Kubuntu guest OS fails to boot from CD

[peterRB]

Running VirtualBox 4.0.8, on a Windows 7 Pro host laptop. My Kubuntu 10.04 guest will no longer start up -- something went south in the virtual disk image after the battery ran out.

So: I want to boot linux from the kubuntu 10.04 live CD, to hopefully run fsck on the virtual hard-disk. VB recognized the CD. I get the choice of running or installing kubuntu, or three other choices. I choose run, Kubuntu goes through a few screens and reads a lot from the CD with the Kubuntu splash screen up, then it stops, it's frozen. I hit ESC and see boot-up log in window, ending with this:

Code: Select all

Source list entries for this disc are:
deb cdrom:[Kubuntu 10.04.1 LTS _Lucid Lynx_ - Release i386 (20100816.2)]/ lucid
main restricted
Repeat this process for the rest of the CDs in your set.
W: Skipping nonexistent file /cdrom/dests/lucid/main/binary-i386/Packages
W: Skipping nonexistent file /cdrom/dests/lucid/restricted/binary-i386/Packages

In Windows, I see the CD does in fact contain these files, gzipped:

/cdrom/dests/lucid/main/binary-i386/Packages.gz
/cdrom/dests/lucid/restricted/binary-i386/Packages.gz

So seems to me, the booter (a VirtualBox emulation of grub perhaps?) is told to look for source file "Packages" and doesn't recognize "Packages.gz". On my other kubuntu 10.04 installation (physical not virtual), the same CD boots up fine. So no problem with the CD image.

Any way for me to get a fix for the booter? Or is this some other problem?

Thank you.

Update to yesterday's post:

I also tried to have VirtualBox start the VM from CD/DVD device hooked to the .iso image file stored in Windows, instead of from the physical CD/DVD device. Result: Same failure in both cases.

This really seems to me like a VirtualBox problem, rather than a kubuntu problem.
