I suggest to install windows first and then install centos. You can use the installation disk to partition the disk first, so that the structure of the entire disk will be simple and clear. You must leave at least 2G of the main partition for CentOS, otherwise the /boot space during installation will not be enough (detailed explanation: https://blog.csdn.net/dimolin/article/details/51503284). My approach is to leave 100G windowsC disk, 2G main disk, 100G free disk to CentOS, and the rest to windowsD disk.
You can refer to the following for making a U disk boot disk:

Activate available KMS or buy genuine system.
The installation process was originally evolved from xiaoyao-lxy's "Detailed explanation of installing CentOS 7 dual systems under Win10". The original link is as follows:
https://www.linuxidc.com/Linux/2016-06/132051.htm
However, there are hidden traps in the article. For example, the difference between the old BIOS boot and UEFI is not explained. The above article uses the BIOS boot by default, so if the computer is booted with UEFI at the beginning, it will prompt the UEFI installation needs /boot/ in the middle. Special file support for efi.
The method to solve the UEFI error report comes from Shun's "For a UEFI installation, you must include an EFI System Partition on a GPT-formatted disk, mounted at /boot/efi", it is recommended to set the UEFI of the motherboard to legacy or the USB flash drive The EFI folder in the installation file is completely deleted, and the test is feasible.

Among them, there is a step of U disk setup guide in xiaoyao-lxy's "Detailed explanation of installing CentOS 7 dual system under Win10" without explaining the specific operation method, but in the invisible "centos7 U disk installation stuck at starting dracut initqueue hook" explained Very detailed, the original link is as follows:

However, there is a parameter in the article "centos7 U disk installation stuck in starting dracut initqueue hook" which is intangible and tangible, which will cause the resolution to be abnormal during the installation process and the installation cannot proceed normally. The nomodeset parameter needs to be removed.
The role of the nomodeset parameter is described below:

After CentOS is installed, if you cannot enter windows to boot, you can refer to Xiaoqiaoxq's "Unable to boot win7 after installing centos on dual systems", the original text is as follows:

After CentOS is booted, it is necessary to set the automatic mounting of the hard disk to be perfect. You can refer to bckong's "Mount NTFS file system under CentOS 7 and implement automatic booting" The original link is as follows:
