Ubuntu6.1 移到第二硬盘适配器无法启动
电脑： Thinkpad T23配置：P3-1.333G/512M/100+40G/14'/WIFI
操作：100G主盘，装Windows2003，工作机；
40G硬盘，装WindowsXP。将40G硬盘放在主盘位置，用PQ适当分区，留最后10G左右未分配空间。用光驱引导，安装Ubuntu6.1, 安装成功. 然后恢复Windows，可实现双系统引导。
问题：将40G 硬盘放进Ultrabay2000硬盘适配器，装在Ultrabay位置，设置该硬盘为第一引导顺序。但Ubuntu无法进入系统；图形界面到滚动条位置即停止不动，硬盘无响应；Recorvery Mode到检测USB鼠标加载驱动之后就不动了，光标闪烁。但该硬盘的WindowsXP可以顺利引导。
如果将该硬盘放回主硬盘位置，又可顺利引导。
请教：各位高手，如果解决该问题。 大致搜了一下，似乎是6.1加入了UUID技术。
但，
从何处下手？请大家指教。 没事过，检查一下/etc/fstab I got exactly the same problem with what you described. Anyone have some ideas? 我也遇到过，这样解决：
http://forum.ubuntu.org.cn/viewtopic.php?t=36813&highlight= 硬盘在系统中的标识跟该硬盘所插的接口的位置相关，硬盘在主盘位置时在系统中的标识是/dev/hda，移到Ultrabay位置时应该变成/dev/hdc。
修改/boot/grub/device.map添加下面一行：
(hd3) /dev/hdc
修改/boot/grub/menu.lst：
把"(hd0"替换成"(hd3"；
把"root=/dev/hda"替换成"root=/dev/hdc"；
/etc/fstab中应该不用修改了，6.10默认是根据分区的UUID标识来挂载相应分区的，UUID不会随硬盘的位置而改变。 谢谢楼上的两位，我试下~
Ubuntu论坛那边真实太冷清了~ 改成hd3不行的。

但是，很奇怪：必须把主硬盘拔下才可以顺利地用slim硬盘启动ubuntu6.0.6，可是，我原先刚修改后都可以同时插上主硬盘和slim硬盘，再用slim硬盘启动的，现在不行了。我估计是bios里boot设备的顺序问题，但怎么也没有搞好。 装6.06的时候碰到过类似问题，后来吧XP放在SLIM上了。 原帖由 shiyg2001 于 2007-2-1 14:14 发表
改成hd3不行的。
我的device.map:
(hd0) /dev/hdc
我的menu.lst:（只需要把root=/dev/hda3，改成root=/dev/hdc3）
# menu.lst - See: grub(8), info grub, update-grub(8) ...
谢谢。
改了看看能不能行。
Linux的东西是有些麻烦。FreeBSD也是这样的情况啊。郁闷ing。 按8楼的改了。
系统崩溃。2003也进不去了。 问题最终解决：
在Ultrabay2000的硬盘里硬盘安装Ubuntu，此类安装说明文件不胜枚举。但要注意一点：
引导文件对应相应的光盘ISO。
我用的是桌面版ISO，与Lice CD相同，在桌面点击Install即可。
另外还需注意的是：
最后一布（6/6），Grub安装位置，要改为HDC。否则主硬盘和第二硬盘作为一个整体被GRUB接管，如果拿开第二硬盘，则无法启动主硬盘的Windows系统。需要重新修复主硬盘的MBR。 用DOS引导盘启动到DOS，Fdisk /mbr即可修复。

chainloader +1 是的,grub要安装到hdc而非hda。
因为这个case里面，linux在hdc，boot区也在hdc。
而grub的stage_1在hda的0面0道1扇区，它将引导start.S(0面0道2扇区）.
然后这个512字节的start.S再去引导stage_1.5，这玩意被放在0面0道3扇区及其以后的大概10k多扇区里。
这个stage_1.5是用来支撑文件系统的，执行之后grub才能认识所谓的分区格式(ext2，ext3，fat...etc)
至于stage_2,就可以作为文件放在文件系统里，位置可以随意了，只要stage_1.5能找到它。
问题是如果把hdc拔除掉，那么也许连stage2都无法找到了，更不用说menu.lst了(这个要是找不到，至少stage_2这个mini OS还能提供一个简单的shell接口，不会彻底down掉).
所以，并不是如gao版所说：“主硬盘和第二硬盘作为一个整体被GRUB接管”，而是grub的stage_1.5没法找到hdc上的stage_2(/boot/grub/)，自然连windows都进不去了。
这就是一些grub的简单内幕。如果了解一点的话，就不会在安装时发昏了。
[ 本帖最后由 thinkpad_x40 于 2007-2-5 14:30 编辑 ] 楼上解释的相当精彩。。。收藏了。 13楼高手，继续学习了 很奇怪，我的menu.lst只要修改Kernel那一行就可以了。参见我原来的问题:
http://www.linuxsir.org/bbs/showthread.php?t=293920
当然我装的是纯ubuntu，没其他的系统。 这些技巧比较高深,慢慢学习一下 我的T40也碰到这样的问题啊~!~~回家研究一下啊~ T4也可以么？
