The one that got my attention was the second one, which has been cleaned up since the original post. Thanks to the OP, or whoever did that.

step by step would be a better given solution IMO aka mounting then passwd etc...

OIC -- been removed has it, no wonder it's causing me confustion... I'm ok now .. thanks

Step-by-step
works for LinuxMint also.

Thank You @Habitual

Actually I remember doing that, and it ended up not working.

does MINT got a GUI install where you can wipe out the Old Linux Partitions, then set up new ones? it Better should have, the just partition a / and /home then do Install OS then grub install mbr then -- boot mint then open Term then sudo update-grub or sudo grub-install /dev/sda then update-grub to be sure it is all good and it should pick up Win7 on the grub-update.

It has a LiveCD so I can use it before installing it. If that's what you mean, then tell me what to do. Step by step please.

I'm Downloading that ICO as I write this to check it out in VirtualBox,, get back on that as soon as I get it. Mint 'Cin a min" is the one I picked.. they all should be the same.

It's what I thought, it's like Ubunututututu .. when you click on install, then get to this takes you to a GUI to delete old partition then you can rereate it again. it is rather simple Just read this it even has pictures for your viewing pleasure.

So yeah it doesn't say what to press to delete it. On a second but unimportant matter I am going to bed now. I will answer you again tomorrow.

you have to use that arrow thingy to click on what it is you want to get rid of. Don't be scared to fiddle around just cautious, you have to find the partitition that you installed your linux distro on, select them or the one you used then select dlete and yes, then select that empty part you'll then have then create the new partition, ( this is in leu in just selecting it then - checking that box to just have it format it instead, while you have mount point as / )

just re-create your partition again mount point / ext4 or what ever you want it to be. then confirm it so it will write it to the disk. then you can procced.

I hope that'll help --- the install is just like Ubuntututututu

Since you're learning, have already had problems and don't have a disk to reinstall windows I suggest before you go further you back up your current installation to an external USB hard drive using something like redo backup.

This will free you up from the worry of making things even worse b/c if you blow up the current broken config by mistake and completely break it by doing something like deleting your windows installation you can just load everything back and try something else until you get it fixed.

Plus, once you get it fixed you can also use the same software to back up the fixed configuration to an external drive so that if it ever blows up again, whether from a mistake or a virus, you've got a copy of your OS that can be used to fix the system; since you don't have an installation disc for windows.
