Today I went to resize one of my drivers partitions as I am currently switching from Ubuntu to ArchLinux as my main OS. However when I go into Gparted I get the error "Cant have overlapping partitions". Checking Fdisk gives the below resolt:

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *        2048      206847      102400    7  HPFS/NTFS/exFAT
/dev/sda2          206848   318586879   159190016    7  HPFS/NTFS/exFAT
/dev/sda3       770101248   976773167   103335960   83  Linux
/dev/sda4       318588926   770103295   225757185    5  Extended
Partition 4 does not start on physical sector boundary.
/dev/sda5       318588928   770101247   225756160   83  Linux

Looks like sda4 is overlapping with sda3. I know my partitions are a big of a mess, one of the reason I am moving from Ubuntu so I can remove the sda4 and 5 leaving just Windows (sad1+2) and arch linux (sda 3).

So I guess my question is how to fix this overlapping. if possible by shirking sda4/5 so there is no longer a over lap?

I would prefer to keep retain my data but everything is backed up so if there realy is no other option I could to a complete clean install... but why I am here is to see if there is anything way first.

Thank you and if you need any more info let me know!

If two partitions overlap, then very likely you don't have any data to keep anymore, since writing to sda5 will corrupt data in sda3 and vice versa. – grawity May 19 '13 at 10:38
Well this is the odd thing, if you look the partitions /sda5 and sda3 do not over lap its the extended partition that does, and the bit that is over lapping isnt actually being used in sda4. I still have access to all the date on both sda 3 and 5 and its quite possible its been like this for at least a week since I isntall arch to sda 3 – Zac Powell May 19 '13 at 10:51

Try my FixParts program. It should fix the problem automatically. I recommend launching it on the disk and using FixParts' p option to view your partition table. Note that FixParts doesn't show extended partitions at all, so don't worry when you don't see your /dev/sda4. If you see all the other partitions, though, and if none of them is listed as omitted in the Status column, go ahead and type w to save the repaired partition table.
