Hi, I've created an image (in various formats: ext2/iso/tar) with buildroot



11/2011. Until now I've used unetbootinet to create a bootable usb pen drive for testing in the target machine (i386).

Now I want put the image to my hard disk, and boot from that.



How can I put the image into the hard drive and make it bootable?



Thanks a lot!

You'll need a bootloader of some sort (grub, lilo, etc.), and of course an appropriate kernel. Beyond that, just create a normal ext2/3/4 filesystem in a normal partition, and make sure the boot loader is in a partition marked bootable (or the MBR).

There really shouldn't be that much different between a USB drive and a hard disk, beyond getting the BIOS to look at the right device (which I'd imagine would be harder with the USB drive than the hard disk).

I've discovered that the version of grub installed by buildroot has a little bug (actually is a patch that has some trouble) and when I try to install with Qemu and the key usb passed with -hda option I've got a segmentation fault on setup (hd0). Now I'm trying with lilo.
