Windows XP Question

Getting into the system BIOS varies from one PC to another.

Click here for some suggestions.

The BIOS editor will also vary, depending on the PC type, but generally you should search through the options ("Advanced BIOS Settings" is a good bet, if you have that option) until you find a reference to Boot Device Order (or something similar).

There should be enough prompts on the screen to tell you how to change the sequence, so that your PC looks for the CD-ROM drive first.

Thanks for your reply.

I have another question please:

How i can get the DOS prompt from Widows Xp ?

Start -> Programs -> Accessories -> Command Prompt

I tried to boot from CD using DOS command , but i got the message :

Warning Not enough free memory< Load buffer size>

I there any way to fix this problem ?

Thanks for help.

You can't boot from a CD once XP is already up-and-running. A DOS window will only let you have a small-ish "virtual machine".

To boot XP from a CD, use the BIOS boot sequence change as described earlier.

[XP is not like the old stuff (Win3.2 etc) which loaded on top of DOS. XP replaces MSDOS (it is a DOS (Disk Operating System))].

Actually, the CD instructions say:

You can start Live CD from DOS prompt as follows:

Boot your DOS and type:

D:

CD\BOOT\DOS

xxx.bat

May be we need to start the computer direct in DOS mode without Windows or increase the buffer memory size ??

What CD? Can you supply any useful details? A link, perhaps?

"Boot your DOS" implies that you have a PC with DOS, not XP. If you have a PC with (only) XP, you don't have DOS (just an emulation of it, provided by the Command Prompt window, which is not the same thing as "old-fashioned" DOS).

The CD contains ISO image of a software called: Backtrack3 Final release ISO.

An ISO is not bootable - ever.

For DOS, you need a DOS bootable CD, quite rare things......

Even when its not an ISO anymore, that still does not 100% mean its bootable either, but it may be.....

Its not easy to help you with such information.

Ok, First of all....

Backtrack is a tool to sniff on the WiFi networks in order to get "certain" information regarding the security of the network you point to......in some other places that may be called "hack"......

Second...

Backtrack is a Linux application, that's why you need the ISO bootable CD, because that thing loads Linux at the very beginning and then runs the Backtrack application, maybe the ISO you got is either incomplete or corrupted, my guessing is that you got the ISO file from some underground site and then burned the CD....

The steps you are following are the steps for create a bootable pendrive (as far as I could imagine based on what you said about open a DOS prompt and type the instructions you said)

What you have to do is go through the BIOS and change the boot order or first boot device to make it the CD or DVD or whatever is named on the BIOS then just let it go, it must work if the ISO is OK

As stated before on most computer systems the BIOS is the proper way to change boot order. On some old computer systems they limited what you could boot from ie:hard drive or floppy drive most pre-Pentium systems.

As to the instructions to start DOS "Disk Operating System" most likely its for pre windows operating systems. DOS 1-6. The reason is to load the drivers for the CD drive.

Then most likely the live iso would then execute its program in taking over the computer and then load its lunix based operating system. Where operating a WINDOWS operating system the DOS is a virtual window to allow you to run DOS based programs Not to install another operating system when running Windows.

I think the PC can't boot from the CD because the xxx.bat file is contained inside a "directory" in the CD.

I believe if this command:

BOOT\DOS

xxx.bat

can be placed on the CD, you get booting from the CD, because the file xxx.bat is inside the DOS directory which is inside the BOOT directory,but i don't how to do it.

didn't google already change the way we think?

a google search using the keywords "how to boot from CD" can help. try this one, for example:

So,did you find how to solve the CD booting problem in our Case ?

This link could imply that the software needs Linux not DOS:-

My PC is automatically boots first from the CD drive,i down loaded BackTrack3 Final Release ISO, then burnt the ISO image i downloaded(as it is) into CD,but still the PC doesn't boot from the CD.

Before you burn the CD, you must find an option (usually a checkbox) to create a bootable CD. If your CD burning software doesn't have this as an option, find one that does. (Check here).

push F12.

GA

That is the trick sir.

The function of the F12 key is system dependent. As previously suggested, see further details here.

Sir,i already tested before for the ISO image CD of Backtrack with the PC set to start booting from the CD ,it will not boot from the CD unless you push F12 during start up.

My be it is special case for Backtrack ISO CD.

Download Backtrack ISO image and try it.

Ragab,

you are being watched. All activities here on CR4 have to do with Computer break ins, network sniffing, wireless lan hacking.

At least you still have to ask for basics that one would assume a good hacker will know. You still remain dangerous to yourself and the people around you. Stop with what you are planning to do. It is unlawful!

Can some Admin please step in here? You are unwillingly helping an almost if not already criminal!

Sir,this for educational purposes.

I'm using softwares already on the net,i didn't invent any by my self,if it is illegal they will be never on the net.

Evey wireless network owner has the right to protect himself from me but not to attack me.

I'm doing this for satellite signals as well, I'm doing this for my living sir, i don't have another job to do sir.

You can buy a knife and still should not back-stab your neighbor. Illegal is what you do WITH the tools. It does not depend on availability OF the tools.

But I take it you are attacking your nneighbours as they need to defend themselves while (funny enough) they are not allowed to attack you!

I think you are a case that needs to be stopped right in its track.

You intercept satellite signals just for a living? Maybe you explain what you are doing and where the education is in your questions and what you are trying to achieve. So far it sounds very dodgy indeed!

Regards Werner

You are really naive.....there are hundreds of pieces of software (if now hundreds of thousands even!) that are totally illegal to use........available on the web......its a hackers delight!!!!

Luckily for the honest people here, hacker software is VERY often "Hacked" and contains viruses and other unwanted things, so the people using the software will often become "BOTS" or at least their computers do......so be warned, what you are doing is both illegal and dangerous to your computer.

What John was trying to tell you (as I and others also), is that you cannot boot from an ISO image!!!

You must use special burning software to tskr t6hst imsge and burn a proper copy onto a new CD that should be bootable.

THEN you boot using PF12 on your system.....this varies from system to system as others have mentioned already.

Best wishes.
