I have my OS on one partition and my data on another, on the same drive.

  1. If I install Windows 7 on the OS partition, will it erase the data partition? I'm guessing not, but this isn't something I want to risk.

  2. Also, how would it treat/what should I do about the XP install currently occupying it?

  3. How much OS partition space will Win7 suck down? The partition is 100 GB.

  1. No, it will not erase the data partition, but it's always good practice to backup your data before doing anything.

  2. Windows 7 will replace XP totally.

  3. A clean Windows 7 installation takes up slightly less than 5GB.

Thanks. :) I'll update after the install happens. – Narf the Mouse Sep 26 '11 at 20:04
