No Partition Detected...oh there it is!

Post by Linko » Thu Mar 08, 2018 5:47 am

Hi,

When booting up my linux machine I'm getting (and have just started getting) a black screen stating that there is no active partition found. Then the bottom 50% of the screen displays, what looks like, TV static - random pixels. Then the machine boots and all is fine, all in about 3 seconds. Strange me thinks!

Although I can live with this for the moment it clearly isn't right and could obviously result in bigger issues.

My question is, has anyone else experienced this or have any clue what may be causing this weirdness?

I'm using 'Sarah' on a Intel i3 with 16GB RAM and on-board graphics (and sound and LAN etc).

Thanks.

Did you verify the ISO file before doing the install.?

How did you do the install, DVD or USB.?

I installed via usb thumb drive but that was a while ago and it has been fine for well over a year. I've updated and upgraded in the usual way. Thinking about it though, I did change which kernel I was using not long ago, but it didn't react like this immediately so I guess I need to try another and rule that possibility out.

The ISO came from this official Linux Mint site (before the 'complications') but no I don't think I did verify the download :oops:

Fyi, the proprietary Nvidia and AMD graphics drivers may have conflicts with the Linux kernel patches for Meltdown and Spectre = need to use the open-source nouveau and fglrx drivers.

Certain Level 4 and Level 5 updates can bork the LM system = should have a backup ready, eg revert to an older stable Linux kernel.

TBH I don't really know much about the kernels for Mint (or in general truth be told). Do you have a suggestion as to which one I should use primarily? Which is currently the most stable in your opinion?

I guess I should have another one to hand in the boot menu as well just in case, like you say, it fails.

As a general rule the newer hardware you got the better supported it is in a higher version of a kernel. You could try 4.4.0-116 or 4.13.0-36 . Both come with the latest security patches.
Open Update Manager --> View --> Linux kernel.
Installing a new kernel won't remove an earlier one, so you would still have your current one to boot up with in case the new one doesn't work.

By the way, it would be good if you could provide the spec of you system. Run

Code: Select all

inxi -Fxz
in a terminal and copy-paste the output between code tags: </>.
I suppose that's one of the ironies of life, doing the wrong thing at the right moment -C.C.

Thanks, I'll run the command when I get home - at work at the minute.

Cheers for the guidance guys, I'll let you know if it makes a difference using a different kernel.

Ok so the message 'no active partition' is what actually shows BEFORE the boot menu even displays.

Not sure what this is but would it suggest it's nothing to do with the kernel as I haven't selected one yet?

I think the momentary "No active partition" message is because you have 3 internal hard-drives and your Boot order was not set properly in UEFI-BIOS setup, ie your computer was looking for the proper boot drive/device. Your 1st Boot device should be set to the hard-drive where you have installed LM.

Thank you for taking the time to read through that lot...

I'm either going to be incredibly thick here, or answer my own question, but is it because I unplugged all the hard drives when trying to change the power supply unit (that didn't fit the stupid case I have so I put everything back as it was - or so I thought) and I've plugged them back in in the wrong order?

Could be.

AFAIK, when you installed LM, the LM Installer will register the Grub.efi bootloader file in the NVRAM(= a Flash memory chip) of the UEFI-BIOS firmware, besides installing the Grub.efi bootloader on the hard-drive. Whenever you boot LM, the UEFI-BIOS firmware will check for the presence of the Grub.efi file in NVRAM before allowing the OS to be booted from the internal hard-drive.

(One possible workaround to this problem is to copy GRUB from EFI/ubuntu/grubx64.efi to EFI/BOOT/bootx64.efi = create a new folder, BOOT, in the EFI folder and rename grubx64.efi to bootx64.efi. Restart.)

FYI here is a good article on UEFI https://www.marksei.com/bios-uefi-explained/

So, reading that and what you have said - I think I have plugged them back in wrong. The UEFI partition to boot the system cannot be found on the first hard drive it encounters, and therefore looks to the other hdd's and then finds UEFI and boots from there.

I could be talking complete rubbish, but this is what I'm understanding from all this.

This is understandable, but what's puzzling me here is the "TV" like static at the bottom of the screen. Unfortunately I don't have an answer for that one.

The only tie I have ever encountered this was back in the Goodle Days when computers were slow as molasses (and we thought they were fast) when the machine first booted up and the video BIOS loaded initially. But that happens...usually...before the system BIOS goes off looking for hard drives.

Interesting. Do let us (well, me...) know if this behaviour stops when you get the disks sorted out.
I have travelled 35629424162.9 miles in my lifetime

One thing I would suggest, create a partition a ~28G partition as /. Partition the rest as /Home.
When the system fails, reinstall and use the exact same username and all your 'stuff' comes back to you.
