So hd2 is the Mac drive then?
What does set say about the root & prefix?
If you have a live ISO image handy can you post the output of
efibootmgr -v parted --list

Fix/Ignore?I see no error flags why kernel fails to boot, do you?
Would you suggest I reinstall GRUB onto sda or try installing GRUB onto beowulf root, sdb?

You could start the medium, use the rescue mode, chroot into the installed system and try your luck with the commands.

rolfie,
I've had very little experience using chroot, especially with devuan. Could you please walk me through a quick chroot session, beginning with the ISO rescue mode to entering CLI commands? In fact the devuan ascii 2.0 HDD came in mighty handy to rescue issues related to the old mac, which no longer boots after the beowulf upgrade.

efibootmgr -v parted --list
Hi,
Yes, and booting via macOS uefi requires the GUID partition map, which might be corrupted.
Why not have the option to add bootloader to the USB external HDD?
The only ISO at my disposal is:
devuan_beowulf_3.11_RC_amd64_netinstall.iso
How would you go about having it output the data you requested using:
efibootmgr -v
parted --list? . ? . ?

#29 Re: Installation » Non Booting GRUB on Beowulf » 2021-03-25 21:50:13
You need to set the partition as the root rather than the entire device.
Use
ls (hd2,gpt1) ls (hd2,gpt2) ls (hd2,gpt3)Are the kernel & initramfs image (symlinks) listed in the output of any of those commands?
Hi,
No, perhaps that's omitted on beowulf:
grub> ls (hd2,gpt1)
Partition hd2,gpt1: Filesystem type fat - Label ‘EFI’, UUID 67E3-17ED -
Partition start at 20KiB - Total size 204800KiB
grub> ls (hd2,gpt2)

grub>GRUB appears to overlook the beowulf ext4 root/boot partition on the USB external HDD?
It appears GRUB only can find the internal SSD partitions!

set root=(hd0) # might be hd1 or hd2 linux /boot/isolinux/linux initrd /boot/isolinux/initrd.gz bootBut you will be booting and installing in uefi mode. Legacy boot will give you an isolinux boot menu instead of a grub boot menu. Is there a way to force a legacy boot?
Hi,
Agree, beowulf_3.1.1 & devuan_ascii_2.0 was both installed in UEFI mode, but beowulf's GRUB traps this error:
error, unknown filesystem.when quering (hd0), (hd1), (hd2) with:
linux /vmlinuz root=/dev/sda1or
linux /boot/isolinux/linuxI see no way to force a legacy boot, so probably that's what changed since devuan_ascii_2.0 . . .
Q: What's your definition of 'legacy boot'?

#31 Re: Installation » Non Booting GRUB on Beowulf » 2021-03-25 10:30:29
Hi,
Something has changed with GRUB, since Devuan_ascii_2.0_amd64_netinstall.iso was installed on identical hardware:
feature_default_font_path=y
feature_menuentry_id=y
feature_menuentry_options=y
feature_nativedisk_cmd=y
feature_ntldr=y
feature_platform_search_hint=y
feature_timeout_style=y
grub_cpu=x86_64
grub_platform=efi
lang=
local_dir=
net_default_ip=(null)
net_default_mac=(null)
net_default_server=
pager=
prefix=(hd2,gpt1)/boot/grub
grub> ls
(proc) (hd0) (hd1) (hd2) (hd2,gpt3) (hd2,gpt2) (hd2,gpt1)
grub> ls (hd0)
Device hd0: No known filesystem detected - Sector size 512B - Total size 0.5KiBNo sign of vmlinuz & initrd.img, making GRUB think /boot/grub is on efi partition.
Any other clues how to boot kernel?

Hi,
Devuan_ascii_2.0_amd64_netinst.iso installed and was fully functional on referenced hardware.
Referenced beowulf iso install fails to boot kernel, displaying the following:
GNU GRUB version 2.02+dfsg1-20+deb10u4
Minimal BASH-like line editing is supported. For the first word, TAB
lists possible command completions. Anywhere else TAB lists possible
device or file completions.

Please help rescue non booting beowulf GRUB on a USB external HDD.
