Can't boot after coping VDI to new drive (or possibly just upgrading to 17)

  • 772

I tried to copy an Ubuntu VDI/Virtual Box image to another drive. Now when I boot up I get a black screen with a cursor. If I use host & F1 I can log in via TTY but I can't figure how to boot. I have tried reinstalling guest additions and upgrading, but no dice.

I tried the advice here 12.04.3 can start only after press "resume" in rescue mode (every boot) - problem with Nvidia driver and it still isn't starting but now it flashes different sizes before finalizing at a little black screen with a cursor.

When I try manually running x (sudo startx) it gives me an error of...

error setting MTRR (base = 0xe0000000, size = 0x04200000, type=1) No such device or address (6)

Also after setting no splash etc I now see a console error on boot...

enter image description here

From here I can still boot into the tty but X still won't start

When I run sudo X -configure

I created a 16 version from scratch and it worked fine. Updated to 17 and got the same thing happening again.

    My inelegant solution was...

    1. Create another virtual drive attach it as SATA
    2. Startup failing machine and mount via terminal the new vdi
    3. Copy all files to the new drive
    4. Shutdown bad machine
    5. Create new Ubuntu machine
    6. Mount new drive as well as OS drive
    7. Copy files over to New OS drive

    There might be a way to just mount the old broken drive as a second drive, but mine was encrypted and I couldn't get it to work.

    I will still give bounty to anyone that can get the old one to actually boot.

  2. I don't exactly know what you mean by 'new drive' but creating a new OS from a VirtualBox 'VDI' image of file should be done like this:

    1. Have the 'VDI' file ready in any folder

    2. Create a new OS on Virtualbox device using the usual steps, but when at the 'HARD DISK' step choose the option 'Use an existing virtual disk file':

      enter image description here

    3. Select the 'VDI' from step 2.

    4. Set up the Network and choose the 'Bridged Adapter' option:

      enter image description here

    5. Now start the Virtual VM.
