Installing ubuntu9.04,i can't log in any OS(XP and ubuntu)

[iwanderer]

I first installed ubuntu9.04 under XP sp3 using WUBI.Then i uninstall it .After that i install ubuntu9.04 on hardware C:/ ,not using LiveCD.
Finishing the installation,it need to be restart.Then neither XP nor ubuntu i can log in,because there are not OS lists for me to choose,and just only can enter MenTest 86.
Now i use LiveCD to mount the hardware,check the menu.lst.
The following are the 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 use 'savedefault' 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 3

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

# Pretty colours
#color cyan/blue white/blue

## 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
# password --md5 $1$gLhU0/$aW78kHK1QfV3P2b2znUoe/
# password topsecret

# makeactive
# chainloader +1

# title Linux
# root (hd0,1)
# kernel /vmlinuz root=/dev/hda2 ro

# Put static boot stanzas before and/or after AUTOMAGIC KERNEL LIST

### BEGIN AUTOMAGIC KERNELS LIST
## lines between the AUTOMAGIC KERNELS LIST markers will be modified
## by the debian update-grub script except for the default options below

## DO NOT UNCOMMENT THEM, Just edit them to your needs

## ## Start Default Options ##
## 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.
## e.g. kopt=root=/dev/hda1 ro
## kopt_2_6_8=root=/dev/hdc1 ro
## kopt_2_6_8_2_686=root=/dev/hdc2 ro
# kopt=root=UUID=c54efb99-1264-4e56-956b-24cc1c35b50f ro

## default grub root device
## e.g. groot=(hd0,0)
# groot=c54efb99-1264-4e56-956b-24cc1c35b50f

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

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

## additional options to use with the default boot option, but not with the
## alternatives
## e.g. defoptions=vga=791 resume=/dev/hda5
# defoptions=quiet splash

## should update-grub lock old automagic boot options
## e.g. lockold=false
## lockold=true
# 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
## alternative kernel options
## e.g. howmany=all
## howmany=7
# howmany=all

## specify if running in Xen domU or have grub detect automatically
## update-grub will ignore non-xen kernels when running in domU and vice versa
## e.g. indomU=detect
## indomU=true
## indomU=false
# indomU=detect

## 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
# updatedefaultentry=false

## should update-grub add savedefault to the default options
## can be true or false
# savedefault=false

## ## End Default Options ##

wubi我不怎么懂，帮你顶下。看其它朋友有什么办法。或者你用LiveCD重装哥伦布试试。

No No No, you misunderstood my words. I install on the hardware by storing the ubuntu9.04.iso on the C:/.

[fvwmnet]

what??

[iwanderer]

what??

Sorry i can't type Chinese...
Any questions?

[iwanderer]

From the pictures,you can find there are 5 devices: dev/sda1 is my Xp system, dev/sda5 & dev/sda6 are my D,E devices on the XP,dev/sda7 is ubuntu 9.04 that i install last night;the last one is my mobile hardware.
now i don't want to lose my XP system.

So ,how to rebuild the menu.lst to reboot the two systems?
And i found that under /boot the file"vmlinuz" is missing..
But i can't paste it from the Live CD.It said that i dont have the permission:

打开一个终端，在 Applications-Accessories-Terminal
然后输入以下命令
sudo -i
mount /dev/sda7 /mnt
echo "title windows" >> /mnt/boot/grub/menu.lst
echo "rootnoverify (hd0,0)" >> /mnt/boot/grub/menu.lst
echo "chainloader +1" >> /mnt/boot/grub/menu.lst

希望尽早解决。

没有自动添加 windows 启动项是因为你把 iso 放在 c 盘， c 盘在安装时候被识别为光驱了，按 10 楼手动添加启动项就行了。
没有 ubuntu 启动项是因为没有安装任何内核，原因不明，但一定是安装时哪里出错了。
