grub问题求解？？

yttlovezxx

1：安装fc2的时候把vmlinuz和initrd.img放到了/dev/hda10（Hiweed Debian）
由于grub里面加了一句：savedefault;boot;然后安装完后，启动debian的时候总是启动fc2的安装画面，怎么能恢复以前的debian启动呢？！我删了vmlinuz和initrd.img后也是启动fc2的安装画面/？？？       
-----------------------------------------------------------------------------------
2：删了redhat的boot分区的initrd和vmlinuz后不能找到/分区和加载有的模块失败，可是我又做了一个链接后，还是显示那样？？
怎么办？？？
启动出现如下信息：

VFS：cannot open root device "/dev/hda7 unknown block(0,0)

please append a correct "root=" boot option

kernel panic VFS: unable to mount root fs on unknown-block(0,0)


怎么解决？

1。是grub 画面还是整个其他过程，你的grub 在写的？

2。软链接？在同一个文件系统吗？

The menu.lst of hiweed debian:

# menu.lst - See: grub(, info grub, update-grub(
#            grub-install(, grub-floppy(,
#            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'.           
default                5

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout                100

# 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/

估计我已经找到答案了，可能是FSTAB文件有问题吧！！！
