I've just installed Lubuntu 17.10 on my laptop and removed Windows 7. But I can't find my former hard disks (D:\, E:). When I tried Lubuntu without installing ( and deleting the previous os ) I could use my hard disks. But they have disappeared. What can I do?

As @Rinzwind pointed out in comments, you've overwritten your Windows partitions with Lubuntu -- unless you have a backup, all the information that was on the computer is gone. If you have additional physical drives, however, they won't have been touched by the install; you merely need to add entries for them into /etc/fstab so they'll automount when Lubuntu starts. There's documentation available on how to format an fstab entry, and you'll want/need something that will read the UUID from each volume (UUID is strongly preferred over volume label or device notation, as it doesn't change unless the volume is formatted).

  • Do you really mean all the data on the other disks like D:\ and E:\ are gone? Really? How can installing an os remove all the data on my disks. I've got a backup in the disk E:\ do you mean it's gone too? – Mohsen Nirouzad Feb 21 '18 at 17:50
  • If you chose "use the entire disk" when you installed Lubuntu, it did exactly what you told it -- erased everything on the physical disk and automatically created one or more partitions for itself. If you chose "install alongside Windows", then all you need to do is get the UUIDs of those other volumes and add them to /etc/fstab as noted in my answer and the other one. – Zeiss Ikon Feb 21 '18 at 18:22
  • Sorry for asking too lot i'm very nervous, but I had three hard disks and only one of them (C:) contained the windows files. I chose "use the entire disk". Do you mean that the D:\ and E:\ disks are also erased? – Mohsen Nirouzad Feb 21 '18 at 18:27
  • Were C:, D: and E: three real physical disks or were they partitions on one single physical disk? – muclux Feb 21 '18 at 18:32
  • "I chose 'use the entire disk'" -- that means anything on the physical disk that now contains Lubuntu was erased. Information on other physical drives should be untouched, but those volumes won't automount until you manually add them to /etc/fstab. If your C, D, and E partitions were all on the same hardware device, they're all gone. If not, the ones that weren't on the "first" device (as seen by the Lubuntu install media) will be fine. – Zeiss Ikon Feb 21 '18 at 18:32
  • Three partitions of the same disk. Now I understand. My data is gone. thanks for replying me... – Mohsen Nirouzad Feb 21 '18 at 18:34
  • I'm sorry to hear that. For future reference, this is why it's not a perfect plan to keep your backup on the same physical device as the data it's supposed to protect. User errors aside, if the device fails, the backup is gone, too. – Zeiss Ikon Feb 21 '18 at 18:35

First of all, Install a utility such as gparted . It will scan your hard disk and you'll come to know if those partitions exist in the first place or not.

If they exist, select the partition you want , right click and select "Information" There you'll get the "UUID"

Now you'll need to add entries to fstab.. follow this guide HERE
