profissionais do hi linux = O
Eu tinha Ubuntu 12.04 3.5.0-23-dual boot genérico com win7. mas havia um problema para usar o ati / radeon fglrx no meu sistema, então eu decidi fazer o downgrade do kernel (porque esse driver trabalhando com o kernel < = 3.4 ).
Instalei o linux-image.3.2.0-23-generic e o linux-image.3.2.0-24-generic no meu sistema, e usei o sudo update-grub para adicionar esses kernels ao grub boot loader e a saída mostrou todos os kernels adicionados ao boot loader.
após o reinício, havia apenas 3.5.0-23 no boot loader, então eu pensei que se eu desinstalar o grub 3.5.0-23 pode carregar outros kernels (estou tendo vergonha = [] .Eu desinstalei linux-image-3.5.0.23generic via synaptic e após o reinício há apenas estas opções no carregador de inicialização do grub:
memtest
win7
Eu usei o live usb para obter essas informações:

não há nada em / boot .
1-esses kernles (3.2.0.23 e 3.20.24) existem no meu sistema?
2_se eles estiverem no meu sistema, como posso adicioná-los ao grub e usá-los?
3-Existe uma maneira de obter o kernel 3.5.0.23 de volta?
Eu li tópicos semelhantes antes, mas eu não quero reinstalar o Ubuntu. por favor me ajude. : '(
