USB works, not DVD

meetdilip · February 12, 2020, 4:02am

Tried on another machine I have access to. It has a strange BIOS. It lists oddly. No mention about using DVD as first boot priority. I tried with an Aomei rescue disc and 18.04 DVD. None of them were detected / mention when I tried to choose the boot priority.

OK, thanks.
See what happens, if you try to boot from optical drive, but it is empty.
Does this trigger the LAN boot, or just boots from the HDD after it fails?
What happens, if you put a data disc (not a music CD nor DVD video) in the optical drive, and try to boot from that? Apparently this will fail, but want to see, if your BIOS boots from the next item (HDD) ins this case, or jumps to LAN boot attempt?
What happens, if you try to boot that Aomie disc? Is that bootable on that computer?

Edit:
Just another hint:
https://help.ubuntu.com/community/BootFromCD

" CD/DVD drive can’t boot in AHCI/Raid mode
A large number of CD/DVD drives have problems running under AHCI/Raid mode (from not working at all to refusing to boot)."

Can you try to move away from AHCI temporarily?

I doubt whether my DVD drive is physically disabled. Is there any command to check that ?

I will follow you instructions and update you.

As per today, there is no indication on Ubuntu that a DVD or a DVD drive is present when I put

Ubuntu DVD
An old Windows 10 insider DVD
Aomei Rescue DVD ( based on WinPE, I guess )

There is no detection inside Nautilus now. Not sure why.

meetdilip · February 12, 2020, 10:29am

How to ? I didn’t follow a word, sorry.

kovacslt · February 12, 2020, 10:30am

I would write
ls /dev/sr*

If that reports no such file or similar, the optical drive vanished.
If you see sr0 for example, it’s there…

meetdilip · February 12, 2020, 10:32am

Looks like it is there.

$ ls /dev/sr*
/dev/sr0

kovacslt · February 12, 2020, 10:33am

That was just a shot in the dark. SATA ports usually have different modes. The default is AHCI, but can be RAID, or legacy. In BIOS this setting should be there, but so many BIOSes exists, I can’t say a certaine place/menu.

meetdilip · February 12, 2020, 10:35am

No, nothing like that. I sweeped BIOS last day. I will check again.

kovacslt · February 12, 2020, 10:35am

It

Glad… it’s present at least. If you put the disc into it, does it spin up? Does it recognize the disc, or ANY other disc?

meetdilip · February 12, 2020, 10:37am

Luckily, yes. I had an old recovery disk. I got a popup for new disc inserted and Nautilus shows it too.

kovacslt · February 12, 2020, 10:43am

So that it’s there and working. If you get no similar popup for the other discs, I’m afraid those discs are defect. At least THIS drive cannot read them properly. Maybe your drive tends to its end of life, and reads some discs, and does not read others.
Is this drive old? (more than 2 years?)

meetdilip · February 12, 2020, 10:47am

This time I got the same popup for the not booting Ubuntu disk. It can be mounted through Nautilus as well

ubuntu popup

This is strange. I am more or less sure that if I try to boot from this DVD now it won’t but will work if I use a bootable USB

This is what I get from Nautilus for the bootable 18.04 DVD

meetdilip · February 12, 2020, 10:56am

Just tried to boot from DVD. The same error message.

Yes, the machine is a bit old.

PS: The DVD drive just put in a notification as I shared in the above posts. That Ubuntu DVD is there.

Something is preventing from CD booting. I am not sure what. I burned it right as far as I recall. Thanks.

kovacslt · February 12, 2020, 11:53am

Do you have an older -say Ubuntu 14.x- boot CD? Would that boot?

meetdilip · February 12, 2020, 1:41pm

Tried 14.04 DVD - no luck

Got into BIOS and set it to default.

Tried with 16.04 DVD - again no luck

checking logs after inserting a disc might be helpful to determine if there are problems. i believe ubuntu has a log viewer, but you could also use something like cat /var/log/syslog | tail to see the last 10 messages. if you think more messages might help, you can add -n 15 (or higher number) to get them.

No, I just logged in. There is one tab with Google search from previous session. But it was not activated.
