Kernel Panic [Solved] [Решено]

Устанавливаю на ноутбук TOSHIBA M40X-116 gentoo с помощью minimal cd.
При загрузке ядра выдается следующие сообщения:
VFS: Cannot open root device "sda8" or unknown-block(8,8)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,8)
