is there a way to boot livecd project from iso from bcdw

[carfan]

Is there a way to use bcdw and boot a livecd project from an iso. Im having problems with the boot sequence.

It loads "Setup is checking" boot screen but then switches into windows setup program which is on the same dvd instead of continuing to boot the project. Is this the fault of setupldr.bin??? If so, can it the boot chain be changed???

Thanks

try using diskemu instead of bcdw to load iso's but it rarely works with live cds since after it boots it looks for files in its root folder and fails and live cd like knoppix is another head case.

A CD drive can be accessed direct by hardware and by BIOS routines.

BCDW support BIOS support.

Booting ISO works as long as a livecd project use BIOS only.

Booting fails, if hardware is acessed.

Or windows setup program use hardware acess and find files at hardware.

Files from CD are read next, not from ISO file.

Currently there is no ISO file boot with direct hardware support.

1) i copied the "KNOPPIX" folder from my knoppix live cd... it has the knoppix file system in it... 700mb something single file plus some image files among other things and put it in root of my multi-boot iso...

2) heres what i use in cdshell.ini

if $lastKey == key[2]; then memdisk /KNOPPIX/BOOT.IMG

3) boot the iso via vmware and i select 2 key to boot for knoppix and it does... boot goes well and it tries to find the hardware for the 700mb knoppix file system but it couldn't and drops me right there instead.

=======================

i'm curious to know if this is a vmware error???

cause in the knoppix readme file, it says in order to create a knoppix bootable cd all you need is the "boot.img" file located in the "KNOPPIX" folder...

so when i dump the whole knoppix contents into a cd and burn that cd using the bootable option in nero and load the "boot.img" file then it should work right ok...

why doesn't this work with multi-boot dvd or is this a vmware error...???

fails in both vmware and pc run. first. i have a windows setup program on root of dvd. when livecd is accessed from bcdw to boot the normal first boot screen appears. after hardware is detected, the boot should then proceed to load the livecd project. instead, the boot sequence finds the i386 folder on the dvd root at continues to boot from that. what i want to do is change the boot sequence to continue the livecd boot sequence. setupldr.bin or what ever controls the sequence needs modified for the livecd project which in my case is livexp or some other nativeex project.

thanks

did you prepare your livexp cd with UBCD4WIN...

i had experienced this problem/error myself...

it goes away when you delete the "BOOTFIX.BIN" file from the i386 folder...

No, Its from a winbuilder project uxp which allows the windows setup cd and 1 livecd project to co-exist on 1 dvd. I was trying to allow more than 1 livecd project on the dvd by booting to and iso.

boot goes well

There are BIOS routines used that early. Basic files are read. Kernel file is loaded to RAM and processed.

and it tries to find the hardware for the 700mb knoppix file system

Knoppix seek knoppix file at real hardware.

There is no image at real hardware. This fails.

Knoppix is a example:

BCDW ISO file support BIOS calls, but no hardware calls.

BCDW ISO file works as designed.
