grub4dos, .iso images and (hd32) or (0xFF) mapping, Post here ONLY reports of working setups! External links Options

[was_jaclaz]

This thread is reserved for people reporting their success using newish releases of grub4dos that allow for direct booting to a .iso imaging through mappig the ISO image to (hd32).

Ideally, any user who had some success with this way of booting can post here reporting what he succeeded with and how he did it, links to other boards, tutorials guides related to the matter are also welcome.

PLEASE NO request for help here, post them in the grub4dos forum.

PLEASE NO "Nice, thank you!" kind of posts.

PLEASE NO "Ha, this is not useful!" type of comments.

This thread should become simply a list of working setups, no more, no less.

Thanks for cooperation.

I have had success with the feature with a ram-loading LiveXP from usb stick with grub4dos loaded to mbr of the stick. That is, BootSDI script is used and hence files from Windows 2k3.

Working for me:

CODE

title LiveXP - mem
find --set-root --ignore-floppies /!images/iso/LiveXP_RAM.iso
map --mem /!images/iso/LiveXP_RAM.iso (hd32)
map --hook
chainloader (hd32)
boot

Not working for me (although works from harddisk if grub4dos is started from boot.ini entry):

CODE

title LiveXP - direct
find --set-root --ignore-floppies /!images/iso/LiveXP_RAM.iso
map /!images/iso/LiveXP_RAM.iso (hd32)
map --hook
chainloader (hd32)
boot

Objective:
To directly boot the DBan ISO file stored on a CD-ROM.


This post relates to:
Grub4DOS v 4.0.3
http://grub4dos.jot.com/WikiHome
DBan v 2.0 Beta ISO
http://sourceforge.net/project/downloading...042900_i386.zip


Sofware tools required:
mkisofs
http://cdrecord.berlios.de/private/cdrecord.html
ImgBurn
http://imgburn.com


File Structure

ISOBuild

\iso_root

\images

\dban-beta.2006042900_i386.iso

grldr
menu.lst

mkisofs.exe

menu.lst

CODE

title WIPE DISKS   ---   DBan 2.0.0 Beta
   map  /images/dban-beta.2006042900_i386.iso (hd32)
   map  --hook
   kernel (hd32)/ISOLINUX/DBAN.BZI nuke="dwipe --method zero" silent
   boot

Note: "--method zero" sets the default wipe to a single pass of 0 written to disk. Other methods are listed within the DBan interface.


ISO Creation

CODE

mkisofs -R -b grldr -no-emul-boot -boot-load-seg 0x1000 -volid "Volume Name" -o bootable.iso iso_root

ISO Burning
Use ImgBurn to burn "bootable.iso" to CD-ROM


Result
A bootable CD-ROM which displays a menu from which DBan can be started.

Acronis True Image 10/Disk Director 10.
Use Bootable Rescue Media Builder to build the ISO. Name it acronis10.iso, copy it wherever you want.
Menu.lst for it:

CODE

title Acronis media
find --set-root /acronis10.iso
map /acronis10.iso (hd32)
map --hook
root (hd32)
chainloader (hd32)

Paragon HD manager 8.0 Special Edition. This is still available with a free registration:
http://www.vnudownloads.com/hdm8_se-20070203-0000-en.exe
http://registry.paragon-software.com/hdm8pers/

When you install it get the ISO from \Program Files\Paragon Software\Hard Disk Manager 8 Special Edition\ISO\bootcd.iso.
If it's not there, open the program and tools->recovery media builder and make it.

I renamed the ISO to hdmanager.iso, copy it wherever you want. Menu.lst for it:

CODE

title Paragon HD manager 8.0
find --set-root /hdmanager.iso
map /hdmanager.iso (hd32)
map --hook
root (hd32)
chainloader (hd32)

For both of them- if you change map --mem /hdmanager.iso (hd32) / map --mem /acronis10.iso (hd32)
you will be able to manipulate the partition, even overwriting the respective ISO or partition, as they the ISO will be running entirely from RAM.

Tested with grub4dos-0.4.3-2008-03-14 on qemu

FreeDOS base CD (fdbasecd.iso) - success

CODE

title fdbasecd.iso (0xFF)
find --set-root /fdbasecd.iso
map /fdbasecd.iso (0xFF)
map --hook
root (0xFF)
kernel /isolinux/data/memdisk
initrd /isolinux/data/fdboot.img

or

CODE

title fdbasecd.iso (0xFF)
find --set-root /fdbasecd.iso
map /fdbasecd.iso (0xFF)
map --hook
root (0xFF)
map --mem /isolinux/data/fdboot.img (fd0)
map --rehook
chainloader (fd0)+1
rootnoverify (fd0)

Note - mapping as (hd32) resulted in missing CD error.



FreeDOS full CD (fdfullcd.iso) - partial success

CODE

title fdfullcd.iso (0xFF)
find --set-root /fdfullcd.iso
map /fdfullcd.iso (0xFF)
map --hook
root (0xFF)
kernel /isolinux/data/memdisk
initrd /isolinux/data/fdboot.img

or

CODE

title fdfullcd.iso (0xFF)
find --set-root /fdfullcd.iso
map /fdfullcd.iso (0xFF)
map --hook
root (0xFF)
map --mem /isolinux/data/fdboot.img (fd0)
map --rehook
chainloader (fd0)+1
rootnoverify (fd0)

Note - mapping as (hd32) resulted in missing CD error.

Installing option works. Live CD options do not.

Not working for me (although works from harddisk if grub4dos is started from boot.ini entry):

CODE

title LiveXP - direct
find --set-root --ignore-floppies /!images/iso/LiveXP_RAM.iso
map /!images/iso/LiveXP_RAM.iso (hd32)
map --hook
chainloader (hd32)
boot

Interestingly, the above works if grldr is written as the bootsector of the ISO image!

situation:

• XP encrypted with TrueCrypt installed on internal harddisk
• using USB pendrive
• grub4dos installed into MBR on USB pendrive
• booting USB pendrive with BIOS
• tc.iso is the rescue CD iso image created by TrueCrypt system encryption wizzard

pros:

• bootmanger on USB pendrive will be never overwritten by any operating system, therefore no need to fix it ever
• the MBR of the internal harddisk does not need to be touched
• the bootmanager appears first where you can choose what operating system you like to boot
• when choosed the rescue image you can enter your password and boot windows
• you don't need to burn the TrueCrypt rescue cd, you save one cd you may need never, when encrypting many computers you have just a collection of iso images on USB and not many cd's

title tc.iso
map --mem /tc.iso (hd32)
map --hook
chainloader (hd32)

Works very well!

Here is a GRUB4DOS section that I am currently using to run Parted Magic 3.0 from the pmagic-svn.iso. The was pulled off of the Parted Magic forum and slightly modified. I have tested it on both a USB Thumb drive and CD, both worked fine. I used the latest ISO available from http://partedmagic.com/beef_drapes/ .

CODE

find --set-root /boot/IMG/pmagic-svn.iso
map /boot/IMG/pmagic-svn.iso (hd32)
map --hook
root (hd32)
kernel (hd32)/pmagic/bzImage noapic root=/dev/ram0 init=/linuxrc keymap=us livecd vga=791 sleep=0 ramdisk_size=25000 noeject iso_location=/boot/IMG/pmagic-svn.iso
initrd (hd32)/pmagic/initrd

[KES]

SOME WAREZ RELEASE
copy memdisk and SOME WAREZ RELEASE.iso to root of drive.

title SOME WAREZ RELEASE
kernel /memdisk
map /SOME WAREZ RELEASE (hd32)
map --hook
root (hd32)
initrd /BOOTCD/SOME WAREZ RELEASE.IMG

Notice: you can specify (fd0) or (0xFF) or (hd32) all works fine
Notice: /BOOTCD/SOME WAREZ RELEASE.IMG must be uppercased!

SERVICE POST:

The above post has been edited to protect the innocent.

KES, to clear things:
We DO NOT support WAREZ on this board, see Rule #1:
http://www.boot-land.net/forums/index.php?act=boardrules

We DO NOT like WAREZ.

We DO NOT help people add WAREZ to their multiboot whatever.

We DO NOT make available .scripts that support WAREZ.

We DO NOT in any way encourage or support the use of WAREZ, not even indirectly.


and to top it, your original entries are however WRONG.

You've been warned, another post related to WAREZ and I'll see you out of this board in no time.

Not the most brilliant first post I saw....
