Ubuntu启动时停留在选择系统的那个页面。
选择第一个ubuntu with linux2.6.28-8-server后 出现一段字符,但不动了,
字符最后一个是(initramfs)
在后面输入exit后,才能继续启动
暂停页面最后显示代码是
Gave up waiting for root device . Common problems:
-boot args (cat /proc/cmdline)
-check rootdelay=(did the system wait long enough?)
-check root=(did the system wait for the right device?)
-missing modules ( cat /proc/modules;ls /dev)
ALERT /dev/disk.by-uuid/9d77fcd2-5fc1-419d-939c-af16be94fd34 does not exist.
Dropping to a shell!
BusyBox v1.17.1(Ubuntu 1:1.171-10ubuntu1) built-in shell (ash)
Enter “help” for a list of built-in commands.
(initramfs)
解决方法:
增加rootdelay参数。利用命令sudo vi /boot/grub/menu.lst修改menu.lst的内容为:Kernel /boot/vmlinuz-2.6.27-7-server rootdelay=90 root=UUID=596db294-4759-4f2c-991b-f8be2931a56a ro quiet。再次重启.
原因:
rootdelay设置的时间太短,导致系统还没有正常加载完设备驱动就已经开始寻找root分区,而导致找不到/root分区。
