Win7 system can not be installed in the C drive solution

Generally speaking, the user will choose the C drive as the system drive, and the Win7 system is also installed on the C drive by default. But sometimes there will be cases where the system cannot be installed on the C drive. The reason is that the C drive is not the NTFS format. What should I do at this time?

1. Format the C drive first, then select ntfs for the hard disk format;

2. Or open the win7 system command prompt (Microsoft logo key + R input cmd); >

3, enter convert c:/FS:NTFS;

4, you should be prompted that you are using can not be converted, need to restart, let you enter y (yes) or n (no) ;

5, enter y and then restart;

6, then you look at the c drive's property c drive becomes ntfs format, so you can install windows7;

7, or install, choose a new installation, and then select the target partition when there is a button in the lower right of the partition list, the drive option, click to delete the C drive and then create a new C drive can be installed.

The above is the solution that Win7 can't be installed on the C drive. Since the system can't be installed in a non-NTFS format disk, then format the C drive into NTFS format.
