安装完Ubuntu 9.04启动到grub时出现waiting for loading…后提示找不到root device,然后跳入initramfs,这时如果运行exit可以进入系统说明rootdelay时间太短了,解决办法:sudo vi /boot/grub/menu.lis

安装完Ubuntu 9.04启动到grub时出现waiting for loading…后提示找不到root device,然后跳入initramfs,这时一旦运行exit可以进入系统说明rootdelay时间太短了,解决办法:

sudo vi /boot/grub/menu.lis

可以看到要启动的grub项目:

## ## End Default Options ##

title Ubuntu 9.04, kernel 2.6.28-11-server

uuid c757c22c-b798-433a-b284-8bca8e084406

initrd /initrd.img-2.6.28-11-server

quiet

initrd /initrd.img-2.6.28-11-server

这里在第一项里面的kernel行中加入rootdela=90如下:

## ## End Default Options ##

uuid c757c22c-b798-433a-b284-8bca8e084406

kernel /vmlinuz-2.6.28-11-server root=/dev/mapper/shangri–la-root ro quiet splash rootdelay=90

initrd /initrd.img-2.6.28-11-server

quiet

kernel /vmlinuz-2.6.28-11-server root=/dev/mapper/shangri–la-root ro single

initrd /initrd.img-2.6.28-11-server

title Ubuntu 9.04, memtest86+

uuid c757c22c-b798-433a-b284-8bca8e084406

kernel /memtest86+.bin

quiet

重启后正常。
