    Read the whole page about multi-booting. Very informative and very helpful. 3rd party boot managers sound pretty promising. Just not sure if you're suppose to install the OS's first then the boot manager or the boot manager first then the OS's.

    Unless you have a bootable device, hard drive or flash drive the boot options will not show it. So if you have not configured any additional boot devices, boot screen may not have anything to show other than default.

    I started configuring multi-boot before most of the scripts appeared. And since I started to learn grub2 after not originally liking it, I found it to be like when you have a hammer everything looks like a nail. I use grub2 for everything.
    So I manually install grub to any device that is not a full install. But any full system install includes grub.

    You can use this procedure for either BIOS or UEFI and for any second device.

    Re: Quad Boot

    Currently testing everything out a virtual machine for now.
    While I'm thinking of it, if I run a bootable disk/program called Kill Disc, will it wipe MBR? If not, how do I wipe MBR. Is there a Linux tool to wipe MBR's? Because I've heard Windows tools don't wipe MBR that have GRUB written to them.

    MBR has two parts. First part is boot code and that you never really have to overwrite as installing a new boot loader for a new system will do that. But second part of MBR is the partition table, rarely would you want to overwrite that.

    I don't want to restore. I want to wipe clean MBR's so that I can start fresh!

    Re: Quad Boot

    Finally, SUCCESS! I've been trying to figure out how to fix this for years!
    How to get only ONE boot loader and not both BCD and GRUB. Finally got it (done in Virtual first, will do for real probably next week or so)!
    Thanks for everyone's help so far! Reading the info on the Multi-bootloader site REALLY helped me to understand things.
    I LOVE Linux, but I've made my decision to use BCD as the Boot Menu/Loader. I have 3 Windows OS's and 1 Linux OS. Plus it seemed to work better.
    Found that (like the multi-boot loader site suggested). It is best to install GRUB to the PBR and not the MBR. I found that was the one of the mistakes I was making all along, was that by default it was overwriting the Windows MBR instead of using it's OWN.

    I can follow these instructions (applies to 1 HDD):

    Above instructions more so apply to when you only have on HDD in the PC. Since I have multiple HDD's, see below....

    Final Resolution:

    a. Plug in one HDD only! Leave the 2nd HDD unplugged from MotherBoard.
    b. Load Linux disc and install, Create ext4 partition (Primary partition), mount point is /
    c. Create swap (Primary partition). Install Linux!
    d. install and open Grub Customizer.
    e. 2nd tab, uncheck options to look for other OS's and show boot menu
    f. 1st tab, refresh, save. Exit. Reboot. Verify that menu is gone. Shutdown.
    g. Unplug Linux HDD from MB and plug in the blank HDD to MB.
    h. Install XP, Win 7, SP1 (for Win7), then Win Serv 08, (in that order).
    (note: after installing XP, immediately disable network adapter!)
    i. Shutdown. Plug both drives into MB.
    j. Boot into BIOS and make Win HDD first boot device.
    k. Boot into Win7, Install Easy BCD
    l. Modify entries (names and order), Save button
    m. Add New Entry, Select Linux tab, choose GRUB2 from drop down menu, name OS, choose the partition where Linux is (this is also where GRUB is), Add.
    n. Review, when done modifying BCD, do NOT write MBR. Just save and exit.
    o. Reboot and test all boot entries!
    p. plug in 3rd HDD and set up an Extended Partition with a Logical Volume. Use this for Personal Data only.

    Answer = Yes.
    I ran Kill Disc on my physical PC. I had to do it in 2 steps to wipe both drives.
    After both HDD's were wiped clean, I booted to Ubuntu Repair Disc and created a Boot Summary.
    When reading the boot summary, it said.....
    => No boot loader is installed in the MBR of /dev/sda.
    => No boot loader is installed in the MBR of /dev/sdb.
