Nodegrid OSes version 5.0 or below are Legacy Only, which means those images are not capable of booting in a system configured for UEFI Boot Mode. In a system running one of those images can be upgraded to new versions but will still run in Legacy. To Upgrade a Legacy device with a new image in UEFI mode, the following procedure is required:
- On a USB drive, copy the NG 5.X UEFI image
Or setup a PxE Server with NG5.X UEFI Netboot Tarball. - During installation, select Install Nodegrid formatting disk.
- After installation, refer to Intrusion Prevention.
- Reboot the system.
Enable Secure Boot (optional)
- Go to Security :: Services :: Intrusion Prevention.
- Select Enable Secure Boot checkbox.
- Click Save.
- Reboot the device.
Nodegrid OS version 5.1 and above are both Legacy and UEFI compatible.
