All is in my question.
I have installed the Boot Loader in FreeBSD which is installed on a separate HD, and Fedora Grub launchs my OS's.
My configuration :
- sda : Fedora17 (first HD and MBR)
- sdb : XP/Slackware
- sdc : FreeBSD9.1
I have tried many different 'menuentry' in Fedora Grub2, nothing is working.
But I can boot FreeBSD after changing HD order in BIOS, and I boot directly in The HD on the Boot Loader.
I need a menuentry working, if it exists !? I saw some bugs about it, with Fedora17...
I know that it is possible with Debian, Ubuntu, for example.
Thank you for your answers, if you got them !
