After the first cheers some follow up: Grub seems to remember last booted entry, that's probably why this now works. After logging in with ssh and looking thru the /var/log/*/log files some errors showed up: Some related to postgresql, some to synoindex. Fixed with the help of this forum! Updated to Update 8. All seems OK!

Nope. Didn't change anything there...

Being a leecher, just registered to say thanks too! N36L (AMD) with two 0.5TB HDD up to 6.0.2 update 7, all packages now updated too. Changed the PID, VID, SN en MAC as well as the AMD default="3" in grub.cfg on the USB after the dd to /dev/sdc. It didn't seem to function, as it still defaulted to 0, as where the AMD is 3 imho? Hooked up a keyboard and a monitor, manually selected the AMD boot option, booted, installed, miraculously, after the first reboot grub was updated on the USB? Anyway, got a working 6.0.2 update 7 now!
