Booting TC iso from Grub2 menu

[philip_rhoades]

People,

This is the only thing I have been able to find so far on this topic:

http://forum.tinycorelinux.net/index.php/topic,19313.msg119077

and although it works - the netbook only boots to a text mode screen (the same iso boots all the way to a GUI as a VM with qemu-kvm).  I presume I am missing something or there is a step I can take at the text prompt to start X?  Has anyone got a working Grub2 entry that I could try?

Thanks,
Phil.

I guess you're missing the  iso=  boot code.

Code: [Select]

menuentry "Tiny Core - iso" --class core --class gnu-linux --class gnu {
set isofile="CorePlus-5.0.iso"
echo Loading ${isofile} ...
loopback loop (hd0,msdos2)/boot/tce-5.x/boot/${isofile}
echo Loading Kernel ...
linux (loop)/boot/vmlinuz iso=/mnt/sda4/boot/tce-5.x/boot/${isofile} loglevel=3 cde showapps nozswap
echo Loading RAM-Image ...
initrd (loop)/boot/core.gz
echo Booting ...
}
Adopt to your partitioning, file locations / names etc.

Hopefully Misalf's advice solves the issue, otherwise paste your exact grub2 entry. The example you linked needs to be modified for your use case. It contained the boot code desktop=fluxbox, not on the default TC iso. If it can't find the desktop it will boot to text. That example was also for a frugal install, not an iso boot.

People,

No luck - still booting to text - here is my modified version of Misalf's entry (I have the iso in the Fedora "boot" partition):

menuentry "Tiny Core - iso" --class core --class gnu-linux --class gnu {
        insmod gzio
        insmod part_msdos
        insmod ext2
        set root='hd0,msdos1'
        set isofile="CorePlus-current.iso"
        echo Loading ${isofile} ...
        loopback loop /${isofile}
        echo Loading Kernel ...
        linux (loop)/boot/vmlinuz iso=/${isofile} loglevel=3 cde showapps nozswap
        echo Loading RAM-Image ...
        initrd (loop)/boot/core.gz
        echo Booting ...
}

Which was not that different from what I have tried before:

menuentry "Core" {
        insmod gzio
        insmod part_msdos
        insmod ext2
        set root='hd0,msdos1'
        loopback loop /CorePlus-current.iso
#       linux (loop)/boot/vmlinuz isofrom=/CorePlus-current.iso noisapnp
        linux (loop)/boot/vmlinuz nozswap showapps tce=sda4 desktop=fluxbox
        initrd (loop)/boot/core.gz
}

Could it be hardware problems with the netbook? (I wouldn't have thought so - the GUI works with Fedora and xPUD 0.9.2).

Thanks,

Phil.

Any reason you can't install it properly? Instead of an iso file, it would be a couple files in a directory.

[philip_rhoades]

curaga,

Yes, because it turns into a major PITA:

- I don't have a CD drive on the NetBook
- unetbootin doesn't work on the latest Fedora
- there are more, slower, steps than just booting the iso from Grub
- booting from Grub should be able to work - why doesn't it?
.

Try adding the full path in the  iso=  bootcode.

Code: [Select]

menuentry "Tiny Core - iso" --class core --class gnu-linux --class gnu {
set isofile="CorePlus-current.iso"
loopback loop (hd0,msdos1)/${isofile}
linux (loop)/boot/vmlinuz iso=/mnt/sda1/${isofile} cde
initrd (loop)/boot/core.gz
}

Edit: Meaning the path as Tiny Core will see it.

I think " cde " in command line is key, otherwise it will only boot to terminal

- I don't have a CD drive on the NetBook

You could mount the iso and copy the files you need or, alternatively, use the distribution section of the release - usually core.gz or rootfs.gz is all you need to upgrade.

That was already there - see above . .

But I am multi-booting a number of isos and I would still need a Grub2 entry anyway - it is cleaner to just boot on the iso of choice I think but if no one can find a solution then I will have to do the file extraction etc I guess . .

Thanks.

I extracted the files and used this Grub2 entry:

menuentry "Tinycore" {
   set root='hd0,msdos1'
   linux /tinycore/vmlinuz waitusb=5 blacklist=pcspkr nozswap nodhcp cde
   initrd /tinycore/core.gz
}

- but it still only boots to text mode . .

Hi philip_rhoades
Copy the  cde  directory to the root of the drive. Rename it to  tce. Remove the  cde  boot code.

That works! - Thanks . . but does that mean it is not possible to boot the iso from Grub2 to graphics mode?

Specify your window manager as the desktop=* bootcode, example:

Code: [Select]

linux /tinycore/vmlinuz waitusb=5 blacklist=pcspkr nozswap nodhcp cde desktop=fluxbox

I use this and it works for me, all the way up to graphics mode.
