After reinstalling the win7 system, I found that the hard disk cannot be partitioned. How to solve

1. First make the u disk as the boot disk, then boot it to the u disk to boot

2. Then restart the computer and enter the PE system. The ISO image of WINDOWS7 is decompressed to a non-c disk;

3. After entering the PE, format the C disk to NTFS, (the C disk size is set to 30G or more);

4, the key part from D: win7 copy boot, bootmgr and sources these three files to the root directory of the C drive, as shown below;

5, run cmd in PE, enter "c:boot?ootsect.exe /nt60 c: & rdquo; (note that there is a space between exe and /and nt60 and c:) After entering the car, you will see the prompt that the word "successful" is successful, then restart the computer;

6, after pulling the U disk Out, the computer starts to install win7, follow the steps, no longer will not be able to partition.

7, after installing the system, there will be two boot options, there is a windows setting to start, then how do we delete it, open the command prompt as administrator to run cmd, enter "ldconfig; msconfig", open the system In the configuration dialog box, select the "Boot" tab, select the boot project you want to delete, click Delete, and be careful.
