HOT: Here is How to Install linux without cdrom!!

[Faraz.Fazil]

Creating iso images is simple too.

You can use dd or mkisofs to create them in linux

First mount the cdrom using mount command.

To create iso images using dd command:
=================================
dd if=/dev/cdrom of=filename.iso

To create iso images using mkisofs command:
====================================
mkisofs -o filename.iso /mnt/cdrom

To create iso images in windows, use a tool like WINISO or nero.

Its that simple.What did u not understand?

i've got Redhat 9 on 3 cds but i don't want to install it through my cds,i want to make iso of my cds on my hdd.

if u have already inserted the linux bootable cd in the cdrom....and u r booting from floopy with boot.img written on it.........then mostly it directly jumps to cd from floopy just after it reads image from floopy....
in other case it askes u after some screens ..where is the image of cd...either cd or partitions of hd.....they may be fat or ext..

[Faraz.Fazil]

Well, i think it may be considered as a side Info.
Becoz, there is no use in using boot floppies to start linux setup with the cd already inserted into the cd drive...and then installing from the cd.

The main use of using Linux Setup Boot floppies is to install linux without a cdrom/cd
.

if u have already inserted the linux bootable cd in the cdrom....and u r booting from floopy with boot.img written on it.........then mostly it directly jumps to cd from floopy just after it reads image from floopy....

wt i tried to say was... i had experienced.
i installed rh7.3 on the pc with cdrom but it didnt supported cd-boot.
and i knew that i have to use boot.img but wheni reads img from floopy it directly jumped to cdrom....then no difference btween booting from floopy or cd...

wt the new thing i tried to post is if ur pc dot support cd-boot and u r using floopy to boot then then there wil be not difference in instalation after it reads img from floopy and control jumps to cd rom...

so if u trying to install from .iso dont put linux bootable cd in the cdrom then u boot from floopy with boot.img file then u can have the option either u want to install from hd or cd...other wise by default it goes for cdrom -instalation

[farhanksa]

i got debian iso i cant open the iso as u posted in ur post ..that u dont need to worry if u dont have boot.img... use winrar to take the boot.img file out of .iso??

how to do that...i tried it with winrar but it didnt work

[Faraz.Fazil]

Good point.

so if u trying to install from .iso dont put linux bootable cd in the cdrom then u boot from floopy with boot.img file then u can have the option either u want to install from hd or cd...other wise by default it goes for cdrom -instalation

[Faraz.Fazil]

Still no problem.
I use winrar with iso's and it works fine.
If you still cant use winrar to open/extract iso contents, worry not.
There are tons of programs that let you do the same.

Download and Use WinIso or ISobuster.

Here is what the makers of WinIso say:

=======================================================
WinISO is a CD-ROM image file utility that can convert BIN to ISO, extract/edit/create ISO files directly, make bootable CDs and as a BIN/ISO converter/extractor/editor.

It can process almost all CD-ROM image file(s) including ISO and BIN. With WinISO, you can add/delete/rename/extract file(s) within image files. You can convert image files to the standard ISO format and you have the ability to create ISO image file(s) from a CD-ROM.

The operating system requirements are Windows 95, Windows 98/98SE, Windows Me, Windows NT4, Windows 2000 or Windows XP.
========================================================

Download and more info: www.winiso.com
Download of Isobuster: www.isobuster.com

Make sure you make a copy of the iso image, and use the copied iso to extract the contents so that the original iso may not in any way get corrupt.

i got debian iso i cant open the iso as u posted in ur post ..that u dont need to worry if u dont have boot.img... use winrar to take the boot.img file out of .iso??

how to do that...i tried it with winrar but it didnt work

Also note that, debian has a slightly different procedure from redhat.

Some people have reported to use loadlin to install debian on win98 dual boot box successfully.

Debian also provides an install.bat to accomplish passing the
right arguments to loadlin. You might check out a debian mirror

(http://http.us.debian.org/dists/stable/ ... 6/current/ should
work) and see what they do in the install.bat file.

Also you may get hold of an install boot disk for debian from debian.org

[Faraz.Fazil]

For debian, also check these:

http://www.debian.org/releases/potato/i ... ot.en.html
http://www.debian.org/releases/slink/i3 ... thods.html
http://www.debian.org/releases/slink/i3 ... ot.en.html
http://www.debian.org/releases/slink/i3 ... m-floppies
http://www.debian.org/releases/slink/i3 ... ate-floppy

Also 'tftplilo' can be used to boot the Debian installation system.

u should place the iso image in FAT or ext partition........boot.img is cant to read from NTFS

[Faraz.Fazil]

Yup...

The iso image must obviously be either on a fat/fat32 or ext2/ext3 partition.
Iso images located on ntfs partitions would not work...also, as a side note, most kernels like those on redhat by default come without ntfs support and you have to recompile your kernel to include ntfs support.

At this moment only stable ntfs read only support is available..
Ntfs write support is available in 2.6 kernel but is highly experimental and is not advised.

Also you cannot access ntfs partitions in dos....unless u use a utility like NTFS4Dos professional by erd.
