Grub2 is a bit of a change. The advantage, IMO, is that grub 2 works much better out of the box and the need for manual configuration is much less. The disadvantage is that it is more complex to manually configure, as you found out, and the syntax has changed. The best single source of information on gurb2, IMO, is still: https://help.ubuntu.com/community/Grub2 although that page does not cover all the options (insmod). grub2 is modular, somewhat like the kernel, you can see all the modules in the /boot/grub directory. You use or load them with insmod. To be honest, I think you are doing this the hard way ;) What is it you do not like about the defaults such that you are chainloading ? I personally also highly suggest you post documentation of this sort on the Fedora wiki rather then a mailing list as this seems more documentation rather then a question. ----- Original Message ----- From: "Tom Horsley" <horsley1953@xxxxxxxxx> To: "Fedora Test List" <test@xxxxxxxxxxxxxxxxxxxxxxx> Sent: Friday, April 20, 2012 11:14:28 PM Subject: Grubs really aren't very attractive... I've just spend most of an evening getting a stand alone GRUB2 partition to work (if you can call it that) and I consider myself lucky I managed that much :-). Here's the fascinating fruit of my labors - a grub.cfg that can multi boot fedora 16, fedora 17, and memtest: set default="0" set timeout=10 menuentry "Boot Fedora 16" { set root='hd0,msdos3' chainloader +1 } menuentry "Boot Fedora 17" { insmod gzio insmod part_msdos insmod ext2 set root='hd0,msdos5' multiboot /boot/grub2/i386-pc/core.img } menuentry "Boot Memtest" { insmod gzio insmod part_msdos insmod ext2 set root='hd0,msdos1' linux16 /memtest/memtest86+-4.20.bin } This is using the grub2 that ships with fedora 17 Beta. Note that the word "kernel" doesn't appear anywhere. With the latest grub2 improvements, you apparently must tell it what kind of kernel, so there are different commands like linux, linux16, multiboot, etc. Also note that fedora 16 doesn't use multiboot. It simply refused to work on the fedora 16 partition. Apparently the f16 grub2 isn't compatible with the multiboot standard they run on and on about in the info file without ever actually managing to say what the heck it is :-). So I'm still chainloading to boot fedora 16. I previously had grub1 installed in the MBR. To get grub2 (after various failed attempts), the magic seemed to be: rsync -a /boot/grub2/ /mainboot/grub2/ That gets all the modules and wot-not copied into the /mainboot partition I'm using as a stand alone grub. I don't know if the following is actually necessary, but it didn't work right till I did it this way. (The disk is sdb at this point because sda was the live USB stick I needed to use after breaking the boot with previous install attempts :-). mv /boot /origboot mv /mainboot /boot grub2-install /dev/sdb1 mv /boot /mainboot mv /origboot /boot edit /mainboot/grub2/device.map and fix the sdb names to say sda (which is what the disk will be when booting without the USB stick). And that's how I got a stand alone grub2 partition fixed up to boot multiple versions of linux. Simple :-). -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
