After a few attempts I managed to install Lubuntu 20.04 on a new Asus VivoBook 513 (Intel graphic) alongside Win10, so that the Grub boot menu appears now (Windows seems to be very obstinate in keeping Hibernate even though I was sure to have done Shot Down. Secure boot is disabled, Hibernate too).
Grub menu appears, thank God. But when I select Standard Ubuntu in the main menu, only the Asus logo (belongs to the EFI BIOS) appears and keeps standing! No booting.
But I can boot via →
Advanced Options for Ubuntu
→ Ubuntu with Linux 5,4,0-70 (recovery mode)
→ Recovery Menu (Wiederherstellungsmenü) → resume : ′startup process normal′
Then the login screen appears quickly and quickly the desktop. And it looks good, screen resolution is correct, audio is working, brightness setting and suspend doesn't.
Also I can boot from main menu → Advanced options for Ubuntu → Ubuntu with Linux 5.4.0-70 (normal) the system.
But it takes very much longer, there are many HUB AE and ACPI Errors (looking for hardware drivers?) (this is actually a second topic, but maybe both can be solved in one? via grub → GRUB_CMDLINE_LINUX_DEFAULT="quiet splash xxxxx??") .
AND UPDATE : After updating the system the boot process stops after all these Errors, last line: hdaudio COD2: unable to bind the codec
there it stops.
Thanks for your time...
