Grub options move slow

Hi everyone.
I have a little issue here, I could even live with it, perhaps it is the way it is, but I wonder if I could fix it.

I dual boot windows 10 and Opensuse Tumbleweed. I actually upgraded from Opensuse 15.
Windows in sda.
Opensuse in sdb.

Since my old Opensuse install grub takes almost one second to change between options, when I hit enter I need to do it several times (arround 5 times) until it chooses the option.
Sometimes the grub freezes and it will not enter, I need to reset the pc and do it again.

I suspect the boot loader should be sda because it is the first disk and it is in sdb instead.
I am not sure how to verify that.

Thanks.

In Yast Boot Loader:

Click on the “Kernel Parameters” tab. Then uncheck the box “Use graphical console”. Then click “OK” to complete.

You will get an uglier grub menu. But it might be faster because it doesn’t depend on using any graphics.

It is at least worth trying. If you don’t like the changes, you can undo them just as easily.

Indeed it worked.

Thanks
