[SOLVED] Cannot boot Hiren's Boot from an ISO on ext3?

Hi,

I want to boot Hiren's Boot CD from an ISO file on HDD. Under Windows, I put the ISO file into C: drive, use grub4dos and configure something like this:

Code:

title Hiren's Boot 9.8 map chainloader
find --set-root /hiren98.iso
map (hd0,0)/hiren98.iso (0xff) || map --mem (hd0,0)/hiren98.iso (0xff)
map --hook
chainloader (0xff)
boot

and it works fine.

But under Gentoo, put the ISO file into / and try 2 different ways

Code:

title Hiren's Boot 9.8 kernel initrd
root (hd0,0)
kernel /boot/grub/HBCD/memdisk quiet
initrd /boot/grub/HBCD/boot.gz /s

(tried to put the HBCD folder on both of / and /boot/grub/)

Code:

title Hiren's Boot 9.8 map chainloader
find --set-root /hiren98.iso
map (hd0,0)/hiren98.iso (0xff) || map --mem (hd0,0)/hiren98.iso (0xff)
map --hook
chainloader (0xff)
boot

and none of them works. With the first, I can boot into interactive menu, but whenever I choose an application (such as Acronis Disk Director Suite, Ghost, ...), I got the error:

Quote:

"HBCD folder not found! Do you want to try again?"

With the second, it gives me the "Error 15: file not found" at the `find` command, although I can found it without --set-root:

Code:

grub> find /hiren98.iso
(hd0,0)

If I bypass the `find` command, I got the other error with `map --hook` command:

Does Hiren's works with ext3 partition? Is there any different between GRUB4DOS and GNU GRUB?

Grub and Grub4dos may have some differences. Dunno which grub you have and how it was compiled so I can't even guess.

You could load grub4dos from grub and do it that way I guess.

See this for more clues. http://ubuntuforums.org/showthread.php?t=1549847

Oh, why didn't I think of that! Follow your suggestion, I solved it by the steps below:

- download grub4dos and extract it
- create grub4dos folder in /boot/grub
- copy grub.exe from above extracted folder to /boot/grub/grub4dos
- add an entry into /boot/grub/menu.lst:

Code:

title Hiren's Boot CD 9.8
root (hd0,0)
kernel /boot/grub/grub4dos/grub.exe --config-file="find --set-root /hiren98.iso; map /hiren98.iso (0xff) || map --mem /hiren98.iso (0xff); map --hook; chainloader (0xff); boot"

One more thing: at the first time, I also copy the menu.lst to /boot/grub/grub4dos and passing to --config-file but it didn't work. Don't know why.

Post this on new thread maybe to get others input.
