Since this is an end user support question, rather than a patch or discussion about developing grub, it should be posted to help-g...@gnu.org rather than grub-devel. I have CC'd helo-grub. In your replies, please include help-grub and *remove* grub-devel from any further replies. This problem is also actually more Fedora specific than grub related, as explained below. > > The contents of /dev/sda6 is: > > dr-xr-xr-x 3 root root 4096 May 22 05:03 EFI > dr-xr-xr-x 2 root root 4096 May 22 05:05 LiveOS > dr-xr-xr-x 2 root root 4096 May 22 05:03 isolinux > drwx------ 2 root root 16384 Nov 2 06:08 lost+found > -r--r--r-- 1 root root 2460 May 22 05:04 Fedora-Legal-README.txt > -rw-r----- 1 qemu qemu 1007681536 Oct 7 20:14 > Fedora-Live-Xfce-x86_64-22-3.iso > -r--r--r-- 1 root root 1063 May 22 05:04 LICENSE > > > I have made a little progress but I still can't get a boot - here is the > current state of the relevant section of my grub2.cfg (I have been trying > various changes): > > menuentry "Fedora 22 XFCE ISO Boot (x86_64 bit)" { > insmod part_gpt > set isoname="Fedora-Live-Xfce-x86_64-22-3" > echo $isoname > set isofile="${isoname}.iso" > echo $isofile > loopback loop (hd0,gpt6)/$isofile > echo $loop > linux (loop)/isolinux/vmlinuz0 root=live:CDLABEL=${isoname} > rootfstype=auto ro rd.live.image rd.luks=0 rd.md=0 rd.dm=0 > iso-scan/filename=${isofile} iso-scan/filename= is a kernel parameter that Fedora does not support, as Fedora does not support loop booting (booting from the iso file on a filesystem rather than burned to a DVD or extracted to a hard drive). Please file a bug report against Fedora asking them to add such support, or extract the iso (which you have also done already), or use a distribution that supports loop booting such as Ubuntu. For instructions on loop booting an Ubuntu iso (or any other iso which ships with a loopback.cfg) please see http://www.supergrubdisk.org/wiki/Loopback.cfg#How_do_you_use_a_loopback.cfg_to_boot_an_iso.3F . > initrd (loop)/isolinux/initrd0.img > } > > During the attempted boot I see the first two "echo"s but then get messages > that "linux" and "initrd" commands do not exist . . is it something simple I > am missing? This is a Fedora specific problem, with upstream grub you would not have this problem. I am not very familiar with Fedora's secure boot setup, but I suspect that is the reason that the "linux" and "initrd" commands are not available, and that instead you need to use "linuxefi" and "initrdefi". > > Thanks, > > Phil. > -- > Philip Rhoades > > PO Box 896 > Cowra NSW 2794 > Australia > E-mail: p...@pricom.com.au > > _______________________________________________ > Grub-devel mailing list > Grub-devel@gnu.org > https://lists.gnu.org/mailman/listinfo/grub-devel _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
