Boot tinycore iso with grub2
« on: June 18, 2012, 11:38:37 PM »
Is the tc4 iso bootable from grub2?

tc2/3 were bootable but it seems something changed with the contents of the iso, boot entry used to look like this:

menuentry "tc" {
 loopback loop /boot/iso/tc2.3.1.iso
 linux (loop)/boot/bzImage --
 initrd (loop)/boot/tinycore.gz
}

Anything special that needs to be done to boot tc4?

HI: Does this setup work for you? Did you try to make it work?
As far as I know "bzImage" from TCL 3.XX changed to "vmlinuz in TCL 4.XX but there are more
differences in going from grub legacy to grub2
Please check our wiki and google. Otherwise please ask me more detailed questions.

You need to use the iso bootcode to find the cde extensions if you boot that way.

(why do people keep trying this? It's an unnecessary layer, emulation, and doesn't even work well half the time... Just install your distros people ;))
The only barriers that can stop you are the ones you create yourself.

some people use multi boot environments and for that they want grub1 or grub2.

Hi beerstein
Yes, but you don't need to boot ISOs to create a multi boot environment, that's what partitions are for.

Changing it from bzimage to vmlinuz and adding in he core.gz line worked!  It now boots, but there still seems to be a problem.  I can't boot to a GUI, I just go straight to the console.  I'm still checking around in the forums and googling but have found no simple answer yet.

I figured it out, the cde directory needed to be in "/" of the USB and specified in the boot options as "cde"

No! rename it tce.

renaming it to tce drops it back to console on boot, even if i change "cde" to "tce" in the boot options.

You need the waitusb=5 boot option.

GRUB* can _not_ boot ISOs.  Don't confuse reading files from an ISO9660 file system image with booting from it.  It can't boot arbitrary ISOs but can boot using files from some ISOs some files from ISOs, presuming it understands how to suitably boot them.

I find this interesting..    Grub2 is a boot loader, it has the ability to read/access ISO's using it's iso9660.mod driver.   it has the capability to of finding an ISO using the findiso command then loop mount the kernel.

I never realized until today that using a loopback config file restores boot menu options seen when booting the cd normally
