Re: How to fix corrupted partition from ubuntu?
I've never seen that error but I do see issues. I think you are spending time on something that won't solve your issues.
Do you have anything in the Ubuntu installation (sda7) that must be salvaged? Nothing else in the extended partition shows as being used.
I'd delete all partitions that are within the extended partition. This is sda5, sda6, sda7, sda8. Then delete the extended partition (sda4). Your extended partition shows lba flag configuration. I suspect you installed Fedora at some time causing this but it could have been done in error as well.
I believe that after deleting these partions you should recreate the extended partition and have it use all available space. Then within it create whatever logical partitions you need. You only need one swap, a bit bigger than the amount of memory you have. I prefer to make it last and at the end of the disk but that is just preference. Linux OS partitions should be 15-20 GB if you use separate /Home partitions or a shared ntfs partition that will house your pictures, music, videos, etc. I say a shared ntfs partition so that linux and windows can both get to this. If you don't share data like this you should ensure each OS has enough to store the planned data.
Please see my screen shot that shows what I describe. As you can see I have a bunch of distros but if you won't you'd just split the space in the extended partition as needed.
When all this is done, then start doing installations and make sure you choose to allocate the disc space manually. Currently Ubuntu labels that option as "something else" on the disc allocation screen. If you install Fedora again, ensure that you don't do lba as it will greatly complicate things for you.
