Cover image via SAYSCcboot Image Link -
If clients fail to boot with errors like “Image not found” or “Boot from NIC – No boot filename received”:
Add image to CCBoot server
Create client entries (image linking)
Configure network boot (if not already)
Boot and verify
Manage and update images
In a diskless boot environment—common in网吧 (internet cafes), schools, and corporate labs—every client computer runs its operating system from a centralized server. CCBoot is a popular solution that enables this, and at the heart of its efficiency lies the concept of the image link.
In CcBoot, go to image properties. Set "Client RAM Cache" to 2048MB or higher. This tells the client to load the critical boot sectors of the image link into local RAM, reducing network round trips.
Right-click your image link > Properties > Disk Type. Change from "IDE" to "VirtIO" . This reduces CPU overhead during network transmission, though you must install VirtIO drivers on your super client first. ccboot image link
CcBoot does not have a GUI backup, but you can use a batch script:
@echo off
net stop ccbootservice
xcopy D:\CCBOOT\Image\*.img E:\CCBOOT_Backup\ /E /Y
xcopy D:\CCBOOT\Config\*.mdb E:\CCBOOT_Backup\Config\ /Y
net start ccbootservice
echo Image link registry backed up at %date% >> backup.log
What to restore: If you lose the image link, restore the .img files AND the clients.mdb (Microsoft Access database) file. The database stores the MAC-to-Image links.
Q: Can a CcBoot image link work across different subnets?
A: Yes, but you must configure DHCP Option 66 (Boot Server Hostname) and Option 67 (Bootfile Name, typically pxeboot.n12) to point to your CcBoot server's IP. The image link itself is server-relative.
Q: Why does my client show "Cannot link to image" after a server update?
A: CcBoot stores image links using absolute paths (e.g., D:\Images\win10.img). If you changed your server's drive letters, the link breaks. Go to Image Management > Repair Path. If clients fail to boot with errors like
Q: How many clients can share one CcBoot image link? A: Theoretically, unlimited. Realistically, limited by your server's IOPS and network bandwidth. With 10GbE and NVMe, you can link 200+ clients to one image.
Q: Does renaming the image file break the link? A: Absolutely. The CcBoot database references the file by name. Always rename images inside the console, not in Windows Explorer.
A bad link causes latency. Here is how to optimize:
