Boot in use of ISO file of live cd!

Sorry for that I can’t type in Korean right now…
I have to type in Konglish…

I finded the way to boot by not cd/usb but iso file in hard disk.

Add boot menu like below.
(Modify your /boot/grub/grub.cfg)

menuentry "Boot by Live CD ISO File" {
loopback loop color=#BF0000:1q790gy8/cd.iso[/color:1q790gy8]
linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=[color=#BF0000:1q790gy8]/cd.iso[/color:1q790gy8] noprompt
initrd (loop)/casper/initrd.lz
}

Red path can be modified according to your iso file location, but don’t edit other lines.

Good luck!

Attention
In installation, don’t format the partition in which ISO file is!

이제는 한글을 쓸 수 있네요. 휴.

만약 이 방법을 통하여 부팅 후 설치 과정 중에 /isodevice를 언마운트 할 수 없다는 에러가 뜨신다면
설치를 취소하시고 ctr + alt + f1 콘솔로 나와서

[code:pbpl2ggj]umount -l /isodevice[/code:pbpl2ggj]
그리고 alt + f7 다시 콘솔에서 빠져나와 설치 시작하시면 됩니다.
