Need to do wipe and clean install on dual boot Lucid/Win7

[Doublehelix22]

How do I do a full wipe of Lucid without affecting my Windows setup? I'd like to do a full wipe and a clean install so I don't make more mistakes

I used the alternate installer CD to set up a dual boot with Win 7, and encrypted Lucid using instructions from the following webpage

http://blog.nyxyn.com/2010/05/encryp...dual-boot.html

Lucid initially installed and worked fine- except that I'd done something dumb and encrypted the home directory as well during the installation and for some reason couldn't access free space

Trying to fix it I made so many more mistakes I broke everything from grub onwards and I figure a clean install is the only way to fly, but I can't find anything too easily which will tell me how to remove Ubuntu from my system altogether ( pref without hurting Windows ). Possibly I have too much information and my head is going to explode

Was using Jaunty a mate set up for me-very happily too- for a year when my laptop broke. I decided to try a similar install on my new machine with Win pre-loaded, I figure if I understand what I'm doing it will help me to get more involved in the community

Hoping this isn't the dumbest question ever

Thanks for your time

Just boot to your CD and when you get to the Partitioning, do a manual partition and set your EXT4 partition as / and your Swap as Swap if you made more than one partition for Ubuntu, post back all your partitions.

Thanks, they'd reverted back to something odd.

Am re-installing, will let you know how it goes

Re-install works well, but I still can't mount my free space- error message shows up as

Unable to mount 219GB LVM2 Physical Volume

I'll have a look around for fixes

thanks

Er... Is it partitioned as anything?

Sorry for the delay in replying there, I thought I'd already replied before

I ended up giving up on this and just installed encrypted Ubuntu, wiping out Win in the process

Full install from CD worked straight out of the box and runs like a top

One day when I have more time I'll try this again but atm am massively enjoying functionality

cheers and thanks!
