提问者采纳
电脑是能打开的我去,grub?还有?你电脑之前是不是用的Linux
你电脑是不是之前用过什么红旗Linux、雨林木风Linux或者Ubuntu之类的系统啊?
现在该咋办啊 着急的不行
没什么大不了的。有win7安装盘吗?
没有&#128557;
那你是怎么安装win7的?
我是从网上下载的一键安装的
以前下载一键安装 装过xp很快的
本来就快安装好了
重启了一下就成这样 不动了
那你有U盘吗?懂改BIOS启动顺序吗?
可是u盘上也没有系统包啊
不需要系统包,你去做一个大白菜pe然后启动电脑,用里面的系统启动修复工具修一下就行。
怎么做大白菜pe那是什么?
你百度下大白菜pe就知道了。官网有教程。看不懂再告诉我。
可是现在电脑开不开啊
哦,那不行了。你电脑的win7装在哪个盘了?
那么,你启动到这个界面后,尝试依次输入下以下这些命令:find --set-root &#47;bootmgr(回车)chainloader &#47;bootmgr(回车)boot(回车)正常情况下,应该就可以了。 实在不行你再试试输入这个:root (hd0,1)(回车)chainloader &#47;bootmgr(回车)boot(回车)
输入完这些后按什么
我输完怎么没反应
后面告诉你按回车了啊。记住输完一条按一下。
可是电脑没有重启也没有反应啊 只是显示我输入的英语
不可能的,输完一条后按回车至少应该返回错误信息不会什么都没有的。
是输完一条回车一下出来一段英语 但是全输完了 也没有开机啊
输完就是这样
唉,你要是懂grub就好办了。既然这样,我推荐你去找一个师傅帮你重装一下。
我输的不对吗?还是哪里不对啊
你先输第一段。
把第一条命令换成如下:root (hd0,0)(回车)其他不变。
刚才搜到一个按f5的说法
果然打开了电脑
但是重启还是那样
打开就行。接下来安装完后,下载一个bootsect.exe,放到C盘,用开始菜单打开命令提示符(右键单击以管理员身份运行,出现窗口点允许),然后输入以下命令:c:&#92;bootsect &#47;nt60 sys &#47;mbr引导就修复了,然后再也不会出现了。没有文件我给你。
又打不开了
他刚才说激活完成了
唉 你要是早两分钟发就好了
现在成这样的了
你再按刚才的f5说法试试。
红色背景的吗
windows with slic loader(default)。这是激活的系统。话说,我忙活一晚上了净帮你了,别人都没来得及帮。
我会记住你的。兄弟
实在感谢你
我选了第一项 然后呢
进去了吗?
选了第一项 成这样了
选第四项。
又成这样了
用f5的方法
那你就选windows without loader那一项。得加快速度了,不然我就只能明天中午帮你了。
我选了 然后呢
现在怎么样,进去了吗?
现在显示什么了?
不行挨个试一遍,反正不会损坏电脑的。
进最后一项,输入下列命令试试吧:search 空格 --set-root 空格 &#47;bootmgr回车chainloader 空格 &#47;bootmgr 回车boot 回车只能帮你到11点,过了点我也得睡了。
真的非常谢谢
修好了吗?我这边是44.
把那个search改成find试试(我去,这回答可以申请追问次数最多的吉尼斯世界纪录了!?
用f5方法呢?
按了 没反应
重开机,打开就按f5
那样直接秒进来
现在f5已经变成这个的指令了
唉,倒霉的grub折腾死多少新手啊……确定是C盘安装win7吗?
我记得我选的是
这……你解决了吗?没解决的话接受提问者采纳我受之有愧啊……
我怕我忘了
这……好吧。咱们先睡觉,我明天12点半~2点在线,到时你来问我。
我找个装系统的人 能给我解决吗
我回来了,你找个装系统的的确能给你解决问题,但是却不能保护住你的数据。
d 盘 e盘 f 盘也会没有?
这个不会的。不过我正在用虚拟机模拟你的环境来解决问题
有效果吗?
有效果。按我说的做。(你可回来了啊~)先在那个红色界面选最后一项,然后输入find (空格)&#47;bootmgr(回车)把返回的信息给我,不用截图。
选最后一项是按e还是按回车?
回车。(我先吃个饭)
输完后按完回车
出现 Error27:Unrecognized command
我在线翻译了一下 是错误27 不可识别的命令的意思
输入下 root 空格(hd0,0)回车试试
又出现一行新的grub
其实上一条出现错误是我没按find后面的空格
然后输入 chainloader 空格 &#47;bootmgr
出现错误13
第一行的find输完后有没有什么返回呢
直接出现一行新的grub
那你用 search空格 &#47;bootmgr
按esc然后一直按f5
倒数完5秒进入这个
按下回车,然后选最后一项。最悲惨的情况你要想好:可能grub也出了问题。
那该怎么办
如果grub也出了问题,那么我在这边也帮不了你,你就只能去找师傅修了。现在你重启下电脑,选最后的那个 grub command line(我感觉这是我最失败的回答了55555)
是从装一遍系统吗
他应该会给你重装一遍,不过如果你告诉他是引导问题的话,他应该只会给你修引导就好不会重装。
我选了最后一项了 然后呢
你输入下help,截个图给我看返回的数据
你试试输入find --set-root 空格&#47;bootmgr回车试试(别忘了空格与回车,字符也不要打错)
grub出问题了,你找师傅修吧。记住让他把引导修回来不是重装

而且系统本身也比ghost系统安全得多,建议用原版安装盘进行安装,这样就不会再有这种情况发生了这是用ghost安装盘安装的系统出现的常见问题
那现在怎么才能启动电脑啊
用u盘启动电脑,把启动作用设为一个100mb大小的分区,其它都关闭(active,作用),保存重启
能讲详细点吗?帮帮我 真的很着急
我不太懂怎么用u盘启动
还有启动之后该做什么就能正常
你有带分区软件的可启动电脑的u盘吗?
大白菜,天意,等等
光盘也行,只要能启动电脑,进行分区操作的就行
都没有啊&#128557;
这是哪里导致的问题呀 以前用这个装过xp挺好用的呀
那就需要搞到一个,光盘的最快
win7的启动机制与xp的不一样
你现在系统也回不去了吧
ghost安装的win7是最不稳定的,往往还天生带毒、肉鸡系统
如果我等明天找一个专业做系统的人来给我从做一个win7系统
能做吗还 不会因为我刚才的操作全都弄得不行了吧
只要专业,就没问题楼主,听我一句吧——不要再用 GHOST 安装系统了!还有:像我之前说的,只要用大白菜、天意等u盘启动,设置那个100Mb的分区设为作用,其它都关闭(active,作用),保存重启,就ok了。那些 Linux Loader (就是输入的那一大堆命令的) 在 Windows 的 GHOST 里是无效的... 晚安,您那
从新安装系统,安装前先把C盘格式化
可是现在打不开了啊
电脑打不开了
你用什么装系统
网上下载的 win7一键安装
安装盘还是U盘?
就是直接下载到硬盘上 一点就好的那种
你进入映像以后用格式化工具直接格式化C盘,格式化以后再安装系统就OK了

官方公共微信GRUB Manual - Error messages reported by GRUB
Go to the , , ,
section, .
This chapter describes error messages reported by GRUB when you
encounter trouble. See section , if your problem is
specific to the grub shell.
The general way that the Stage 1 handles errors is to print an error
string and then halt. Pressing CTRL-ALT-DEL will
The following is a comprehensive list of error messages for the Stage 1:
Hard Disk Error
The stage2 or stage1.5 is being read from a hard disk, and the attempt
to determine the size and geometry of the hard disk failed.
Floppy Error
The stage2 or stage1.5 is being read from a floppy disk, and the attempt
to determine the size and geometry of the floppy disk failed. It's listed
as a separate error since the probe sequence is different than for hard
Read Error
A disk read error happened while trying to read the stage2 or stage1.5.
Geom Error
The location of the stage2 or stage1.5 is not in the portion of the disk
supported directly by the BIOS read calls.
This could occur because the
BIOS translated geometry has been changed by the user or the disk is
moved to another machine or controller after installation, or GRUB was
not installed using itself (if it was, the Stage 2 version of this error
would have been seen during that process and it would not have completed
the install).
The general way that the Stage 1.5 handles errors is to print an error
number in the form Error num and then halt. Pressing
CTRL-ALT-DEL will reboot.
The error numbers correspond to the errors reported by Stage
2. See section .
The general way that the Stage 2 handles errors is to abort the
operation in question, print an error string, then (if possible) either
continue based on the fact that an error occurred or wait for the user to
deal with the error.
The following is a comprehensive list of error messages for the Stage 2
(error numbers for the Stage 1.5 are listed before the colon in each
description):
1 : Filename must be either an absolute filename or blocklist
This error is returned if a file name is requested which doesn't fit the
syntax/rules listed in the section .
2 : Bad file or directory type
This error is returned if a file requested is not a regular file, but
something like a symbolic link, directory, or FIFO.
3 : Bad or corrupt data while decompressing file
This error is returned if the run-length decompression code gets an
internal error. This is usually from a corrupt file.
4 : Bad or incompatible header in compressed file
This error is returned if the file header for a supposedly compressed
file is bad.
5 : Partition table invalid or corrupt
This error is returned if the sanity checks on the integrity of the
partition table fail. This is a bad sign.
6 : Mismatched or corrupt version of stage1/stage2
This error is returned if the install command is pointed to incompatible
or corrupt versions of the stage1 or stage2. It can't detect corruption
in general, but this is a sanity check on the version numbers, which
should be correct.
7 : Loading below 1MB is not supported
This error is returned if the lowest address in a kernel is below the
1MB boundary. The Linux zImage format is a special case and can be
handled since it has a fixed loading address and maximum size.
8 : Kernel must be loaded before booting
This error is returned if GRUB is told to execute the boot sequence
without having a kernel to start.
9 : Unknown boot failure
This error is returned if the boot attempt did not succeed for reasons
which are unknown.
10 : Unsupported Multiboot features requested
This error is returned when the Multiboot features word in the Multiboot
header requires a feature that is not recognized. The point of this is
that the kernel requires special handling which GRUB is likely unable to
11 : Unrecognized device string
This error is returned if a device string was expected, and the string
encountered didn't fit the syntax/rules listed in the section .
12 : Invalid device requested
This error is returned if a device string is recognizable but does not
fall under the other device errors.
13 : Invalid or unsupported executable format
This error is returned if the kernel image being loaded is not
recognized as Multiboot or one of the supported native formats (Linux
zImage or bzImage, FreeBSD, or NetBSD).
14 : Filesystem compatibility error, cannot read whole file
Some of the filesystem reading code in GRUB has limits on the length of
the files it can read. This error is returned when the user runs into
such a limit.
15 : File not found
This error is returned if the specified file name cannot be found, but
everything else (like the disk/partition info) is OK.
16 : Inconsistent filesystem structure
This error is returned by the filesystem code to denote an internal
error caused by the sanity checks of the filesystem structure on disk
not matching what it expects. This is usually caused by a corrupt
filesystem or bugs in the code handling it in GRUB.
17 : Cannot mount selected partition
This error is returned if the partition requested exists, but the
filesystem type cannot be recognized by GRUB.
18 : Selected cylinder exceeds maximum supported by BIOS
This error is returned when a read is attempted at a linear block
address beyond the end of the BIOS translated area. This generally
happens if your disk is larger than the BIOS can handle (512MB for
(E)IDE disks on older machines or larger than 8GB in general).
19 : Linux kernel must be loaded before initrd
This error is returned if the initrd command is used before loading a
Linux kernel. Similar to the above error, it only makes sense in that
case anyway.
20 : Multiboot kernel must be loaded before modules
This error is returned if the module load command is used before loading
a Multiboot kernel. It only makes sense in this case anyway, as GRUB has
no idea how to communicate the presence of location of such modules to a
non-Multiboot-aware kernel.
21 : Selected disk does not exist
This error is returned if the device part of a device- or full file name
refers to a disk or BIOS device that is not present or not recognized by
the BIOS in the system.
22 : No such partition
This error is returned if a partition is requested in the device part of
a device- or full file name which isn't on the selected disk.
23 : Error while parsing number
This error is returned if GRUB was expecting to read a number and
encountered bad data.
24 : Attempt to access block outside partition
This error is returned if a linear block address is outside of the disk
partition. This generally happens because of a corrupt filesystem on the
disk or a bug in the code handling it in GRUB (it's a great debugging
25 : Disk read error
This error is returned if there is a disk read error when trying to
probe or read data from a particular disk.
26 : Too many symbolic links
This error is returned if the link count is beyond the maximum
(currently 5), possibly the symbolic links are looped.
27 : Unrecognized command
This error is returned if an unrecognized command is entered into the
command-line or in a boot sequence section of a configuration file and
that entry is selected.
28 : Selected item cannot fit into memory
This error is returned if a kernel, module, or raw file load command is
either trying to load its data such that it won't fit into memory or it
is simply too big.
29 : Disk write error
This error is returned if there is a disk write error when trying to
write to a particular disk. This would generally only occur during an
install of set active partition command.
30 : Invalid argument
This error is returned if an argument specified to a command is invalid.
31 : File is not sector aligned
This error may occur only when you access a ReiserFS partition by
block-lists (e.g. the command @command{install}). In this case, you
should mount the partition with the `-o notail' option.
32 : Must be authenticated
This error is returned if you try to run a locked entry. You should
enter a correct password before running such an entry.

那有没有可能硬盘坏了呢?
我不是说了么,你命令里少了个空格,所以错误了
哦 好吧 知道了
还是打不开啊
有没有可能是把引导器删了
有这个可能找个PE进去恢复一下引导吧
要怎么安装 进不了系统
你输入find回车我看看有几个设备
我勒个去,一个有效分区都没有啊
看起来被删的不止是引导器
是不是把硬盘给删了
不排除硬盘故障或者分区被删除
要咋样恢复
恢复不了,重新装系统
可以自己装么
可以,你得有可以用于启动的系统U盘或者光盘
手机可以不
那自己刻的XP光盘呢
要是实在不行,还是拿电脑城搞吧

出门在外也不愁win7电脑开机显示error 27:unrecognized command是怎么回事?_百度知道
win7电脑开机显示error 27:unrecognized command是怎么回事?
电脑开机不能启动,显示屏上说:press esc for recovery menu.然后下面一行是:grub&.后面一个光标一直闪烁。随便输个键就出现:error 27 :unrecognized command.意思就是叫您恢复系统,这是因为系统引导丢失或者损坏所致,如果有备份,复制一个引导文件到C盘下也可以解决,一般是OEMKY 之类的引导文件。 联想预装系统有个隐藏分区,你用Ghost,装机不能被认定,最好重新分下区,用正版的win7,这个情况就没有了.ghost版本的win7系统吧,如果这样的话修复起来有点麻烦:用DiskGeniusV3.2.2010标准版的清除保留扇区命令,把To start your Lenovo Rescue and Recovery program,Press F11信息去掉后,再用Mbrfix工具修复系统引导。在winpe的命令提示符下,进入Mbrfix目录,执行:MbrFix &#47;drive 0 fixmbr &#47;win7 &#47;yes重启电脑即可。或者在grub中输入 help ,有命令列表;输入以下命令:
find --set-root &#47;ntldr
chainloader &#47;ntldr
boot就可以进入winxp的引导;或者,
find --set-root &#47;bootmgr
chainloader &#47;bootmgr
boot就可以进入win7 , vista 的引导;或者,
chainloader (hd0,0)+1
boot就可以从第一个硬盘第一个主引导区引导。 或者,
find --set-root &#47;peldr
chainloader &#47;peldr
boot可以引导winpe,如果不行,试试或者,
find --set-root &#47;avldr
chainloader &#47;avldr
boot还不能引导winPE,那就想其它办法引导winPE吧!重新恢复主引导区,可以:用光盘进DOS,使用fdisk &#47;mbr可以恢复主引导区;或者,进入windowsXP的故障恢复台,输入命令:fixmbr也可以恢复主引导区或者,进入 DOS 或 winPE 或 winXP 后,使用软件恢复主引导区,都行。
