As I said in the other thread, you will get suggestions from the preposterous to the well thought out.
1.) Using the Windows drivers to access your Linux file system
2.) Can't copy from/to FAT file systems
3.) Can't copy from/to NTFS file systems
4.) Must use FAT file system to share files
5.) Use NTFS as /home partition so you can share data with Windows
6.) Operate as root so you don't get nag screens. (Haven't seen this one yet in your threads but expect it any time.
Let me try to clear up some of the confusion about partitioning for you. When a hard drive comes from the factory it is not partitioned and has no file system on it. It is all unallocated space. To install any OS or file system on it, it must be partitioned. When you install Windows XP the install disk creates at least one partition on the hard drive and calls it C: drive. If you create 2 partitions the second one is called D: drive by Windows. Windows formats both partitions to the NTFS file system. You Windows operating system is then installed to the first partition, what Windows calls the C: drive.
When you install Linux you have more choices in partitioning schemes and the file systems you can use. You still have partitions, you just call them by different names, ie. sda1 = the first partition of the first, (a), hard drive = C: drive in Windows, sda2 = the second partition of the first, (a), hard drive = D: drive in Windows, etc.
In short, if you can't/won't learn to make a partition you can't install any operating system. Regardless of the OS, you must create a partition and put a compatible file system on it before you can install anything. Sorry, but it is what it is.
