Can't find bootable volume after first reboot

Hey,

all of this is extremely strange. Can you please do the following in order to find out more why it doesn’t continue after it starts booting:

[ol][li]Start the machine.[/li]
[li]As soon as the “grub” boot menu appears (see attached screenshot “grub-main-menu.png” for what that should look like; it’s the smaller one of the two screenshots) hit one of the arrow keys on your keyboard. It doesn’t matter which one; what matters is that grub will stop the automatic boot process when you press any key.[/li]
[li]Next make sure the first entry is still selected and press the “e” key (“e” for “edit entry”). A new screen should appear displaying the details of what grub will do with the entry. It should look similar to the attached “grub-edit-entry.png” (the larger of the two attached pictures).[/li]
[li]Now navigate to the line starting with “linux …”. Please remove the strings “quiet”, “loglevel=0” and “splash” from this line. The result should look similar to the aforementioned “grub-edit-entry.png” where I’ve already removed those strings from the line.[/li]
[li]Next boot this entry by pressing the F10 key. A list of text entries should be displayed, and the boot process should hang somewhere again.[/li]
[li]Finally take a screenshot (e.g. with your phone) of the screen when it won’t change anymore and post that screenshot here.[/li][/ol]

Thanks.

Kind regards,
mosu
