I have lost my boot menu

Hi There,

I need your help. I have reinstalled my NetBSD 10_RC1 on a partition of 
my GPT partitioned disk. However for some reason, the installation was 
unsuccessful when writing the OS sets to the disk. I assume the 
installer wanted to write the USB stick accidentally. The phenomena was 
that the copy operation was getting more and more time, then stalled. 
So, I abandoned the installation and went to the console. There I have 
installed manually. Unfortunately I could not install the boot chain. 
This means, I have to use my linux's grub2 to start NetBSD now. You can 
see my disk layout here:

-bash-5.2# gpt show ld0
       start        size  index  contents
           0           1         PMBR
           1           1         Pri GPT header
           2          32         Pri GPT table

    33818624   134217728      3  GPT part - Linux data

  1953525167           1         Sec GPT header
-bash-5.2#

The EFI partition for NetBSD is like this:

-bash-5.2# ls -l /boot/efi/EFI/boo-bash-5.2# ls -l 
/boot/efi/EFI/boot/bootx64.efi
-r-xr-xr-x  1 root  wheel  235690 Nov 15 13:56 
/boot/efi/EFI/boot/bootx64.efit/bootx64.efi

I have copied the boot.cfg into the root of the / partition (dk3)

If I want to boot the EFI directly, then it runs the boot program, 
however it does not show the menu at all. I can boot only like this:

> boot NAME=NetBSD:netbsd

Or, as I mentioned, with GRUB2 directly with the kernel.

So, I want to have the menu back as normally. I hope my description 
makes sense for you.

Thank you,

FeZ
