Lose GRUB option after deleting NVIDIA driver

I deleted my NVIDIA driver following this instruction. Then I followed this instruction to install the NVIDIA driver. I did not create a snapshot (big mistake) and did the 2 commands:

# zypper in -t pattern devel_C_C++ devel_kernel
# zypper rm drm-kmp-default

Now I can’t boot because there’s no openSUSE option in GRUB, what do I do to fix this?

Hi, welcome

You also don’t see it in the advanced options?

Thanks for the response. Luckily the system automatically take snapshot so I rolled back to the last one and successfully installed the driver.
