Ubuntu 10 no Wubi e Windows 7 Profissional 64 bits - Erro na instalção

[f.viana]

Tenho um Windows 7 Professional 64 bits e resolvi instalar o Ubuntu 10 32 bits através do Wubi, mediante arquivo ISO. Separei uma partição limpinha para ele. No início, tudo correu bem. Os arquivos foram carregados e instalados, totalmente. Mas, na reinicialização, quando escolhi o Ubuntu naquela tela de boot do Windows, apareceu um erro que travou o micro. Fiz todo o processo novamente e o mesmo erro apareceu, sendo mostrada a seguinte mensagem:


init: plymouth min process (440) killed by KILL signal
Init: ureadahead main process (439) killed by KILL signal
exec: 5: mountall: Input/output error
