Replacing Ubuntu 14.10 with 14.04 and it can't boot now


Hi all, I was trying to install Ubuntu 14.04 to my machine, which ran Ubuntu 14.10 and Windows 7 before. After choosing 'Delete Ubuntu 14.10' in the installation guide, three new partions with strange names appeared. Now it cannot boot, but shows 'grub emergence' something.

'sudo fdisk -l' inside the live-os gives the following:
[update] #8 is a screenshot of the Gparted information.

[end]

The three "/dev/mapper" are the said new partions.
Any suggestions? I have no idea what is happening here, and what to do next. Thanks!

You have a lot of partitions!
Are you trying to install to sdc (your third disk)?

The reference to /mapper/ means that you are using LVM - possibly as encrypted partitions???
If you don't want this, just delete those partitions from sdc before installing Ubuntu.

I'd suggest that you tell the installer to put use the MBR on your boot disk - which is likely to be sda.

Take full backups of all data everywhere.

I'd suggest you spell out carefully what you are trying to do, first.

Oh, sorry, that sdc is a removable disk (a WestData Passport). After unmounting it, the fdisk output is essentially the same.

Also, I should have mentioned that fdisk also printed three error messages to the screen:
[begin]
Disk /dev/mapper/fedora-swap doesn't contain a valid partition table
Disk /dev/mapper/fedora-home doesn't contain a valid partition table
Disk /dev/mapper/fedora-root doesn't contain a valid partition table
[end]

I am pretty sure that /dev/sda9 is the physical disk that the 'fedora-' ones point to, because its size equal to the summation of the three 'fedora-' disks' size. I really have no idea why 'fedora' appears (a revenge for my replacing it with Ubuntu 14.10 a month ago?). I tried to free /dev/sda9 and install Ubuntu on it but failed.

All I want to do is to install Ubuntu along with Windows 7... Those with 'ntfs' format are surely my windows' disk; it won't matter to free all other disks. But 'fedora-' disks couldn't be freed -- there's no such option. So the key problem for me may be how to get rid of these 'fedora-' thing.

Hi:

Ubuntu 10.04 End Of Life (no longer supported) was in May of 2013.
http://fridge.ubuntu.com/2013/05/10/...on-may-9-2013/

The current version of Ubuntu is 14.04 (Trusty)
http://www.ubuntu.com/download/desktop

***It's best to run a distribution that is supported.***

You have so many partitions that it might be a good idea to use g-parted and repartition what you do have.
I'm pretty good with partitioning but this is out of my reach.

-:-I think your going to need one of our members with advanced skills in multiple partitioning tasks.-:-

Boot Info Script is a bash script which searches all hard drives attached to the computer for information related to booting. Its primary use is for troubleshooting booting problems.

I suggest you download it so the member that helps you with your partitions can help you.
http://sourceforge.net/projects/bootinfoscript/

Gparted information


The following link doesn't work. Pls check #8 below for the screenshot.


I installed gparted, and could see the partition table with:
/dev/sda1 fat16
/dev/sda2 ntfs
/dev/sda3 ext4
/dev/sda4 extended

Under /dev/sda4 there are several logical partitions, including
/dev/sda5 ntfs
/dev/sda6 ntfs
/dev/sda7 ntfs
/dev/sda9 lvm2 pv
/dev/sda8 linux-swap

I am now trying to release /dev/sda9 and see what happens next.

That link doesn't work for me.
I just get a blank page that say "403 Forbidden"

You could open g-parted and take a screenshot and post it on photobucket and just supply the link for us to see.

Or you could click on 'Manage Attachments' under the post that you make.
It's under the submit reply button and preview post button in "Additional Options"

Hi John, could you see the screenshot in #8? It's more clear. Don't know what fat16 is doing here. Supposely some small but important chunk of data stored there?

Solved now! I deleted the fedora disk from Gparted. And then the fedora-xxx things disappear and the installation this time finished with no problem.

Many thanks!

To Ztcoracat: I did make that mistake... I editted the post and corrected them Thanks!

Your Welcome!-

Was that a Windows 95 partition?
