Re: dual installation with Windows 7 - hard disk question
Some folks have been extraordinarily luck and not had their Win7 installs get corrupted when they used the Ubuntu installer or Gparted to mess around with their Win7 partitions. Problem is, if you have a lot of time and effort invested in Win7, relying purely on luck is a really risky way to install Ubuntu. If it fails, as it often does, you will have a very difficult time repairing Win7 to get it working again.
The SAFER way to do this is to use ONLY the Win7 Disk Management tool to mess around with Win7 partitions. It's primitive and kludgy, but it won't damage Win7 in the process. And, after you do the shrinkage, be sure to boot into Win7 a couple of times to allow it to do any filesystem adjustment it needs.
Also, while in Win7, do yourself a favor and use the Win7 Backup feature to create and burn a Win7 Repair CD. That will prove invaluable later if you need to repair Win7 from damage resulting fom the dual boot installation.
