Installing Ubuntu 8.04 Hardy Heron in Virtual PC 2007

Sei que a versão 8.04 não é a mais actual, mas é a que está aqui e posso usar de momento.

Instalando isto no Virtual PC 2007, (em 2005 Server crasha imediatamente) obtemos um belo erro:


Segundo o blog “Arcane Code” basta seguir os seguintes passos descritos na página (Escolher o modo “Safe Mode Graphics”, escolher “Try Ubuntu”).

No entanto verifiquei que tal apenas não é suficiente, sendo ainda necessários mais alguns passos…. Após vários testes de sugestões que apareceram nos comments, consegui finalmente instalar o Ubuntu com a seguinte dica:

Hey folks,

Here’s another workaround for the processor error issue:

– At the prompt, press F4 and select “Safe graphics mode”.
– Then press F6 and delete the part that says “quiet splash –” and replace it with “vga=791 noreplace-paravirt”.

You can read about the “noreplace-paravirt” option in the Linux kernel documentation.

It will take a couple minutes to boot up. Technically you could leave the “quiet splash …” part in, but it would be easier to debug problems if you can see the kernel messages (the splash screen doesn’t work anyway). The vga=791 is also not absolutely required, but I find that it allows the system to boot a bit faster since it doesn’t have to rescan the video resolution.

Hope it helps.


Bem…. obrigado ao Steve pela excelente dica, que salvou a install, dado que nem o “noapic nolapic vga=791” serviu. 🙂


  1. Claro que depois falta ainda conseguir bootar isto, sendo que para tal é necessário, nos passos abaixo substituir vga=491 por “vga=791 noreplace-paravirt”.

    “Seemed to lock up on reboot (black screen for a while), so I reset it.
    I hit “esc” at grub, then I selected the “kernel” option, and hit “e” to edit, and added vga=791 to the end of the line (since noapic and nolapic already seemed to be on the line), then hit enter. Then I hit “b” to boot it.
    One it came up, I went to Applications->Accessories->Terminal
    I then typed: sudo nano /boot/grub/menu.lst
    I then scrolled to the bottom, and edited the two “Ubuntu 8.04 kernel” entries and added vga=491 to the end of their kernel lines.
    I then hit Control-X, followed by “Y”, then “enter” to save the file.
    I then ran: sudo update-grub
    Then I rebooted to check, and it all came up fine.

    Thanks Graham Laverty to 🙂

  2. A instalar o OpenSuse dá o mesmo erro,
    a instalar o Debian não consegue montar o DVD,
    É preciso um curso para trabalhar com produtos não M$ no Virtual PC
    Boa dica!!

  3. Everything is very open with a very clear clarification of the
    challenges. It was really informative. Your website is very useful.
    Many thanks for sharing!

  4. You really make it appear so easy together with your presentation however I
    find this matter to be really something that I think I’d never understand.

    It sort of feels too complex and very broad for me.

    I am having a look ahead in your subsequent put up, I’ll try
    to get the dangle of it!
