the embodiment provides a dual-system coexistence method, which enables a user to switch between a Linux operating system and a Windows operating system quickly, efficiently and safely.
The system applying the method at least comprises a client and a server; the client is a thin client or a Personal Computer (PC), has local computing capacity, and uses a Linux operating system to run and use the functions of the Linux operating system and establish a virtualization environment under the Linux operating system to use a Windows operating system; the server is a cloud server deployed at a service provider; the client is connected with the server network to form a basic cloud computing system.
Referring to fig. 1, the dual-system coexistence method in this embodiment is directed to the operation of the client, and includes the following steps:
s1a, the client accesses the Windows image file in the server under the Linux operating system.

Therefore, the safety performance of the system can be effectively improved.
Further, in step s1.3b, when the client accesses the network block device, the server verifies the access authority of the client to the network block device; if the client has the access right to the network block device, the server allows the client to access the network block device; and if the client does not have the access right to the network block device, the server refuses the client to access the network block device.
