Cannot boot, error out of disk - after readonly system error !

[naarkhoo]

Let me tell whole the story !
I just installed wine and other packages, and in meanwhile noticed that I don't have enough space, then tried to remove some other files but discovered that the permission is changed and evertything is read only ! even for sudo !!! the error was some thing like readonly system error ...

I knew that If I restart, probably I encounter with starting up error and due to the cpu was working 100% and I coudn't halt it ! I reboot my machine ... and now stuck with starting up !!

first it come up with out "out of disk"

and then several error, like

mount: mounting /dev on /root/dev failed: no such file or directory
mount: mounting /sys on /root/sys failed: no such file or direcotry
mount: mounting /proc on /root/proc failed: no such file or direcotry
Target filesystem doesn't have /sbin/init.
No init found. Try passing init= bootarg

and then

BusyBox v.1.13.3 ...
and (initramfs)

By typping "ls" seems I have
"dev","scripts","bin","conf","lib","proc","var","r oot","sbin","etc","init","sys","tmp"

I also did try to load with USB boot loader, but seems it doesn't work

Ouch...!
How big is the partition which is apparently running out of room?
How big is the hard drive?
If these are apparently big enough already, and it is not an issue, you might want to try checking the drive for errors, then reinstalling.

The hard drive is 32Gig and the partition which the Ubuntu is installed is around 10Gig !
Do you think its hard drive issue ?! if yes, Is there any way to restore my system ?! Sort of removing all the packages that I got from Synopsis last time ...

Well, you can install Linux onto a drive as small as a 2GB USB stick. Virtual memory, called Swap in Linux, is a hard drive area about the size of the RAM which is set aside at installation, eg: if you have 2GB RAM, then the swap space size is usually 2GB also.
This doesn't look to be too much of an issue in your case.
Why the small 10GB partition size anyway?
You can easily get a new 500GB drive for around $50 or less. Would this not be easier than worrying whether your drive has enough space?
If you have a special installation or programs, you can quite easily use the dd_rescue program to make an exact error free copy of your existing installation.
If you need to do this, I have done it recently myself, so I can show you how.
Requires you to use the terminal command line, but it is not so hard.

Only thing is, it will copy over the existing problems that you described in your first post, so this will only put the problem onto a bigger drive.

If it says Out of Disk Space or similar, then pretty much all bets are off after that. It may be reporting all sorts of errors like you describe (mounting etc) simply because it can't write any more to the drive it wants.

I think you may find that all the packages you have installed have taken up all the available space. You might not have downloaded many GBs of programs, but they will have been expanded, etc when they are installed, and tried to give themselves disk space that they want.

If you have the option, get a bigger drive, and do a new installation.
If not, then try a re-installation of the OS the the existing drive.
