2 SSDs each with EFI boot - 4 OS installs - why internal doesn't boot first?
Older dell laptop using UEFI not legacy. Internal SSD and a removeable repurposed SSD connected with a USB3 adapter. UEFI boot order in bios setup shows Ubuntu, Windows, KDE Neon, Manjaro order. I could take a picture with phone if needed.
When external SSD is connected it boots to manjaro grub where I have ubuntu as default (I try). If extern not connected it does boot normally to ubuntu grub and I can choose windows or neon from that grub menu. But nothing I do short of using F12 for one-time boot will boot EFI on internal sda1 when external is connected: With external connected from within ubuntu on sda3: Code:
$ Fdisk -l sda3 - kubuntu daily driver with data backed up regularly sda4 - KDE Neon am trying it out daily pretty happy so far sda5 - shared storage for linux and windows Other info from within ubuntu: Code:
$ dir /etc/grub.d Code:
$ sudo update-grub Code:
sudo efibootmgr |
Check device boot order in bios settings with external drive plugged in. After testing the installation of linux mint, regardless of what I did the installation would grab the internal esp partition. I didn’t try changing device boot order in bios settings. The only work around I was able to figure out is to unmount the internal esp partition and mount the external esp before the installer gets to the grub installation stage. This also requires after installation the editing of /etc/fstab to mount the correct esp partition during boot up.

Boot order in BIOS setup screen is the same whether I have the drive plugged in or not. ubuntu, windows, neon, manjaro and UEFI firmware on the lexar (sda1). I don't see an option for the ocz (sba1)efiboot but is bootable obviously as it goes to manjaro's grub menu and I can choose any of the others there.
If I do get to installing mint again it wouldn't be until the buntus get their multiboot family act together. You can't have your customers trying out or just wanting a second flavour of a buntu on same machine but they are not able to because of that naming in EFI issue. People will just have to try out other offerings. I know so many that have multiple installs of debians, SUSEs, etc. I used to even have more than one flavour of PCLOS on one machine. This new issue, I don't know what is making it boot a partition it is not recognizing to chose but rather by the manjaro /root in grub. Could be something peculiar to my firmware or a quirk of manjaro like that btrfs snapshot boot file I didn't ask for. I will pursue that in a manjaro forum. |
You don’t have a usb drive/key option in settings that can be moved after disk drive. This is in bios settings, not bios boot menu

What you report makes me suspect that you have not gotten down to the device priority level of the motherboard BIOS settings. |

I will get a pic of the screen in boot tab of setup and what options are in there. |

Trying to get to the heart of the matter why it is booting a removable rather than the internal? With the external unplugged it boots just fine to ubuntu's grub menu. Only when the external is plugged in does it jump to manjaro's on sdb1 bypassing sda1. Maybe it is a feature where they assumed that if you plug in a bootable external you did it to boot it? The laptop is close to ten years old. |
whats under advance boot options and/or system configuration?

Configuration is various and includes USB config to enable both USB support and supporting booting external. Including a pic of the add option in UEFI boot order to add. Those strings in the middle are pre-populated and I really don't know where to fetch the rest or if it relevant to current behavior. |

Next steps? I am enjoying trying out manjaro but we aren't going steady or anything not to mention I have to see about removing snapshot and whatever btrfs it got going there, as a matter of fact it was why I fdisked afterward to look for btrfs (I know nothing about snapshot, does it work on some virtual btrfs drive or something?) I can blow away everything but the one storage partition on there (sdb3) that has my backups from internal drive. |
also the output of:

That's odd all of the efibootmgr entries are from sdb1 except for this one:
