Grub - boot debian iso file from ntfs partition and install it
Solution 1
You need download initrd.gz
from hd-media directory and put it in the same directory with the image file and give it a suitable name.
For example my grub.cfg
menuentry 'Debian Jessie (stable) graphical expert' {
set isofile='/iso/debian-8.3.0-amd64-lxde-CD-1.iso'
set initrdfile='/iso/gtk/debian-8.3.0-amd64-lxde-CD-1.initrd.gz'
loopback loop $isofile
linux (loop)/install.amd/vmlinuz findiso=$isofile dekstop=lxde priority=low gfxpayload=1024x768x32
initrd $initrdfile
}
I find solution in Reddit and here
Solution 2
You must download the hd-media/vmlinuz and hd-media/initrd.gz and use them as the Linux kernel and initial ramdisk respectively. You can't use the vmlinuz and initrd.gz inside the Debian ISO image. The Debian ISO image is the CD the installer ask for.

I have problem installing debian directly from hard drive. Say, i have a logical partition
/dev/sda5
and there is debian DVD iso file located in(hd0,5)/iso/debian-8.0.0-amd64-DVD-1.iso
withinitrd
file there too. Then I created grub menu entry with this:menuentry "Debian Jessie (stable)" { set isofile='/iso/debian-8.0.0-amd64-DVD-1.iso' set initrdfile='/iso/debian-8.0.0-hdd.initrd.gz' loopback loop (hd0,5)$isofile linux (loop)/install.amd/vmlinuz iso-scan/ask_second_pass=true iso-scan/filename=$isofile initrd (hd0,5)$initrdfile }
Booting is successful. But, when come to searching debian CD it fails. The iso file cannot be found by installer. If I use USB drive, every thing goes fine. In USB, I put debian DVD iso in `/boot/iso/debian-8.0.0-amd64-DVD-1.iso'. And the menuentry look like this:
menuentry 'Debian Jessie (stable)' { set isofile='/boot/iso/debian-8.0.0-amd64-DVD-1.iso' set initrdfile='/boot/iso/debian-8.0.0-amd64-DVD-1.hdd.initrd.gz' loopback loop $isofile linux (loop)/install.amd/vmlinuz iso-scan/ask_second_pass=true iso-scan/filename=$isofile initrd $initrdfile }
My
/dev/sda5
is formatted inNTFS
and my USB drive is formatted inFAT32
. So, I guess the problem is because of filesystem format. And if it is, how can I boot debian iso file properly from NTFS partition?Update
The NTFS partiton is logical partition. Is it causeing problem too?

Vincent Nivoliers about 9 yearsFrom this related thread in ubuntu forums, you may have to insert additional modules in the menuentry, such as
insmod ntfs
