Why would an Ubuntu system (16.04 LTS) that boots just fine on one system board refuse to boot on another?
The drive in question has an EFI boot sector, and I suspect this has something to do with the problem, but both boards support UEFI and I've tried it in UEFI and legacy mode.
@woozle What do you mean by refuse to boot? Not getting to grub? getting to grub but not beyond? is it crashing someplace?
I'm having an issue right now with 19.04 that won't get far into the boot because of the graphics drivers, adding nomodeset to the grub entry gets it to the desktop, though it's still not working right.
@mattgen88 It instructs me to insert a boot disk because no bootable media were found (or something along those lines).
If I boot with a livestick, it sees the drive just fine. No filesystem errors. It just refuses to even attempt booting
(ooo, 19.04 is available? been waiting for that...)
@woozle 19.04 is still beta
That said, in your bios, check if you can set SATA Operation to AHCI. That's another thing I had run into on a system. The default is RAID and it couldn't read the storage
@mattgen88 I'll check that.
@woozle "it's Linux" seems a good answer
@woozle Where specifically does it fail to boot?
@dredmorbius On the shelf, up there <points>.
...though probably anywhere, really; I have yet to gather more data points on this.
(If you mean "where" in the sense of "at what point in the process", see my answer to mattgen88 -- short version: it won't recognize the drive as a bootable medium.) (maybe I should turn it down to medium rare?)
@woozle If in UEFI, then the partition isn't marked bootable (unlikely if it boots elsewhere), or UEFI hasn't registered the drive (more likely).
If in GRUB ... misspecification.
If in initramfs, no drivers.
@dredmorbius It's a SATA SSD drive -- does the article still apply?
@woozle Almost certainly.
@woozle Understand the boot process itself, it's complex.
RH, but a good overview:
@dredmorbius I have in fact been looking for an explanation of this. ^.^
I have learned a few things about grub, but this problem happens at some point before that.
@woozle I would start with UEFI.
I've been spared dealing with that to date.
@woozle Hi Woozle! Have you had this question answered yet? I'm just curious.
@cat_tharsis I've been given lots of documentation with which I might be able to figure out the answer, but haven't had time to pursue it... and I unfortunately needed the server back online sooner rather than later, so I moved back to the old one for now :-/
@woozle That's understandable! It's good to see you!
