Advice Please on Installing Ubuntu in Virtual Box in Windows 7

acc

I have installed Virtual Box version 3.2.12 r68302 in Windows 7 Home Premium, and want to create an Ubuntu virtual machine.

I would be grateful for advice from you experts on the following issues.

(1) Using the DOS command net use X: \\vboxsvr \share, typing 'D:\VirtualMachineShare' for '\share' fails with error 53 The network path was not found, when explorer does find that folder.

(2) Creating a new VM initially shows VBoxGuestAdditions.iso as inaccessible, so the drop down entry below has to be selected, which then shows that iso with file size 31.61 MB.

(3) Starting the new virtual machine using the ubuntu-10.10-desktop-i386.iso file gives the error below.

Use Create New Virtual,
Name = UbuntuVM
OS = Linux
Version = Ubuntu

Base Memory Size 512 mb

Virtual Hard Disc
[/] Boot Hard Disk
Create new hard disk

Dynamically expanding storage
\Virtual Machine\UbuntuVM.vdi
8 GB

Click Start

Browsing to the ubuntu-10.10-desktop-i386.iso file causes:

VirtualBox - Error
Failed to open the cd/dvd image ...
Cannot open the medium ...
VD: error VERR_VD_RAW_INVALID_HEADER opeing image file ...

I don't have any suggestions for the first two, but for the third, have you tried writing the .iso file to CD as an image, rather than pointing at the file?

If you've already done that, what did you use to write the CD? I've had similar problems (in reverse, running Windows under VB under Linux), and these seem to have been caused by slight differences between the way that Windows and Linux-based programs write .iso to CD.

As gaming_guy said, download the iso image again. My guess is that the file is corrupted hence the error message on start-up. I'd also strongly recommend downloading VirtualBox 4.0.2 and the corresponding VirtualBoxAdditions image. The version you are currently using is quite old.

Thanks guys. The ubuntu virtual machine is now working fine.

As suggested I downloaded the ubuntu-10.10-desktop-i386 iso file again and this time the file was a bit larger than the previous file! I also downloaded the latest VirtualBox, 4.0.2 against my previous 3.2.12.

The folder sharing had to be done in the guest using commands like 'sudo mkdir /media/vboxshared' and 'sudo mount -t vboxsf SHARENAME /media/vboxshared' rather than the 'net use X: \\vboxsvr \share' I originally tried from the host.
