再线等：刚刚安装ubuntu 7.04 ,却不能启动。

cyhwy

启动时好长时间不动
最后显示失败：/bin/sh:can’t access tty; job control turn off
(initramfs)

修改menu.lst

添加 irqpoll

也不行。

下面是menu.lst
# menu.lst - See: grub(8), info grub, update-grub(8)
#            grub-install(8), grub-floppy(8),
#            grub-md5-crypt, /usr/share/doc/grub
#            and /usr/share/doc/grub-doc/.

## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not change this entry to 'saved' or your
# array will desync and will not let you boot your system.
default                0

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout                10

## hiddenmenu
# Hides the menu by default (press ESC to see the menu)
#hiddenmenu

# Pretty colours

## password ['--md5'] passwd
# If used in the first section of a menu file, disable all interactive editing
# control (menu entry editor and command-line)  and entries protected by the
# command 'lock'
# e.g. password topsecret

## default kernel options
## default kernel options for automagic boot options
## If you want special options for specific kernels use kopt_x_y_z
## where x.y.z is kernel version. Minor versions can be omitted.

##      kopt_2_6_8_2_686=root=/dev/hdc2 ro

## Setup crashdump menu entries
## e.g. crashdump=1
# crashdump=0

## default grub root device
## e.g. groot=(hd0,0)
# groot=(hd0,8)

## should update-grub create alternative automagic boot options
## e.g. alternative=true

## should update-grub lock alternative automagic boot options
## e.g. lockalternative=true

## additional options to use with the default boot option, but not with the

# lockold=false

## Xen hypervisor options to use with the default Xen boot option
# xenhopt=

## Xen Linux kernel options to use with the default Xen boot option
# xenkopt=console=tty0

## altoption boot targets option
## multiple altoptions lines are allowed
## e.g. altoptions=(extra menu suffix) extra boot options
##      altoptions=(recovery) single
# altoptions=(recovery mode) single

## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the

## should update-grub create memtest86 boot option
## e.g. memtest86=true
##      memtest86=false
# memtest86=true

## should update-grub adjust the value of the default booted system
## can be true or false

到底如何解决？？？

cyhwy

刚才试了，把root=UUID=eff2ffae-c527-44b1-bac1-1695e682aacf 替换成
root=/dev/hda9

也不行

baoshaojing

你的应该是硬盘安装的吧。我的也出现过这样的情况，不过查了好多的资料都没有解决，google上搜索英文的也没有找到解决之道，所以啊，还是用这种方法重新安装一次吧

谢谢，不是用硬盘安装的，使用寄来的光盘，
光盘能正常启动，安装完就成这样。

baoshaojing

本人对于该问题也是很不解之，要不你就按照那个方法再安装一次——呵呵，如果那个引导包比较难下载我可以发到你的邮箱，剩下的我也帮不了忙了。好像是在查找什么文件的时候出现了错误。呵呵。

cyhwy

可是，没有比较详细的安装步骤

baoshaojing

你下载那个引导包，解压之后，里面有个readme。看完之后你就明白了。所有的安装步骤都在那个readme当中了
