求助：双硬盘（sata、pata各一个）grub不能引导winxp！

[cqg]

本人一块320g sata硬盘装winxp，一块pata48g硬盘（sdb）装ubuntu 8.10，先安装xp后装ubuntu。grub安装在48g硬盘上 ，安装完成后，进入ubuntu正常，而winxp不能加入。
下面是fdisk -l的数据：

请问是何处出问题，该如何修改？

[ptptptptptpt]

你改过硬盘的次序吗？？bios 中哪块硬盘作为第一硬盘？？

[cqg]

48g的pata硬盘为第一硬盘

[adagio]

XP那里改成这样试试

代码： 全选

title		Windows XP
root		(hd1,0)
map		(hd0) (hd1)
map		(hd1) (hd0)
chainloader	+1
savedefault

[ptptptptptpt]

XP那里改成这样试试

代码： 全选

title		Windows XP
root		(hd1,0)
map		(hd0) (hd1)
map		(hd1) (hd0)
chainloader	+1
savedefault

如果这样还不行，再试试

代码： 全选

title		Windows XP
root		(hd2,0)
map		(hd0) (hd2)
map		(hd2) (hd0)
chainloader	+1
savedefault

ps，48 G 的容量不多见啊，一般都是 40 60 。。

[cqg]

48g的是我的一个60g硬盘维修坏道后才变成48g,多谢楼上各位指点，回去再试试看。


都试过了，还是不行

[pjw8243]

跟LZ一样，现在每次都进bios切换系统,什么时候搞定了通知一声

[pjw8243]

我启动成功了，
title Windows XP
map {hd0} {hd1}
map {hd1} {hd0}
chainloader(hd1,0) +1

[pjw8243]

我启动成功了，
title Windows XP
map {hd0} {hd1}
map {hd1} {hd0}
chainloader(hd1,0) +1

[cqg]

改来改去，启动winxp时就一直停在【starting up.....】这儿，这种情况是不是map指令没有成功，winxp认为自己不是安装在第一硬盘，而不能启动？？

[adagio]

如果你的XP引导文件的确位于这里的话（看看这个分区里是否有一个ntldr文件）

代码： 全选

/dev/sda1 * 1 1275 10241406 7 HPFS/NTFS

那么使用5楼提供的两种写法，其中之一肯定可以启动

如果还是不行的话，再确定一下你的grub会不会是装到了320G那个硬盘，如果是的话，应该写成这样

代码： 全选

title      Windows XP
root      (hd0,0)
chainloader   +1
savedefault
