This is the mistake that i've done :

First of all go to /etc/apt/ folder from terminal or using file manager ...

than copy the content of source.list in to your adequate source.list.

Create a file named source.list.bt and paste the same content

In the end open the Final.txt copy - paste in your terminal to accept a public key and that's it , your done

The files that I've uploaded are without .txt suffix

For some reason it's dropping me in BUSYBOX , I've tried a lot of things to fix it but non of them worked.

Please Help me !

This is the link of the files that i've used to configure my PC .

what is your problem exactly ...please explain in more detail from the beginning
I am waiting for your answer to help u

OK , i was working with my PC Running ubuntu based OS and then opened synaptic package manager to install something but the manager was having problem finding the source of packages , i opened the terminal -> cd /etc/apt then copied then changed the source serveres , and replaced the original ones with this servers :

deb http://all.repository.backtrack-linux.org revolution main microverse non-free testing
deb http://32.repository.backtrack-linux.org revolution main microverse non-free testing
deb http://source.repository.backtrack-linux.org revolution main microverse non-free testing

and again tried to install a program from synaptic , but this time it required GnuPG(PGP Public key).
Then again opened the terminal -> wget http://all.repository.backtrack-linux.org/backtrack.gpg && sudo apt-key add backtrack.gpg && sudo apt-get update

then installation worked well , i was able to install every package from synaptic , everything looked fine , until i rebooted the system.

After that every time that i'm trying to boot the old system it drops me to BusyBOX.
Please tell me if you want more detailed explanation

now I get the whole picture...
the first qeustion: why using the terminal? ..u could used the GUI it is much easier and less error-prone.
now lets get to the problem..
I think the problem is in X (the X windows system)
you MAY have to reinstall X from the Command Line
You must prepare a live cd to use it to read the filesystems,backup your data,etc
you still have ubuntu it is a good choice..

check this out
http://en.wikipedia.org/wiki/Busybox#Commands


also try to press alt+ctrl+F1 and see what will happen..if a command line interface appeared and asked for login data:login and the you have an active shell to work from then type "startx" and see what will happen ..the foolong commands will be useful:
reboot
su
sudo
halt

Sorry about the link :

i've been using linux for 3 years now.
I read a lot of books about linux , mostly Debian , RedHat system admin etc...
And i'm already in first Terminal(alt+crl+f1) , and tried 6 others , but since i'm Dropped in busybox none of them works .

Theres the output of busybox :
-----------------------------------------------------------
Gave up waiting for root device common problem :
-Boot args (cat /proc/cmdline)
-check rootdelay = (did the system for the right device ?)
-Missing modules (cat /proc/modules): ls /dev)
Alert /dev/disk/by-uuid/my UUID does not exist , Dropping to a shell!

Btw i've tried fixing the UUID from grub bootloader , i think that's not the problem , but anyway i'm not sure.

Again Thank you so much !

what we can do now is to backup the data and reinstall the system

So , no way to fix it ? I have three systems installed on my machine , This one (that's not working) , BDS distro and another debian based OS(which i'm currently working with) installed between them . What about i backup the data and instead of reinstalling the same thing , i install debian and put all the datas there . What do you say ?

And btw i haven't noticed before , e.g when i try to delete files using Live cd , it stills full , so that say i had 0 byte free space , i deleted 2 GB files and it stills 0 byte free space , this thing is going worst and worst .

may be the files moved to the trash folder
go to ~/.local/share/Trash and check "files"

http://www.linuxarticles.org/2011/06...-shell-prompt/
http://www.withsteps.com/624/unixlin...-commands.html
may be you don't have the permission to delete the files ..try to delete them as a root..

back to the main problem..you should check which run level you are on by the following command
runlevel

what are the options in you grub menu for the broken distribution?
you may use one of them to enter the single user mode which is for root only and try to reconfigure the system but still the picture is not clear for me .. you didn't provide enough information..waiting for more

hey man what did u do to solve your problem..?
I am back again..Stronger than yesterday.. there is nothing but my way..
wish I could help u .. please inform me about the situation.
