ubuntu18.04にNVIDIAドライバーを入れたが-smi表示せず

Question

Windows10PCの外部SSDにubuntu18.04を入れ、NVIDIAドライバーを入れてリブートさせようとしたら下記の表示が出た。そのままリブートすると
nvidia-smiのコマンドに対してステータス表示せず。ドライバー等が認識されていません。

Your system has UEFI Secure Boot enabled.
UEFI Secure Boot requires additional configuration to work with third-party drivers.
The system will assist you in configuring UEFI Secure Boot. To permit the use of
third-party drivers, a new Machine-Owner Key (MOK) has been generated.
This key now needs to be enrolled in your system's firmware.
To ensure that this change is being made by you as an authorized user,and not by an
attacker,you must choose a password now and then confirm the change after reboot
using the same password, in both the "Enroll MOK" and "Change Secure Boot state"
menus that will be presented to you when this system reboots.

リブート後にパスワート等を聞いてくる事はないのですが・・・
ご指導よろしくお願いします。

BIOSでセキュアブートを無効にしてみてはいかがでしょうか。
