Install an operating system

When you purchase or reinstall a GPU Elastic Physical Compute (GEPC) instance, you must specify the operating system to be installed.

Operating systems provided in the EPC console have been tested and certified by the server vendor and Kingsoft Cloud to ensure that EPC instances can run correctly in data centers.

Install the operating system when you purchase an instance

1. Log in to the EPC console. The EPC instance page appears.

2. Click +EPC to enter the page for creating an EPC instance.

3. In the Select Image step, select the desired image. For more information about how to create an EPC instance, see Create an EPC instance.

   For a GEPC instance, the standard image list provides images that have installed CUDA. You can choose an image from the list.

Reinstall the operating system

The system reinstallation operation is not supported on non-standard leased server types. For standard leased server types, the system can be reinstalled online.

1. Log in to the EPC console. The EPC instance page appears.

2. Find the target EPC instance, and then choose More > Reinstall System in the corresponding Operation column.

3. Select the desired image, bonding type, and RAID type, and then click Next.

4. Select the SSH key, set the administrator password, and then click OK.
