Hello everyone, I am currently using Server 2003 SP2 and have now downloaded the Server 2008 RC. I tried installing it several times, It disables the Upgrade option and when I choose Custom, it says cannot install windows on this disk. Driver needed [Primary IDE Channel]. How do I go about theinstallation?

Try to boot from DVD and format your existing drive Deli

Hello Jash, The upgrade options is disabled if you don't have an enough space in your system partition or if your partition File System is FAT 32, the 2nd reason can also prevent your from make a custom installation. So, check your file system in your system drive and make sure that's NTFS.
