This is my first post on this forum. Thank you for your time and help. I have the Windows 7 Beta disc and I am trying to create a partition and install it on my Dell Vostro 220 (see my profile for full PC details). I have 3 partitions: FAT16 - Primary - 70MB FAT16 - 0xDE (EISA Configuration)OS (C) - Primary, Active - 152.2GB NTFS (Windows XP Pro)NTFS (F) - 80.61GB NTFS (Empty)I am trying to install Windows 7 on partition 3, but the installation is giving me an error: "Windows could not update the computer's boot configuration. Installation cannot proceed." Here's my procedure: Insert CDRestartBoot from CDStart Installation"Custom (Advanced)" InstallationCreated new partition on unallocated space (currently partition 3 NTFS)Copying files...
