do you mean
    "4th primary as the extended for Ubuntu, swap and shared data NTFS partition." ???
    Primary or Extended partition? Which one, only can be one or the other. And if I have a Swap and Data NTFS partition, do they need to be Extended Partitions?
    There is only 4 Primary partitions available, right? Or is that 4 Primary per HDD?

    Re: Quad Boot

    It is 4 primary partitions per hard drive. The extended partition is a primary partition that is just a container for as many logical partitions as you want to add or have space available.

    Windows only boots from one primary NTFS partition with the boot flag from the drive set as bootable in BIOS. And every additional install of Windows moves its boot files into that one primary and has no boot files of its own, so grub will not see those installs.
    See link to mulltiboot site above for details.

    If the other installs of Window are in primary partitions you can move boot flag and repair them to include boot files. Then grub can directly boot them. If Windows is in a logical partition you will not be able to boot it from grub as you cannot add the boot files or do the repair to add the boot file.

    Re: Quad Boot

    Ok, just looked over my own notes of my triple boot and from what I read about Windows. They said oldest Windows OS first. So, the order I have it in at the top is correct.
    And according to my notes when I did my triple boot, I actually had to unplug the HDD with Linux on it so BCD (100 MB partition) would not overwrite it. Then plug it back in after install of Win7. Then I went and made the HDD with Linux on it the Primary Boot Device.
    Since I have 3 Win OS's and 1 Linux OS, maybe I should use BCD instead of GRUB. Not sure what your thoughts are. Whatever is easier to edit!
    I have 3 separate HDD's. So making all Primary shouldn't be an issue (except Swap should be extended of course).

    Re: Quad Boot

    I do not know Windows BCD, my last Windows was XP.
    With multiple drives you want to keep the Windows boot loader in the MBR of the Windows drive and grub in the MBR of the Ubuntu drive.
    Again if you repair the Windows installs by first moving boot flag and run Windows repairs then that partition will directly boot from Windows MBR. But then grub can find the boot files and let you boot each Windows install directly.

    Did you review the multiboot site, it explains Windows booting and MBR and PBR booting in general.

    Re: Quad Boot

    Ok, yes I read them both. I don't fully understand how to remove a boot flag. It sounds complicated with gparted? I don't understand how Linux labels drives (sda, sdb, sda2, etc.).
    Can't I just go into BIOS and tell it which HDD's are not bootable?
    I think it'd be BEST if I test this ALL out in a Virtual Machine first before doing it for real!

    Re: Quad Boot

    With gparted you just right click on a partition and set the boot flag. You can only have one boot flag per hard drive and for Windows it must be a primary partition.
    In Windows you set boot flag with the set active command, as Windows calls it the active partition or the one you boot from.

    Drives are sda, sdb, sdc etc, partitions are a number or sda1, sda2. No confusion if in Windows a "d" drive is really second partition in the first drive like sda2 or a partition on a second drive like sdb1.

    Re: Quad Boot

    I'm kinda screwed now and need help.
    I am trying to change the boot flag from Linux. Built in utility called Disk Utility. When I clicked the 100 MB partition and choose "bootable" to set the boot flag and said "Apply". Now it just sits there Applying, spinning the wheels. Won't finish. I've waited several minutes.
    Then I went to set the Linux partition to non-bootable to get rid of the boot flag from there. Now that one just sits there too.
    I'm afraid to reboot, since it hasn't finished applying the settings. I've logged out and back in to see if the app would reset, but it's still just spinning wheels.

    Should I have UNflagged the one partition, before setting the flag for another?
    Should I have put the boot flag on the 100 MB partition or on the Windows partition itself?
    Afraid to reboot. How do I fix to set a boot flag?!?!?
