Ubuntu installer cannot see my partition and Fixparts does not work

[dhruba1]

I tried to install Ubuntu before and managed to do that easily alongside with Windows 8, but then I had to delete that for some reason and now I cannot install Ubuntu at all. The previous version was 13.10 and now everytime I try to install any version of ubuntu it cannot see my partition. I Googled a little and found out the fixparts tutorial, but in my case the return is
"Warning: 0xEE partition doesn't start on sector 1. This can cause problems in some OSes."
but I was supposed to get a prompt about cleaning my stray GPT data. Can anyone help me?

I am using a first generation core i3 laptop. As a noob here I do not really know what I should have included with this problem

dhruba1; Hi !

Windows is not in my sphere of interest, but to nudge this along;
Windows 8 = UEFI and you need to download and install some additional tools to look at the hard drive.
Boot up the install DVD -> "try ubuntu" mode; -> terminal.
Install gdisk:


sudo apt-get install gdisk

Post back the out puts of terminal commands:


sudo parted -l
sudo gdisk -l /dev/sda

As a place to start looking.


when we know more



can advise better

I have just downgraded to windows 7. I will soon post the results after restart. Thanks for your interest to help :)

Did you install in UEFI boot mode or BIOS mode mode?

If drive was gpt and you reinstalled Windows in BIOS mode it does not correctly convert drive to MBR(msdos). Post commands suggested above by bashing-om.
Windows only boots with UEFI from gpt drives.
Windows & Ubuntu only boot from MBR drives with BIOS.

Here is what I got. I do not know much about UEFI and BIOS but I guess it is in BIOS mode given my laptop is 4 year old. I guess I have leftover GPT data, but fixparts cannot find that

It looks like this is the error?
Error: Can't have overlapping partitions.

And running fixparts may have converted to gpt not remove extra old gpt data.
If system is 4 years old you probably did not have gpt partitions.

What should I do now? With this I will never be able to install any version of Ubuntu :(

[Bashing-om]

dhruba1: Hello,

Not a hopeless situation by any means.

What I would do:

I would wipe that disk, and start all over.
Install Windows ->
In Windows run defrag a couple of times AND then in Windows shrink the Windows Partition to make room for ubuntu to be installed onto, There are a couple of methods. In that legacy partition scheme one can only have 4 primary partitions, now one of those primary partitions may be allocated as "extended" and within this "extended partition" one may have as many logical partitions as one desires. ubuntu will happily install within that "extended partition". When done with the Windows partitioning - set up, in Windows run check disk to make sure windows is happy happy. IF there are but 3 primary partitions (not likely) you can make an "extended partition" for Ubuntu. The ubuntu install requires a minimum of 2 partitions, One for '/' (root) and one for 'swap'. Once you are in the ubuntu installer choose "something else" and direct the installation to the partition that you have prepared ( ubuntu: terminal command 'sudo fdisk -lu' so you know what partition is for ubuntu).

The easier solution is to wipe that disk, re-install Windows and in the ubuntu's installer, choose the option "install along side" and let the install wizard take care of all the details. If the install wizard sees that it can install. Else the above will need to be done.

If you are the more comfortable you may post back - after Window is re-installed the output from the ubuntu liveDVD of terminal codes:


sudo fdisk -lu
sudo parted -l
sudo parted /dev/sda unit s print
To show us the current disk layout and a continued discussion of your options to install ubuntu and keep Windows.



we will keep plugging away


'till the deed is done

wiping the disk is not an option for me.. otherwise I could format and partition the whole hdd from the Ubuntu setup. The setup sees my hdd as one unallocated disc and wants to partition and format the whole thing

dhruba1; Welp;



Error: Can't have overlapping partitions.


I do not know what else can be advised.



sometimes I wonder



othertimes I just do not know
