The disk drive for /home is not ready or not present

[Dáire Fagan]

Hi

Until recently Ubuntu had been working fine, which I dual boot with working Windows 8 on the same HDD. I have not knowingly changed any of the partition settings unless Windows has somehow although Ubuntu has definitely worked for some time since I initially set up the dual boot.

I found previous threads on the same topic where the original poster was asked to paste the output of fdisk -l and /etc/fstab. Not knowing how to copy text from recovery I took pictures, please see them below and advise:

You can just copy & paste terminal output. Best if longer to use code tags.

fdisk works for MBR but not gpt partitioned drives.
You need to use parted or gdisk. Gdisk is the fdisk for gpt partitioned drives, but usually is not installed by default.
sudo apt-get install gdisk

sudo parted -l

sudo gdisk -l /dev/sda

sudo gdisk -l /dev/sdb

With the 24GB drive is that a SSD and system is an Ultrabook with Intel SRT?

Firstly, sorry for the late reply.

I can use code tags, but I am not sure how to copy and paste when I am logged into a recovery console. I am unable to login normally, unless I log in as guest.

sudo gdisk -l /dev/sda

sudo gdisk -l /dev/sdb

It is not installed and I am not sure how to connect to the WLAN from the command line (if necessary?).

Yes it is, and before some months ago I had it all working dual booting Windows 8 with Ubuntu, the 24GB properly functioning for IRST (Intel Rapid Storage Technology) - confirmed functioning with expresscache.

Something small has obviously changed, considering it was all working, any thoughts? Please advise on the way forward.

I think I need lots of detail.Boot from live installer and install Boot-Repair and post link.

Post the link to the Create BootInfo report. Is part of Boot-Repair:
https://help.ubuntu.com/community/Boot-Info
Boot Repair -Also handles LVM, GPT, separate /boot and UEFI dual boot.:
https://help.ubuntu.com/community/Boot-Repair
You can repair many boot issues with this or 'Create BootInfo' report (Other Options) & post the link it creates, so we can see your exact configuration and diagnose advanced problems.

I only see one ext4 partition, so mounting /home should not be an issue. But some of your screen shots showed sda7 as /home originally. And sda7 is now NTFS which cannot be /home as NTFS does not support Linux ownership & permissions.

Thanks for the quick reply, here's mine:

You reformatted your /home to NTFS.

Current partition sda7
/dev/sda7 BECEB44ECEB3FD29 ntfs


# /home was on /dev/sda7 during installation
UUID=c3784ee9-b776-4afd-a954-e3804235e5c0 /home ext4 defaults 0 2

You have no partition with the UUID of /home.

Ouch. The main docs I wanted from it before reinstalling are in the cloud, I just wanted to check if there were any others. Thanks for your help.
