Removing non-dual boot O/S from partition....

I have a Windows 7 laptop that has 3 partitions on it with only one booting Operating System on the Hard Drive. One of the partitions contains a previous version of Win7 on it that became corrupted and I had to install my current version of Win7 on a newer primary partition which Windows boots straight into.

I no longer need to use the previous O/S and it takes up 17.6GB which I think is now unnecessary to retain (and is hogging up valuable Gigs that I could really make use of due to nagging pop-up that tells me that disk [partition] is running out of space) and would like to know if I can safely remove the old O/S from the partition and still retain the other data on the partition and how I can best go about removing the old O/S?

Hi and welcome.

Please post a screen shot of your Disk Management window so that we can better understand what you have.

Id make a system image and just re-install, as 1 partition.

Thank you for your help, Gents. As requested, here is a screen shot of my Disk Management window. As you can see, I have added notations to the image which I trust will explain things a little clearer?

Yep, backup your data, use a Partition Wizard Boot CD to setup the drive, I too would create a data partition if you only have one drive.

Then reinstall windows.

Do it right, don`t think twice about it.

Clean Install Windows 7

I already have a freshly installed Win7 O/S on my C: Drive AddRAM and it is running perfectly, thank you.
I had to do a clean install of this O/S the the Primary partition on my C: Drive because the original Windows 7 that resides now on D: Old Windows became corrupted and necessitated the clean install onto my C: Drive. It is this corrupted version of Win7 on D: Old Windows that I had to partition and now wish to delete from the the partition but still retain the other data contained on that partition - can this be done?
Also, I am very limited for back up space on the other partitions so can I just delete the O/S files/folder on its own?

Again, my thanks in advance.
