Problems mounting partitions while installing Ubuntu

[JohnNicks]

I am using the live CD and haven't installed Ubuntu yet. My computer doesnt want to recognize my Windows partition, and when I run the Ubuntu installer off the live CD it says it can't find an operating system and in the partition area it can't find it.

I want my Win 7 ntfs partition and Ubuntu on sepreate partitions.

Boot the Ubuntu installation medium and run the following command to display drive/partition information and post it here:

sudo fdisk -l

That's a Lower Case Letter L in the command.

Often better to post text or teminal output directly and include in code tags or use # in advanced editor to add tags. Only attach screen shots not in line. Not everyone has high speed Internet and in line can slow them down a lot.

Since you already have Linux partition, just use Something Else and choose the same sda5 as ext4, and / (root). It will find existing swap automatically.
I think even with BIOS/MBR install you may have issues with any of the auto install options erasing drive even if it says it is overwriting just Ubuntu. Something else is a safer way to install.

OldFred, I didn't know how to copy the terminal text.

If I do that something else will I lose my Win 7 partition? After install how can I get it back?

"Something else" is for manually/explicitly managing partitions, instead of the automatisms programmed in the other options that doesn't require user input.
Do as oldfred told you and you won't loose any partitions. However, you should ALWAYS have a current backup and ANYTHING you don't want to loose.

Okay, how do I get my Win 7 partition working after install? Just as a refresh, I can't access it when I boot without the live CD it comes up with a Disk Read Error message as I stated earlier in this post.

I know the GParted app on the live cd has this under the info of the partition:

Failed to load runlist for $MFT/$DATA.
highest_vcn = 0x6a, last_vcn - 1 = 0x138ff
Failed to load $MFT: Input/output error
Failed to mount '/dev/sda1': Input/output error
NTFS is inconsistent. Run chkdsk /f on Windows then reboot it TWICE!
The usage of the /f parameter is very IMPORTANT! No modification was
made to NTFS by this software.

Unable to read the contents of this file system!
Because of this some operations may be unavailable.
The cause might be a missing software package.
The following list of software packages is required for ntfs file system support: ntfsprogs / ntfs-3g.

Why do you need to access your Windows partition from Ubuntu? I mean, there could be several reasons but generally it ISN'T advisable. Also, if you're having issue booting into Windows (that partition), Ubuntu won't magically solve that for you.
The error message mentions a problem with reading that partition and that can have many causes. The usual ones are a) an hibernated file system or b) a corrupted file system. Neither situation is "solvable" from another OS. You MUST boot Windows and, for a) just make sure you shutdown the OS properly, or, for b) use Windows tools to check/correct its own file system.
It should be so hard to understand...

My problem like I have said before, I can't boot into Windows.
