I have Ubuntu 12.10 on my laptop, no Windows.
I have my system disks and tried to do a system recovery and it won't allow me.
I've tried creating a boot disk and doing the "try ubuntu" and installing the OS uninstaller.
My laptop freezes up in this process.
Any other suggestions on how to remove ubuntu and reinstall my windows vista again?
Just get Windows Vista DVD.
Boot into Disk (Check mobo documentation for booting into dvd).
Follow on screen instructions provided by Windows Vista installation interface.
When comes to partitioning Hard Disk - Delete all partitions and install a fresh copy of windows.
Try booting into your Ubuntu Install Media.
Go through the installation process until you get to where you want to install it.
Format your hard drive(s) from there.
Profit.
Or, just boot into Recovery Mode. https://wiki.ubuntu.com/RecoveryMode
You could also use Gparted - partitioning tool ( on normal or failsafe mode ) , it's just amazing !
You could do all the operations on manual( advanced mode), with Gparted you could even create the future EXT4 partitions on which you plan to reinstall Ubuntu, you need a / partition (I'd give atleast 20 GB ) a /HOME partition (or use the one you already have) and a SWAP partition( I would size it to 1 GB).
English being my third language I didn't noticed that you plan to dump Ubuntu :) . I had some issues with my toshiba laptop ( and the shitty i3 integrated everything) and previous ubuntu versions but I'm all excited about the new Ubuntu 14.04 and hope that the drivers would work better and my laptop would stop behaving like a fan :)
