先说ntldr is missing的解决办法，这个网络上很多了，用“ntldr 丢失”做关键词在google里一搜一大把，
2、此时最简单大概就是从别的机器copy一个了，这个时候可要注意，copy后，要无论你采用那种方式，都要注意ntldr没有压缩属性。查看方法如下：
a、在windows界面下，右键，文件属性，高级，里面有个“压缩内容以便节省磁盘空间”，前面的勾不要勾上。
b、在控制台输入dir，就看见了，有r,s等字符，如果里面有c，表示已经被压缩了，需要用ntldr is compressed问题的解决办法。在命令行界面下，输入attrib 文件名,就能看见这个文件的一些属性了。如果有c，用ntldr is compressed问题的解决办法。
ntldr is compressed的解决办法：
1、如果是把硬盘插到别的机器上copy NTLDR文件，copy完成后，请操作如下步骤：
文件上点右键，文件属性，高级，里面有个“压缩内容以便节省磁盘空间”，前面的勾不要勾上。
2、如果是windows修复控制台或命令行界面。在C盘根目录下，输入：
attrib -c ntldr 去掉ntldr文件的压缩属性
下面是这个问题解决的英文步骤，感兴趣可以看下，摘自国外某论坛。
An NTLDR is compressed error is pretty easy to fix(much better then NTLDR is missing errors!).
First you need to boot to the recovery console.
To boot to the recovery console follow these steps:
1. Insert the Windows XP CD-ROM into the CD-ROM drive, and then restart the computer. Click(or press any key) to select any options that are required to start the computer from the CD-ROM drive if you are prompted.
2. When the “Welcome to Setup” screen appears, press R to start the Recovery Console.
3. When prompted type “1″ or if you have a dual-boot or multiple-boot computer, select the installation that you must access from the Recovery Console.
4. When you are prompted, type the Administrator password. If the administrator password is blank, just press ENTER.
5. Now you should be at the comman prompt and ready to repair the ntldr file!
Now all you need to do is enter the following commands(in order) and each command on a new line just like you see them here:
Code:
cd \
attrib ntldr -c
exit
