UUID and /home

[Patinio]

Hi everybody,

After crash my grub by taping on windows recovery, i can not mount /home.
My problem is than my UUID is not valid anymore. In fact during the installation i did'nt create a real partition for my /home.


Can i find the good UUID not by (/dev/disk/......) or recover my /home datas?

Thanks in advance.

Not understanding your statement here. Did you do a full Windows recovery which wiped Ubuntu and Grub. If so. Ubuntu is gone.

Can i find the good UUID not by (/dev/disk/......)

In Ubuntu terminal you can find UUID by

sudo blkid

Thanks for the quick reply.

My / and swap partition is OK, i can boot and use it. It's just about my /home.
I Did not create a /dev/sdaXX for, so my /home is somewhere on the / partition. I'm just looking for the good UUID to mount /home.

If you didnt create a partition for /home, then you dont need to mount it. So you also dont need a uuid.
You say, your / is ok. Are you sure you didnt accidentally delete /home?

Other that that, can you post the output of

fdisk -l

No i'm not sure than /home was delete.
I need to mount '/home' because actualy in '/' '/home' is empty.

Thanks.

Again: If you didnt create a partition, then there is no uuid

To clarify that, can you paste the output of

fdisk -l 
and cat /etc/fstab

See below the requested commands

fdisk -l

Ok, there is only one linux partition, presumably containing the system.
What do these say?

cat /etc/fstab
ls -la /home

Your fstab output shows there was a /home partition on sda7 and a swap partition on sda6 at the time of installation. Your fdisk output shows neither of these partitions. If you had created a user patinio during installation your should have seen that in the output of the ls -la /home/ command. Without knowing what happened prior to getting this problem it would be difficult to diagnose.
