Here, we separate the MBR bit, and the actual FS bit. dd if=disk.img of=mbr.img bs=512 count=2047 dd if=disk.img of=fs.img bs=512 skip=2047 5. Because we're on OS X, we need to attach the disk image first, without actually mounting it. There have been a lot of tries to make Grub2 work good with ISOs, but mostly failed. The only combination of commands that seems to work is the following. mount -t proc proc /mnt/proc mount -t sysfs sys /mnt/sys mount -o bind /dev /mnt/dev mount -t devpts pts /mnt/dev/pts/ chroot /mnt
grub-install /dev/sda note: sda is the disk device where you want to install GRUB. You can check it using lsblk -f or using GParted as explained before. 2. Recheck to ensure the that installation has completed without any errors: Older GRUB versions are riddled with nasty bugs. As this probably includes the version from your package management, you should be compiling GRUB from source. As we're compiling for UEFI, you should pass the appropriate flags to configure. An example invocation might look something like this:
Double check that you put the brace on the same line of "menuentry". It can't be on a new line. This is not C. Some versions of GRUB 2 like to put Multiboot modules in relatively high physical memory addresses, in contrast to GRUB-legacy which loaded them into low memory. Be careful when making your kernel work with GRUB 2 that it is not making any assumptions about where the Multiboot modules will appear. mount /dev/[partition used for Manjaro system] /mnt In this instance, as the Manjaro system partition is /dev/sda3, this will be mounted using the following command: set timeout=15 set default=0 # Set the default menu entry menuentry "OS Name" { multiboot /boot/kernel-file # The multiboot command replaces the kernel command boot } That's basically it. Copy these files to a disk image, pop it in an emulator, and you're done!
As mentioned, Ubuntu 14.04 is installed on my old/legacy PC, with option acpi=off. In my legacy Fujitsu M2010 Netbook, it display in 800x600 only GNU GRUB is a Multiboot boot loader. It was derived from GRUB, the GRand Unified Bootloader, which was originally designed and implemented by Erich Stefan Boleyn Since we have a 80MB disk, the CHS values are 78, 32 and 63 respectively. 3. Fire up FDISK (or your tool of choice) -- I'm using the OS X version here, so commands may differ. The concept is essentially identical.

Nastavení Grub2 If you are still unsure, then you can also use an application called gparted, which should be in Menu > System > GPartEd. This will provide a simple visual illustration of the partitions on your hard drive(s). If a separate partition for the GRUB exists, it will be marked as 'bootable', and should only be about 100MB in size. Important: To build GRUB 2 so that it can produce a bootloader for your output target you need to have a compiler for that target. So for example, if you want a bootloader for i386-elf (as suggested in the bare bones) you'll need Binutils + a compiler for that target. This is required on OS X because the built-in LLVM doesn't know how to make i386-elf binaries. So you can either build a cross-compiler or create an OS-specific toolchain (recommended) for your target platform. You will need the cross-versions of GCC, objcopy, strip, nm and ranlib in step 4. 1. Ensure that you are using the Root account, which is identified by a hash ('#') at the beginning of the command line, rather than a dollar ('$'). To switch to Root, enter the command:
3. Invoke grub-install (on some systems this command is called grub2-install, located under /usr/sbin or /usr/local/sbin) If you plan to use the grub boot loader, when partitioning the disk you have to make the root partition smaller than 512Mb, and formatted as FFSv1 with 8k block/1k fragments. If the partition is larger than.. dd if=/dev/zero of=disk.img count=163840 bs=512 2. For an explaination on calculating the CHS values from the LBA / size see Floppy_Disk_Controller#CHS
The file name /etc/grub2.cfg is a symbolic link to the grub.cfg file, whose location is architecture dependent. It is better to use absolute paths when accessing to a file, as in the example above.. GRUB version 2 started its life as the PUPA (note the pun) research project and was rewritten from the ground up. Since then GRUB 2 (actually at time of update 1.97) has grown more stable and even hobby operating systems use of the new bootloader instead of GRUB Legacy.

If you set it as “1”, the second OS will boot, and so on.sudo grub-install --root-directory=/mnt --no-floppy --modules="normal part_msdos ext2 multiboot biosdev" /dev/loop0 If you mistyped /dev/loop1 (pointing on your partition) instead of /dev/loop0 (pointing on your MBR), you would receive message that grub-install can't use 'embedding' (because there's no space for it) and that it would like to use 'block lists', which are not recomended. This information might not be applicable to Linux users, who will most probably want to use a loopback device. This is for developers on OS X, which doesn't have a loopback device and has a finicky image mounter.
