[EN] fromiso on disk - solved

[Miks]

Hi, I am trying to boot the first Release Candidate of siduction 2012.2 - Riders on the Storm .iso from my hard drive.  I have a new novatech ultrabook with no dvd drive, running mint 13 maya.  I cannot boot using the siduction specific method because I am not running siduction yet.  I have not been able to figure out how to compose the correct stanza so I tried booting with grml.

The stanza grml created is:

menuentry "Grml Rescue System (siduction.iso)" {
        insmod part_msdos
        insmod ext2
        set root='(hd0,msdos1)'
        search --no-floppy --fs-uuid --set=root fddddfd5-90ee-49a7-916e-03a24f98e045
        iso_path="/boot/grml/siduction.iso"
        export iso_path
        kernelopts="   "
        export kernelopts
        loopback loop "/boot/grml/siduction.iso"
        set root=(loop)
        configfile /boot/grub/loopback.cfg
}

this seems to boot to the siduction boot menu ok, but when I boot from that, I get error messages:

error: file not found
error: you need to load the kernel first
Press any key to continue

Pressing any key takes me back to the siduction grub menu.

Any ideas?
Thanks.

Edit:  I have checked the md5sum.

Dont know about greml. Sometime ago I used something like this:

Code: [Select]

menuentry "siduction lxde amd64" {
    set root='(hd0,3)'
    insmod loopback
    loopback loop /isos/siduction-lxde-amd64-20111230.iso
    linux (loop)/boot/vmlinuz0.amd boot=fll
       quiet fromhd=/dev/sda3        
         fromiso=/isos/siduction-lxde-amd64-20111230.iso
          nointro lang=de tz=Europe/Brussels
    initrd (loop)/boot/initrd0.amd
}Two lines:
linux .....
initrd ....

vmlinuz in your iso may have another file name. Look into it!

Short answer:
You could try to boot siduction from usb-stick (read appropriate pages in the manual.

A bit longer answer:
Unfortunately the fromiso boot may or may not work. With the last release there were postings telling one iso starts with a given hardware and does not with an other. And a given hardware, which does not boot one might boot with an other iso (does not boot siduction-kde, but siduction rqt). So to figure out how to boot a given iso on your system could be a very time consuming and frustrating adventure with open end.

Thanks guys.

@ralul:  I moved the iso to a spare partition and adapted your stanza.  It works!
