Eu recentemente tive uma queda de energia enquanto logado no 11.04 com o XP rodando no VirtualBox. Quando eu agora tento inicializar, recebo o Disk Boot failure, Insert System disk and Press Enter .
Eu executei um utilitário de disco e tudo parece bem. Eu posso arrancar a partir de um USB ao vivo e navegar pelos arquivos na unidade.
fdisk retorna o seguinte: -

This doesn't look like a partition table
Probably you selected the wrong device.

Partition table entries are not in disk order
Alguma opinião?
