grub问题求解？？
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/？？？ :oops::oops::oops::oops:
-----------------------------------------------------------------------------------
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(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'.
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/
# password topsecret

不要直接用这个，我的是有五个菜单的。 估计我已经找到答案了，可能是FSTAB文件有问题吧！！！ :lol:
