I have Virtual box 4.2.12
I have downloaded the ubuntu .ISO
ubuntu-12.04.2-desktop-i386.iso

I followed installation process, when installation ended the button "restart now" is showed. I click it, Virtual Box Crash.
I have to terminate it. ok

I start again the VM, shows ubuntu loading for several minutes, then I get following screen:
"System is running in low graphics mode: your screen, graphics card and input device settings could not be detected correctly. You will need to configure these yourself"

I click OK,

A dialog with 4 options shows up:
-Run in low-graphics mode for just 1 session
-Reconfigure Graphics
-Troubleshoot the errorr
-Exit to console login

I tried various tutorials and caveats. No one works. (endless tentatives, blog, video-tutorials on you tube). Once I get the dialog with 4 ooptions I can no longer go on.

What I have to do to have ubuntu working on windows vista?

Please read Minimum information needed for assistance.

here's the log ) in the meanwhile I'm dowloading ubuntu 13 's iso

Known problem, fixed in SVN.

For the meantime you can use this guest additions.:

http://www.virtualbox.org/download/test ... -85720.iso

the problem is that ubuntu is not starting correctly. I can't install guest additions because I'm not even able to get to terminal :/ I'm happy to see that problem is fixed in current trunk .

Do you know any pair

Vbox Y/Unbuntu Z that is known working correctly? thanks in advance

Either drop to a tty window or boot in rescue mode. Then you can install the guest additions.

in terminal mode I can't install guest additions it says:

"mount /dev/cdrom /mnt
mount: only root can do that"

so I can't execute other commands:
"cd /mnt
./VBoxLinuxAdditions.run
reboot"

Log in as root or use sudo

That don't work

my steps:

1) I login as root
2) I type
mount /dev/cdrom /mnt
cd /mnt
./VBoxLinuxAdditions.run --target ../home/username

here's the output:
Creating directory ../home/username
Verifying archive integrity... All good.
Uncompressing VirtualBox 4.2.12 Guest Additions for Linux............
Extraction failed.
..Terminated.

Sounds like a corrupt download. Check the MD5 or download another copy.

I tried downloading twice from following link:

http://download.virtualbox.org/virtualb ... 4.2.12.iso

the error is always the same.. anyway the archive should be ok ("verifying archive integrity. .. allgood").

Checksums (from 7-zip file manager):


checksums are ok.

Why are you extracting anyway?
Just run it to install. Does it fail then?

this is exactly what I type in the terminal if I skip the the terminal say me that "/mnt" folder is "read-only" and cant execute.

"mkdr: cannot create directory "tmp/selfgz.... blabla" readonly filesystem can't create directory "temp/self..." you should try option "--target OtherDirectory"

cd /mnt then drill to the the VBoxLinux*.run file is.
then run it ./VBoxLinux....run

That's what I already tried the output is the same as above. It says that the folder is readonly. The file is found correctly. It just fails to execute it.
the directory is correct, if I write
few files are showed and "VBoxLinuxAdditions.run" is showed too.

EDIT:
in the case I tried to install Ubuntu 13 and I get all the problems already reported :/
