partition not found (Solved via reformat)

[Brotherred]

Hello all. I am new here. I have been a Linux user for about twenty years but still rather n0obish, sadly. Anyway I have been running Peppermint OS for long time (v3) and now I have Pepp6 installed on a old laptop. I have posted this issue to my Distro forums here: http://forum.peppermintos.com/index.php/topic,3204.msg31635.html#msg31635

My full system configuration is here:

$ inxi -a
/usr/bin/inxi: illegal option -- a
Error 7: One of the options you entered in your script parameters: -a
is not supported.The option may require extra arguments to work.

           ID: /usr size: 14G used: 8.3G (63%) fs: ext4

You will see there in my Distro forums that the suggested code that I was given was:

Code Select Expand

menuentry "Install Plop Boot Manager" {
    set root='hd0,msdos7'
    linux16 /boot/plpinstc.com
}

And just today I tried /dev/sda6 and /dev/sda9. All of these have failed. I am not sure of where this issue may be already posted here in this forum. I have searched but did not see it. Any help would be much appreciated. Like I suppose many here LIVE USBs have been a huge help to me.

Hello,

You will see there in my Distro forums that the suggested code that I was given was:

Code Select Expand

menuentry "Install Plop Boot Manager" {
    set root='hd0,msdos7'
    linux16 /boot/plpinstc.com
}

This configuration makes no sense.




I suggest that you use the Live version. Use plpbt.bin instead of plpinstc.com. When your /boot partition is the first partition on the hard disk then use for grub2

Code Select Expand


#!/bin/sh
exec tail -n +3 $0

menuentry "Plop Boot Manager" {
    set root=(hd0,1)
    linux16 /plpbt.bin
}


See https://www.plop.at/en/bootmanager/plpbt.bin.html#rungrub2



Best regards

It seems then that a major issue then is that I have my /boot at the end of the drive. Is there a remedy that does not involve my rearranging my partitions?

Regards

[Elmar]

It doesn't matter if the /boot partition is the first or last partition or somewhere in between.

When your /boot partition is sda5 then change
set root=(hd0,1)
- to -
set root=(hd0,5)

Code Select Expand


#!/bin/sh
exec tail -n +3 $0

menuentry "Plop Boot Manager" {
    set root=(hd0,5)
    linux16 /plpbt.bin
}


See the Grub2 documentation for details.

I did everything just as you said, I believe. And it still says partition not found. Oh and I reinstalled the system and put the /boot at the beginning of the drive. I did that before your reply about that.

You did not everything, you also have to remove the /boot in front of /boot/plpbt.bin in the config file.

I just dunno. Still can't find the partition.

#!/bin/sh

Would compiling the source code help? Not that I look forward to it the compiling process for plop is nothing like I have seen before.

Regards

[Elmar]

Compiling the source would not help anything. The problem comes from your Grub configuration. I don't know if it makes a difference and I have no time to check it, but you did not set a "/" in front of plpbt.bin.
Can you make a photo or a video with a smartphone of your monitor when there is the "partition not found" message?

[Brotherred]

Yes, after I set the /

[Brotherred]

Yeah it failed like you seemed to expect. Here's the picture.

[Brotherred]

Sorry is this picture hard to view? Is there anything that I can do for this situation?

You are using Peppermint Linux. I tested now a standard installation of Peppermint linux and the plop boot manager started flawless from the grub menu. The standard installation doesn't use an extra partition for /boot. So i did a second test with /boot on a logical partition and the plop boot manager also started without any problems from the grub boot menu.

What is the device node of your /boot partition.

[Brotherred]

I apologize that had to have been frustrating. I have preferred it this way since back when I ran Fedora Core 3. I can't imagin why your /boot works and mine does not.

# /boot was on /dev/sda10 during installation

[Elmar]

I... I can't imagin why your /boot works and mine does not...

Because I am setting the correct root= in the grub config.

# /boot was on /dev/sda10 during installation

This just show what was and not what is. The mount command will show to what device node the /boot is mounted too.

However, I assume it is still /dev/sda10. Now the config is

Code Select Expand


#!/bin/sh
exec tail -n +3 $0

menuentry "Plop Boot Manager" {
    set root=(hd0,10)
    linux16 /plpbt.bin
}


the grub root= must be the equivalent of  the device node where /boot is mounted.

Regards

[Brotherred]

I tried that and it failed. Indeed my /boot is on /dev/sda10. I copied your code and pasted it into the file

/etc/grub.d/40_custom

I am very sorry for all of the trouble over something that should be so easy.

Did you also run update-grub2 or update-grub?

Regards
Elmar

[Brotherred]

I updated-grub2. But just to be sure I went back and update-grub. But those did not work. Unfortunately my partition configuration has changed. I reworking my plop to reflect that.
