[CoLoCo] running LiveCD from HD help

[Kevin Fries]

There is another way of doing it, but boy is that ever complicated.  It involved running Xserver-Xephyr to create a second X server running nested inside your main X server.  Then you need to run the CD in a separate process, and bind that instance to Xephyr.  There, no VM.  But, that being said, if all you want is a solution that works to try this software, I would just use the simplicity of a Virtual Machine.

Well, i just wanted to try it out like i was booting from it burned on a cd, but really didn't want to use a VM. But, maybe that would just be easier. It just bugs me that i almost got it to boot this way. Some people call it the "poor man's install" even though most don't install with it.

OK, you have me confused, so you are probably confusing others also.



If you are trying to run the CD like it would in the drive, complete with a GUI desktop, use something like VM-Ware or Sun's VirtualBox.  Load the CD in the VM and no hard drive.  Start the VM, and it will run in a window on your machine.



If you simply want a command line, you can always just chroot into the directory where you extracted the files.



On the other hand, if you are trying to install onto your hard drive:



… and you are trying to replace your current OS, you need to add the kernel and boot info to your existing /boot directory, then add a new grub menu listing to load that kernel.  Most CDs that I have ever used will then start the install.



… and you are trying to install into a separate directory, I would just chroot into that directory, then manually start the text based installer.



Hope I helped in some way

Since i didn't have a dvd on hand to try out the gOS space thing, i decided i would try to run it from my hard drive instead. I've gotten close several times, but I am having some problems.

I started based of this first:

http://www.neowin.net/forum/lofiversion/index.php/t305843.html

But, that is for noppix, and isn't quite perfect. So, i wen't to this, which was closer, but still not perfect. http://www.linuxquestions.org/questions/ubuntu-63/fluxbuntu-poor-mans-install-is-it-possible-531616/

I've gotten the live-dvd extracted to /mnt/hda4/gOS

and this is the current grub initiation i'm using, but it gives me a busybox and a initramfs prompt instead of booting up.

title gOS Live-CD from HD

root (hd0,0)
kernel /mnt/hda4/gOS/casper/vmlinuz ramdisk_size=1048576 root=/dev/ram rw quiet splash
initrd /mnt/hda4/gOS/casper/initrd.gz
savedefault
boot



any suggestions would help. Thanks.
