How to take out the important files in the bad c drive

Introduction: Two mail servers, simultaneous use, data synchronization, even backup and redundancy, now called A, I want to install the system is B, B has two disks, one disk is a partition, They are C and D respectively. They used to use the C drive. Now the C drive system is broken and can't get in, but all the data is in the C drive.

I am going to install the 03 system in the D drive. The previous D drive also has a system. I want to use the repair to see it, but it is useless. It indicates that there is a problem with the drive C. It cannot be repaired and cannot be installed. Press F3 to exit, press F3, prompt 15 seconds to restart the calculation, after restarting, I try the new installation again, but after formatting, it prompts the C drive to have a problem, and the same prompt, I restarted, several times, met The same is the same prompt, press F3 to restart, in desperation, go back, I can't understand why, why do I have a problem with the C drive when I install it on the D drive?

Answer: The C drive of the server is really broken, so every time you check it, you can't go through it, so it will lead to that situation. Let's start with the simplest method, which is also the method used by Yu. Modify the parameters in the BIOS, change the drive letter of the C drive and the D drive, and change the C drive that has been broken to the D drive. When the system checks, it is based on the drive letter, so you can change it after this change. Check the good disk first, so that you can enter normally, you can do a normal new installation!
