vwinxp无法启动了（在线等）急啊！！！

kaizen · 发表于 2004-7-4 13:22:45

就多:
$ sfdisk -d /dev/hda
Warning: extended partition does not start at a cylinder boundary.
DOS and Linux will interpret the contents differently.
不是吗?
怎样出去报错?
除去了就行了吗?

kaizen · 发表于 2004-7-4 13:31:13

我用sfdisk -d /dev/hda 后显示如下信息:
Warning: extended partition does not start at a cylinder boundary.
DOS and Linux will interpret the contents differently.
# partition table of /dev/hda
unit: sectors

/dev/hda1 : start= 63, size= 12369987, Id=1b
/dev/hda2 : start= 12370050, size= 43728930, Id= f
/dev/hda3 : start= 56098980, size= 20996955, Id=83, bootable
/dev/hda4 : start= 77095935, size= 1060290, Id=82
/dev/hda5 : start= 12370113, size= 21784077, Id= b
/dev/hda6 : start= 34154253, size= 21944727, Id= b
然后该怎么办?

GGGO · 发表于 2004-7-4 14:59:42

照那篇英文文章的话是：
sfdisk -d /dev/hda > MyPartitionTable.txt
编辑MyPartitionTable.txt使之成为
[code:1]
# partition table of /dev/hda
unit: sectors

/dev/hda1 : start= 63, size= 16771797, Id= 7, bootable
/dev/hda2 : start= 16771860, size=217632555, Id= f
/dev/hda3 : start= 0, size= 0, Id= 0
/dev/hda4 : start= 0, size= 0, Id= 0
/dev/hda5 : start= 16771923, size=104856192, Id= 7
/dev/hda6 : start=121628178, size=112776237, Id= 7
[/code:1]
也就是删掉
Warning: extended partition does not start at a cylinder boundary.
DOS and Linux will interpret the contents differently.
就行了。

kaizen · 发表于 2004-7-4 15:27:56

就这样就行了?在哪里把
Warning: extended partition does not start at a cylinder boundary.
DOS and Linux will interpret the contents differently.
删除掉阿?不回是在MyPartitionTable.txt里面吧

kaizen · 发表于 2004-7-4 16:39:30

不会吧,这样我的windows就重新启动了?在MyPartitionTable.txt里面删除后大不了改变了该文本文件,对系统会产生影响吗?不会这么简单吧.

cee1 · 发表于 2004-7-4 16:57:22

再用命令(linux下)
cat MyPartitionTable.txt | sfdisk --no-reread -H255 /dev/hda
这时把txt的内容输入到命令中

kaizen · 发表于 2004-7-4 17:08:29

输入/root/mpt.txt信息如下
[root@Kaizen root]#  cat /root/mpt.txt
# partition table of /dev/hda
unit: sectors

/dev/hda1 : start=    63, size= 12369987, Id=1b
/dev/hda2 : start= 12370050, size= 43728930, Id= f
/dev/hda3 : start= 56098980, size= 20996955, Id=83, bootable
/dev/hda4 : start= 77095935, size=  1060290, Id=82
/dev/hda5 : start= 12370113, size= 21784077, Id= b
/dev/hda6 : start= 34154253, size= 21944727, Id= b
*******
输入sfdisk --no-reread -H255 /dev/hda后出现下面信息现在我该怎么办
[root@Kaizen root]# sfdisk --no-reread -H255 /dev/hda

/dev/hda1 : (这里我该输入什么?)

**********************************

kaizen · 发表于 2004-7-4 17:16:37

在/dev/hda1后我输入start= 63, size= 12369987, Id=1b(在txt文件里得来的)出现下面信息
/dev/hda1 :start= 63, size= 12369987, Id=1b
trailing junk after number

/dev/hda1 :

这是怎么回事,不是把txt里面的内容输入就行了吗?

狂客 · 发表于 2004-7-4 17:54:42

你的 Windows 是装在哪个区？

如果是 C 盘，那么就不是 (hd0,4) 而应该是 (hd0,0)，修改 /boot/grub/grub.conf
相应的语句试试。

kaizen · 发表于 2004-7-4 18:06:33

不行那样后能看见windows启动时的滚动条但是在等录界面前就报错重气了
我cat /root/mpt.txt | sfdisk --no-reread -H255 /dev/hda后出现如下信息

现在怎么办?

kaizen · 发表于 2004-7-4 19:53:11

为什么在我的grub.conf里面有下面的信息
title Other
rootnoverify (hd0,4)
chainloader +1
有人说rootnoverify (hd0,0)才能正常启动
我改了后能看见winxp启动时的滚动条,但是后面就是两条错误信息,然后就重起了(这是在用cat /root/mpt.txt | sfdisk --no-reread -H255 /dev/hda前)现在我都不敢关机了因为用了cat /root/mpt.txt | sfdisk --no-reread -H255 /dev/hda后
有这样的内容:
Re-reading the partition table ...
BLKRRPART: 设备或资源忙
The command to re-read the partition table failed
Reboot your system now, before using mkfs

If you created or changed a DOS partition, /dev/foo7, say, then use dd(1)

(See fdisk( 8 ).
一看就知道有错误了这么办啊?
**************************************急啊**********************************

GGGO · 发表于 2004-7-4 20:52:22

你理解错了。干脆我把过程写出来吧。
1、sfdisk -d /dev/hda > MyPartitionTable.txt
2、编辑MyPartitionTable.txt文件，去掉开始的错误信息，保存。
3、cat MyPartitionTable.txt | sfdisk --no-reread -H255 /dev/hda
注释：上面的命令打全再回车。就是把MyPartitionTable.txt的内容当作sfdisk的输入。
这个是那篇英文文章写的。实际效果我不清楚，不知道能否行得同？

kaizen · 发表于 2004-7-4 21:51:05

为什么结果是这样的?没有成功吗?

这么办?

kaizen · 发表于 2004-7-4 22:48:38

我用cat MyPartitionTable.txt | sfdisk --no-reread -H255 /dev/hda 把改后的txt中的内容写到命令后(就是把"警告"去处后的TXT)

但是用命令sfdisk -d /dev/hda > MyPartitionTable.txt后发现txt的内容还是和没改一样

我想应该不是直接把"警告"删掉就完事了吧,会不会是要修改其内容一直到用sfdisk -d /dev/hda > MyPartitionTable.txt命令后的输出结果没有错误为止?
