I did the same things. I didn't find such a thing. Boot from internal disk is OK. The only different thing is format. I use below,
diskutil eraseDisk JHFS+ "MacintoshHD" /dev/disk0
and then I use Diskutil App(not command line tool, High-sierra containing).
I'm not sure that I remember that Diskutil App(not command line tool, High-sierra containing) has not "APFS" menu to formt Disk at first format(non APFS). for APFS formatted disk APFS menu appears. Diskutil App(not command line tool, High-sierra containing) dose not recognize non-fromat disk. So you might use command line tool, as like me. I chose JHFS+, I think that High-Sierra installer will change the format from JHFS+ to APFS.
You can re-format using Diskutil App(not command line tool) after formatting using command line tool(diskutil). first format by command line tool(diskutil) should be JHFS+, avoiding some troubles.
I'm not sure that this different is the reason of boot trouble. But I don't surprise that some sequential routine (like EFI Boot-rom change) may happen at initial install of High-Sierra.
It would be great if you could refer to something.
Hello @t0mX,
Thanks for the answer. I tried it!
First I have formated my Kingston KC1000 with 4k sectors using xubuntu USB Key.
Command: sudo nvme format -l 1 /dev/nvme0n1
Worked, and I can see correct 4k format sectors with nvme utility.
Then reboot to High Sierra USB disk and opened terminal. Now disk is blank and cannot view it from the Graphical disc utility, so I have to use command based diskutil:
Command: diskutil eraseDisk JHFS+ "Macintosh HD" GPT Disk0
GPT Partition table created and JHPFS+ partition created. Now disk can be found to install High Sierra. As part of the install process, partition is converted to APFS. Installed High Sierra again and at some reboot have seen blinking ? folder.
Pressed "alt" and forced to boot to "Macintosh HD".
Reset again PRAM & SMC after each reboot.
With High Sierra fully installed I have openend boot disk utility from setting and have configured to boot from "Macintosh HD". (reiterated)
Now directly boots to Internal Kingston SSD HD, after 30 seconds delay, and OSX boots correctly without having to press "alt" each time.
But if I press "alt" still shows orange disk!
But if the disk boots directly to OSX, the only aesthetic inconvenients are 30s delay and "Orange" color of hard disk, nothing serious!
Best regards,
Joan
