Re: LL2 not booting if one extended partition is formatted to FAT 32 - arunp - 08-24-2014

Dear gold_finger,

Thank you for all posts and patience to my queries. but the fact i want to communicate to you is fact and reality of what is happening on the system, I am to aware that that in the terminal it shows the NTFS partition recognized but the reality is it is not appearing in the File manager or on the desktop screen, here is the screen shot side by side showing the terminal out put and file manager not showing the NTFS drive.

The same is true that it doesn't boot if configured in the original fashion advised by you.

gold_finger i wanted to assure you is that i sincerely wanted to use LL and distribute it among my friends here when i started that the first hindrance i faced was this i.e. they wanted one common drive partition in the portable drive where the files in this drive can be read when booted with windows and also with LL when it is booted with LL.

If i am facing this problem any body trying in this combination will definitely face this issue, I am putting all my efforts to support the LL team to put on a robust system which i am sure will once dominate the desktops. I request you if you don't trust my posts pl try this installation your self on a portable drive and if it works fine with every boot just post back one line, "it works fine" else we will continue to work on it still we put a robust LL to the world.

I sincerely apologize if my post has offended you.

Now on will continue to Post only what is requested by you.

Re: LL2 not booting if one extended partition is formatted to FAT 32 - gold_finger - 08-24-2014

You did not offend me.  The problem is that since you are new to Linux, you don't know what to look for and sometimes there are terminology mix ups.  What you describe one way, people who have a Linux-based mindset might interpret as something else from what you actually meant.  In my posts I was trying to find out certain things that would divulge whether it was just a simple misunderstanding or not, but you kept trying new things on your own and those new things ended up making my questions useless.

I now see what the problem is.  You are expecting to see the NTFS partition in your file manager under either Devices, Places or in the Home folder.  That is not where it is going to show up.  When a partition is mounted to a particular spot in the file system it will no longer show up under Devices or Places.  And it won't show up in your Home folder either unless you made the mount point in the Home folder.

In your last screenshot, to find the NTFS partition you need to go to where you mounted it -- in /mnt/Windows.  Open your file manager and click "File System" under Devices.  That will put you at the root of the file system (at "/").  On right side you will see a bunch of folders.  Click on the "/mnt" folder.  Then click on "/Windows" and you will be in the NTFS partition.  Try to create a folder in it.  Let me know if you are able to do that, or what happens when you try.

P.s.  If the system does not boot I have no clue what could be wrong with it.  I've never heard of that happening before.

P.s.s.  Assuming that you still have system setup as per latest screenshot and that the system does currently boot up properly, do the following to make the /mnt/Windows partition show up in your Home folder.  Open a terminal and enter this command to create a symlink to the partition.  Substitute your actual username where I have "username" below.

Code:
ln -s /mnt/Windows /home/username


Re: LL2 not booting if one extended partition is formatted to FAT 32 - arunp - 08-25-2014

Dear gold_finger,

Thank you for your patience and the excellent reply  Smile, it worked perfectly and the drive is showing up, but not under devices, directly under File system as "mnt". I could create the link to home folder as instructed by you.

Now we need to look at our old problem, "LL is not booting". I will reconfigure the system to old partitions and install and post the outputs as requested by you in reply on 23rd Aug.

Once again thank you for your excellent support

Sad  I don't know how much help I'll be but I'll try anyways.

I am fighting my own /dev/sdb. I have it hooked up via adapter cables. The device is a 16gig SSD removed from my Acer C710 chromebook.
It acts flaky as hell. It wont show in fdisk -l, parted -l, sudo gdisk -l. example:

Code:
# fdisk -l

Problem opening /dev/sdb for reading! Error is 2.
The specified file does not exist!

So. I used a gparted live cd ver 0.19.1-1.i486 and booted it. I got it to see /dev/sdb. I assigned a partition table and told it to be GPT. I hit apply. Done. I then made a new partition and told it to be ext4 and labled it as / (root). Apply and done.
Gparted live iso shows my 16gig ssd as / formatted as ext 4 as a GPT drive.

But. Becuase the hard drive is flaky. I have to look in
Code:
# dmesg | tail

Because I still can't get the durn thing to be recognised even then. So probably a hardware issue.
Anyways. Since you asked. Maybe try

Code:
sudo dmesg | tail

instead of

Code:
# lsblk
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 298.1G  0 disk

└─sda7   8:7    0   3.9G  0 part [SWAP]
sr0     11:0    1  1024M  0 rom

Because as you can see. dmesg can see my /dev/sdb when nothing else can.
HTH. Like I said. My chromebook is dead and I am fighting with its hard drive myself.
Just stepped in because I was asked. I don't know how much help or not this gives.

Happy Trails, Rok

Oh yeah. Since we are talking Windows File systems here.

Code:
apt-cache policy ntfs-3g

And was a md5sum done of Linux Lite 2.0 before installing?

Re: LL2 not booting if one extended partition is formatted to FAT 32 - arunp - 08-29-2014

Dear gold_finger,

I reinstalled LL with our original configuration (sorry partition sizes got changed) and posted below the out puts as requested from your reply #17 and also the out put from other commands posted in your earlier output. The problem remains the same, when booted the Grub blue screen runs and after the defined 10 Seconds it goes blank, does not start OS.

Re: LL2 not booting if one extended partition is formatted to FAT 32 - gold_finger - 08-29-2014

arunp,

From what I see, everything looks to be in order so really don't know what is causing the problem.  At this point, I can only make wild guesses as to what's going on.

A few weeks ago on a different forum someone else was having similar (not exactly the same) problems with booting.  Went back and forth trying various things for over seven pages thinking that the person must have been doing something wrong.  In the end the cause turned out to be something nobody suspected and we discovered it virtually by accident -- his keyboard wasn't being read properly on boot-up.  Maybe something obscure and silly like that is going on with you.

Since you appear to be partitioning and installing everything correctly, I can only guess that there might be some kind of miscellaneous hardware issue going on.  So, let's just run through some things to check.

1.  Is your monitor connected directly to the computer, or are you using some type of adapter or switch between the monitor and computer connection?

2.  Is your keyboard connected directly to computer, or are you using some type of adapter or switch between it and the computer?

3.  Do you have access to another keyboard that you can plug into computer and try?  (Can you borrow one to test on your computer from a friend, relative, or from work?)

4.  Check all connections to make sure they are not loose -- either where they are plugged into back of computer or where they are connected to your peripherals.

5.  Open computer and check that all connections are secure:
  • check that RAM are firmly seated in their slots
  • check cable connections between hard drives and motherboard
  • check cable connections between DVD/CD player and motherboard
  • if you have a graphics card, check that it is firmly seated in its slot

6.  If none of the above help, report back with exact brand and model # of your computer, your monitor, your keyboard and your mouse.  Maybe we can do searches for those to see if there are any reports of strange Linux issues with them?

Unfortunately that's all I can think of right now.  Countless people use NTFS and FAT32 partitions with Linux without issue, so I seriously doubt that is the cause of the problem.  It must be some other miscellaneous thing causing the problem.

Dear gold_finger,

I am using a Dell Vostro 3400 Laptop, Every thing is working fine with this as the same laptop works fine when i boot with windows and also LL configured as i posted in my reply 24th Aug 14, this reply also i am typing with LL booted and from Firefox browser in the below configuration

arunp@arunp-Vostro-3400:~$

This issue happens only when an extended partition is configured with ext4 (sdb6)for /home along with an extended NTFS or FAT32 (sdb7)format for /Windows.

Is it possible anybody in your team can try installing in this configuration and figure out what's the issue.


Re: LL2 not booting if one extended partition is formatted to FAT 32 - gold_finger - 08-29-2014

Didn't know you were using a laptop.

Since this is such a weird occurrence and it appears that you aren't doing anything wrong, I'm going to install as you did to a spare computer and see if I run into same thing.  Will post back later with the results.

Re: LL2 not booting if one extended partition is formatted to FAT 32 - gold_finger - 08-29-2014

Sorry arunp,

I'm fresh out of ideas.  Did test install on a spare laptop and everything worked without any problems.  Here is output from the test:
