安装 ubuntu 12 后，Windows 7 不再显示在我的 grub 中，您能帮忙吗？
我已经完成了 grub-update 等。
这是我的启动脚本信息

# #################### LILO global section ######################
# With all newer systems (until year 2004) you can use the RAM
# above 15 MB. This option allows the use of this range of RAM.
#large-memory
# With all newer systems you can boot from any partition on disks
# with more than 1024 cylinders. This option allows the use of
# partitions above 1024 cylinders.
lba32
# Specifies the boot device. This is where Lilo installs its boot
# block. It can be either a partition, or the raw device, in which
# case it installs in the MBR, and will overwrite the current MBR.
# With newer kernel you should use the ID of the boot device, which
# can be found here: /dev/disks/by-id/ata*.
#boot = /dev/sdb
boot = /dev/disk/by-id/ata-Hitachi_HDS722020ALA330_JK1171YAGVD55N
# This option may be needed for some software RAID installs.
#raid-extra-boot = mbr-only
# Enable map compaction. This tries to merge read requests for
# adjacent sectors into a single read request. This drastically
# reduces load time and keeps the map smaller. Using 'compact'
# is especially recommended when booting from a floppy disk.
# It is disabled here by default because it doesn't always work.
#compact
# Set the verbose level for bootloader installation. Value range:
# 0 to 5. Default value is 0.
#verbose = 1
# Specifies the location of the map file. Lilo creates the (sector)
# map file of direct sector addresses which are independent of any
# filesystem.
map = /boot/map
# ---------------------------------------------------------------
# Specifies the menu interface. You have the choice between:
# text: simple text menu with black background and white text
# menu: configurable text menu with background and text colors.
# bmp: graphical menu with 640x480 bitmap background.
install = menu
# A) Customized boot message for choice 'text'.
# For the simple text menu you can set an extra message in the
# created file. Its text will be displayed before boot prompt.
#message = /boot/message.txt
# B) Configuration of the scheme for choice 'menu'.
# Use following coding: <text>:<highlight>:<border>:<title>
# The first character of each part sets the text frontcolor,
# the second character of earch part sets the text backcolor,
# an upper-case character sets bold face text (frontcolor).
# i.g. 'menu-scheme=wm:rw:wm:Wm'. Possible colors:
# k=black, b=blue, g=green, c=cyan, r=red, m=magenta, y=yellow, w=white.
menu-scheme = Wb:Yr:Wb:Wb
#menu-title = " DESDEMONA Boot-Manager "
# C) Configuration of the image for choice 'bmp'.
# For the graphical menu you need a bitmap file, which needs a special
# menu configuration in the file header (see: lilo -E). Ideally you
# use one of the delivered images of the lilo package.
# with 16 colors: onlyblue, tuxlogo, inside
# with 256 colors: coffee
# for Debian: debianlilo, debian, debian-de
#bitmap = /boot/tuxlogo.bmp
# ---------------------------------------------------------------

# should wait before booting the first image. LILO doesn't wait if
# 'delay' is omitted or set to zero. You do not see the defined menu.
#delay = 20
# Prompt to start one certain kernel from the displayed menu.
# It is very recommeded to also set 'timeout'. Without timeout boot
# will not take place unless you hit return. Timeout is the number
# of deciseconds (0.1 seconds) after there the default image will
# be started. With 'single-key' alias numbers for each menu line can
# be used.
prompt
timeout = 100
#single-key
# ---------------------------------------------------------------
# Specifying the VGA text mode that should be selected when booting.
# The following values are recognized (case is ignored):
# vga=normal 80x25 text mode (default)
# vga=extended 80x50 text mode (abbreviated to 'ext')
# vga=ask stop and ask for user input: choice of text mode
# vga=<mode> use the corresponding text mode number. A list of
# available modes can be obtained by booting with
# vga=ask' and then pressing [Enter].
# Another way is the use of frame buffer mode. Then the kernel
# will switch from the normal vga text mode (80x25) to the frame
# buffer mode (if frame buffer support is in the kernel):
# vga=0x314 800x600 @ 16 bit
# vga=0x317 1024x768 @ 16 bit
# vga=0x318 1024x768 @ 24 bit
#vga = ask
vga = normal
#vga = 0x317

答案1
你已经挂载了所有硬盘分区了吗？你应该尝试使用以下命令重新安装 grub：
# To view all your partitions
sudo fdisk -l
然后使用以下命令挂载你的 Linux 分区：
# pay attention to the number of your linux partition.
sudo mount /dev/sda5 /mnt
最后：
sudo grub-install --boot-directory=/mnt/boot /dev/sda
然后，重新启动并检查是否有效。修复 grub 后，您可以再试sudo update-grub一次。
