I found the AHCI. It is enabled (“Configure SATA as AHCI”). The other option id IDE.
looks ok… maybe it doesnt have secure boot…
maybe its how you installed manjaro?
post output from:
lsblk -o PATH,PTTYPE,PARTTYPE,FSTYPE,PARTTYPENAME
This is with the usb plugged in. Hence the sdb and dos PPTYPEs.

And I think I sent this earlier, but parted -l gives:

Disk /dev/sda: 500GB

2 158GB 168GB 10.5GB linux-swap(v1) swap
3 168GB 500GB 332GB ext4
I think I saw one post in the forum that suggested removing the swap flag on the swap partition. I have not tried it yet. Should I?
And I used the graphical installer, and note that the partitions are not quite in the order I created them during the install. I had the fat32 partition 1st, but I see it’s still physically at the start of the disk. I’m not sure that matters… At one point (maybe it was the MBR days) I think it did.
everything looks ok…
i dont know about this, but you can try:
i think its a bios thing… disable the legacy boot and if you find CMS, disable that too
Disabled legacy boot (UEFI only), and I don’t see CMS anywhere.
Same problem: “No OS found”.
i have no idea whats the problem could be… either its a bios thing, or how it was installed…
you can try to remove both entries from the efi directory:
sudo rm -r /boot/efi/EFI/Manjaro
sudo rm -r /boot/efi/EFI/boot
then reinstall it again:
sudo grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=manjaro --recheck
sudo mkinitcpio -P && sudo update-grub
I’ll give that a try.
I searched and found this, which seems to suggest I may need to update the bios. What do you think?
I don’t know how to do that. I’ll try your suggestion first.
Thank you for your help.
Just to followup:
I did try removing the /boot/efi/EFI subdirectory and re-installing grub. I had no errors with installing grub, so updated. However, this did not solve my problem with booting to Manjaro.
Some more searching leads me to think that it is a problem with the bios I have on this machine. In addition to the link in my above post, I have found some more things I may try:
https://superuser.com/questions/1692006/lenovo-m93p-will-no-longer-boot-from-hard-drive-or-usb-drives (one post discussed M92p)
As to how to update without a windows OS installed, these may be useful:
nice find, it really looks like there is a problem with uefi on this machine… so just disable uefi and enable legacy, create MBR and install manjaro in legacy/mbr mode, which according the links should work …
Yep. Confirming it did work.
I did consider updating the bios, but could not see that the reward was worth the risk, since I did not have windows installed, and that seemed to be required for the default method.
Thank you again for your help in resolving this issue.
