You have to do the partitioning and then install FreeBSD's boot manager by hand. It /does /work; I ran into the same thing with my Lenovo X220 and was able to manually install it, which works fine to dual-boot between Windows and FreeBSD-11. I had to do it manually because the installer detected that the X220 was UEFI capable and insisted on GPT-partitioning the disk, which is incompatible with dual-boot and the existing MBR-partitioned Windows installation.Hi there,I try to install amd64 FreeBSD 11.1 in dual-boot with Windows 7 on an MBR partitioned disk and I can't make it bootable. My Windows 7 uses its standard MBR partitioning scheme (1. 100MB System Reserved Partition; 2 - 127GB disk C partition) and there is about 112GB of free unallocated disk space that I want to use to install FreeBSD on it. As an installation media I use the FreeBSD-11.1-RELEASE-amd64-mini-memstick.img flashed on a USB drive. During the installation, if I choose to use Guided Partitioning Tool and automatic partitioning of the free space, I get a pop-up message that says: ====== The existing partition scheme on this disk (MBR) is not bootable on this platform. To install FreeBSD, it must be repartitioned. This will destroy all data on the disk. Are you sure you want to proceed? [Yes] [No] ====== If instead of the Guided Partitioning Tool I choose to partition the disk manually I get a similar message as a warning and the installation process continues without an error, but the installed FreeBSD system is not bootable. Installing boot0 manually (boot0cfg -Bv /dev/ada0) doesn't fix it. The boot0 boot loader is able to boot Windows but it's unable to start the FreeBSD boot process. It only prints hash symbols when I press F3 (the FreeBSD slice/MBR partition number). I consider this as a critical bug. But maybe there is some workaround that allows me to install the FreeBSD 11.1 as a second OS without repartitioning the entire disk? My hardware is an Intel Core i7 4790 3.6GHz based machine with 16GB RAM. The ada0 disk is 238GB SanDisk SD8SBAT256G1122 (SSD).
You want the partition layout to look like this: $ gpart show => 63 500118129 ada0 MBR (238G) 63 4208967 1 ntfs (2.0G) 4209030 307481727 2 ntfs (147G) 311690757 3 - free - (1.5K) 311690760 165675008 3 freebsd [active] (79G) 477365768 808957 - free - (395M) 478174725 21928725 4 ntfs (10G) 500103450 14742 - free - (7.2M) => 0 165675008 ada0s3 BSD (79G) 0 8388608 1 freebsd-ufs (4.0G) 8388608 136314880 2 freebsd-ufs (65G) 144703488 20971519 4 freebsd-swap (10G) 165675007 1 - free - (512B)MBR has only four partitions; the "standard" Windows (7+) install uses /three. /The "boot"/repair area, the main partition and, on most machines, a "recovery" partition. That usually leaves partition 3 free which is where I stuck FreeBSD. Note that you must then set up slices on Partition 3 (e.g. root/usr/swap) as usual.
