Specs here, in case anyone is interested:
I had a 2nd 2TB WesternDigital HDD installed, and a multi-card reader. And knowing I would install my custom MimeticDE-Lubuntu OS on it, I asked him to leave off PCLOS and ship it bare metal. I think I'm fully prepared to process whatever gets thrown at it. But I did have some issues with installation, which was a major surprise after KNOWING the box was linux-friendly.
Long story short, this was my first installation on a UEFI motherboard and I didn't know what I didn't know. In hindsight, I would've let GorillaBox install PCLOS and just overwrote it (or perhaps dual-booted) with my own OS. I think I'm good to go now, but there was an error in the boot-repair log that I want to ensure was addressed as part of my repair. I sent an e-mail to the firstname.lastname@example.org address specified, but while I'm waiting for a response, figured I ask our resident experts their thoughts. Copy of e-mail sent was as follows:
After much googling, and trial & error, learned the hard way to create an EFI partition for the Ubuntu installer (Ubiquity) to install GRUB boot loader. Utilized Yanni Boot Repair to fix broken boot and was finally able to boot...only to be followed up with a black screen issue, which "nomodeset" allowed me to workaround, only to discover that the installed kernel in my live distro (4.4.0-034) needed to be updated. Fortunately, updating the system kernel to 4.4.0-104 fixed the graphics issues related to booting and provided correct scaling.
I'm now booting Lubuntu 16.04 successfully, with no issues. So I think I'm good to go, but saw a warning on line 1887 of pastebin report:
Locked-ESP detected. You may want to retry after creating a /boot/efi partition (FAT32, 100MB~250MB, start of the disk, boot flag). This can be performed via tools such as gParted. Then select this partition via the [Separate /boot/efi partition:] option of [Boot Repair].
I believe I have done this already, which enabled me to boot. Is this a false or harmless warning? Is there another issue in my boot sequence that is waiting for an opportune moment to rear itself? What can I do to remedy this error before it becomes an issue? Full report linked below:
Please advise, and thank you in advance!
What do you folks think? Am I good to go now? (the machine is booting as expected, without issue) Or is this "Locked-ESP" error waiting to bite me in the butt later on? Can anyone explain this error to me?
In the "Install Ubuntu" process (Ubiquity), I chose the "something else" option and created a 200MB "EFI partition" formatted with FAT32 and put a boot flag on it; created a 120GB partition for root, formatted with EXT4; and created a 4GB swap partition on sda. On sdb, I utilized the entire 2TB drive as a home partition, also formatted EXT4. Everything installed successfully, as expected, but the newly installed OS wouldn't boot.
Fired up the live disk, used gparted to verify partitions (as outlined above) and saw nothing wrong. So I installed Yanni Boot-Repair from PPA and ran "Recommended Repair", which generated log file referenced above. But after the recommended repair, everything was fine. I'm just looking to understand what happened...what is a "Locked-ESP"...how did that happen...am I truly fixed, or did I just stumble onto a workaround? Educate me please!
