Solved How to boot FreeBSD-10.1-RELEASE-amd64-dvd1.iso via grub2 from USB?

NO.1 I love FreeBSD

I have a USB stick with a grub2 bootloader installed. Great tool when you want boot an iso without burning CD's.

I now want to boot the FreeBSD installer from the stick and have FreeBSD-10.1-RELEASE-amd64-dvd1.iso on an FAT32 partition of the stick. I chose to use FreeBSD-10.1-RELEASE-amd64-dvd1.iso because I figured FreeBSD memstick.iso would install the FreeBSD bootloader on the stick and remove grub2. My USB already can be boot (Gentoo+Debian+Kali+WinXP+Win7+ghost+DM+PQ) very well.

HOW to write menu entry in grub.cfg for FreeBSD(FreeBSD-10.1-RELEASE-amd64-dvd1.iso)?

Anyone help me? Thanks!

FreeBSD is my best love, my USB stick can't miss it.

The best starting point and least redoing work that's already been done would be borrowing what you need from how PCBSD/TrueOS build their grub.cfg.

What exactly have you tried? Get really concrete please, for example by posting your current grub.cfg.

It looks like in Thread 19701 they described some layout changes in FreeBSD 9.0+ ISOs that have made the steps not work anymore. The mfsBSD ISOs, a lightweight FreeBSD image that runs in memory, may come to the rescue here... have you seen Thread 46480? That cover a recent example that will hopefully work for you with the mfsBSD ISO which you can get from one of the FreeBSD devs web site here: http://mfsbsd.vx.sk/.
