Flash_Boot_Only_iso? A Possible Suggestions to Mr KNOPPER ?
Hi
Is someone able to suggest to Mr Knopper to eventually create:
1- A Flash_Boot_Only_iso (or other of the same kind?).
Essential Motivations:
1a - DVD's and CD's will soon disappear (I guess).
1b- So one may boot a whole file_iso by the cheatcode "bootfrom=..."
1c- One may install Knoppix when and where one choose to install.
2- This method "temporizes relatively" the usage of CD's
and DVD's
Thanks

Since some years this is within the DVD. If you use mc (MidnightCommander), you can look into the content of the Knoppix DVD ISO and at the positition '/KNOPPIX/' you'll find the file 'bootonly.iso' (and his md5sum). Burn this file to a CD or use it within VirtualBox, VMWare or kvm-qemu.

The boot-only iso and its md5sum is also usually available on current LiveDVDs or LiveUSBs at /mnt-system/KNOPPIX/...

Thanks you for your propositions. I did not know that the "boot-only_CD" is also a file hidden in the places you kindly indicate me.But why to hide it?
I found also this file on the repository of "Free_fr".
Nevertheless I had not well formulated my "idea" which I attempt to make more clear: "my" goal (somewhat") is to "Never use the CD_DVD_Reader".
Evidently this would not meat the profound project of Mr Knopper who
focalizes on "CD_DVD"...
But concerning ONLY "a Flash_Boot", this cannot affect the real project on "CD_DVD"
My Proposition (if possibl!...):
I think that he is surely able to conceive a unique FILE for booting_ONLY_DIRECTLY on Flash even if one DOES NOT POSSESES a Cd_Dvd_Reader.
The Boot_Only_Cd NEEDS necessarily a CD_DVD_Reader (its name tells us about!).
ADVANTAGEs (if possible!...):
1- Booting on such a Flash (No Cd_Reader!) one may use quasi
"entirely an "iso_file" without installing Knoppix (on Hdd or
Burning).
2- So one can Burn or install when wanted via the "iso_file" used
via the "bootfrom=" cheatcode called AFTER the EVENTUAL
"Boot_Only_Flash"
It is essential to understanding me:
AVOID ENTIRELY ANY CD_DVD_READER.
Because I guess that the CD's and DVD's will disappear relatively "soon".
I hope to have been clear enough.
Best regards

Hi, knp:
If the subject of interest is to create a bootonly.xxx file which can be written to a flash drive in a clone fashion and then use the resulting flash drive to boot the ISO file of KNOPPIX CD/DVD resided on another device, rather than dedicating an entire Gigabyte-size flash drive to those files with total size of less than 50MB, most of the Linux bootloaders can be used to boot the existing bootonly.iso file and then the KNOPPIX be started as usual. Although I have only tried to boot the compressed KNOPPIX file (7.2.0) resided on the hard disc using a flash drive containing the matching bootonly.iso file and EXTLINUX related files, I assume that there should be no problem to boot the ISO image of KNOPPIX CD/DVD in a similar fashion.
The list of files on the testing flash drive is as follows,
Code:
knoppix@Microknoppix:~$ tree /media/sdb1
/media/sdb1
├── boot
│ └── syslinux
│ ├── extlinux.conf
│ ├── knx720bootcd.iso
│ ├── ldlinux.sys
│ └── memdisk
└── lost+found [error opening dir]
3 directories, 4 files
*knx720bootcd.iso is the renamed KNOPPIX_V7.2.0bootonly-2013-06-16-EN.iso.

I have not tried the following, but there is this interesting note in Klaus K's description of what's new in Knoppix 7.6.
Why don't you give this a try and tell us if it works for you.
Update: Computers without DVD drive
The flash-knoppix script since Knoppix 7.6.0 supports on-the-fly conversion of a DVD ISO image for direct flashing of a USB pendrive or disk. By using this, the intermediate step of burning a DVD and booting from it, can be skipped. For burning a CD or DVD, only one single .iso file matching your language and version choice, is sufficient. For using this feature, just add the name of the .iso file as commandline parameter to flash-knoppix like this: flash-knoppix KNOPPIX_V7.6.0DVD-2015-11-21-EN.iso

Hi, knp:
I have just tried out to boot the ISO image of KNOPPIX V7.6.0 DVD using the method as mentioned in the post #5, and the outcome is sweeeet... Also, booting previous releases of KNOPPIX DVD (7.2.0 and 7.4.2) using their corresponding bootonly.iso images are all OK! By the way, the content of extlinux.conf used for the preliminary test as mentioned in the post #5 is as follows,
Code:
LABEL knx720
LINUX memdisk
INITRD knx720bootcd.iso
APPEND iso raw

Thanks you for your very good idea for CREATING a boot_Flash_only.
But one seems to NEED knop_7.6 installed somewhere (Hdd,Dvd...).
Because one has to "PICK" somewhere the "boot_only_CD.iso" File.
(your #5... Code) and (#2,#3 of Schulz and utu).
This file is not furnished on the repositories.
Does your method need some kind of formatting the Flash?
Do "Creating DIRECTLY Folders and Copying Files" suffice to make
the Flash bootable?...
In your Code you refer to some "extlinux.conf".
"ext"...(= "extended" for your own "notations"?) (="Extended_FS"?)
You are a real "Linux_Expert" on the contrary of some of your
suggestions in other threads!
You discover that I am an entire newbie for many reasons.
Thanks you and see also the last post of utu (#6)
@utu
This seems to be my goal: Not any previous use of DVD!! Thanks you.
I shall read the entire text you refer to and send you my
experience on about one week.
Best regards to all of you.

a conjecture
.
I think there may be a conceptual problem here.
I believe it likely to be true that once you have a Knoppix 7.6 LiveDVD or LiveUSB,
the Knoppix menu function, flash-knoppix, in Knoppix 7.6, will use a dd operation
to prepare other additional LiveDVDs &/or LiveUSBs using hybrid isos as sources.
It appears that zenity prompts are there to assist locating and specifying appropriate
media and isos.
If the Knoppix 7.6 information is correct, this seems to infer that this function of
flash-knoppix in 7.6 is itself an upgrade which provides this new function, presumably
not previously a feature of flash-knoppix.
This may explain how having a Live 7.6 Knoppix might allow making Live systems of
other versions of Knoppix Live system isos, like 7.2 and 7.4.2, for example.

Did you really read my posting? You don't need to install Knoppix; only download the ISO and open it within mc.
