Linux Mint doesn't recognise my partitions

I tried installing Linux Mint and it seems that it doesn't recognise my partitions.

I already have windows 7 installed and created an addition partition just for Linux. But it seems that it can see only `free space`. I don't want to format to install linux.

I tried to install it as an application and I keep getting the error "no root file system is defined".

Any thoughts?

Look under advanced options, been awhile since I installed mint, but I always found it friendly. If it doesn't see any partitions then what filesystem are you using?

Linux (usually) needs at least two partitions to function - one for file system, one for swap. A MBR (basic) -partitioned hard disk can have max of four partitions, and you already are using three (providing that you have allocated F: partition for Linux).

So - delete F volume, and shrink the primary partition to cover just the Windows volumes. Then, create extended partition, and make Linux use that for swap and root.

It's without saying that you have backup of your data off that drive, don't you?

I am having the same situation. What people are failing to realize is the advanced installer menu does not recognize any of the partitions on the hard drive. For example I have already resized my windows partition and it boots flawlessly and created a blank partition I intended to install mint to. The advanced partition options does not show the existence of my 650 gig windows partition nor does it see a empty 350 gig empty space. It shows the entire hard drive as empty. The only available option is suggests is formatting the entire drive. My windows partition is backed up but with out the partition manager able to recognize any of my parititons its a guaranteed total wipe and I didn't make back ups so I could be purposefully stupid. "sudo os-prober" does see my windows 8 installation though if I use live. Attempts to update grub fail via sudo update-grub. I'll have to get back with the exact error message The problem exists in the stand alone installer as well as live was not my original option.

What he is saying is that the hard drive does in fact have partitions, it boots. stand alone grub disks see it. The mint installer does not.

I had this same issue. This is often due to residual GPT partition data on a drive using mbr... gparted can only see the corrupted GPT information... overlooking the mbr data. Here is a walkthrough on how to purge this data, http://www.rodsbooks.com/gdisk/wipegpt.html Gparted should have the ability to detect this automatically...
