There are a few options:
1. Continue to use Linux.
2. Format the hard drive and install Windows again.
3. Use a LiveCD that includes a program called "TestDisk." This program can sometimes recover deleted partitions and retrieve lost data. You may still have to reinstall Windows, but it will help you retrieve data.
I suggest installing Windows, and then Linux (preferably on different physical hard drives). When Windows is installed it tends to overwrite the boot partition, making it difficult to boot linux afterwards.
you can partition the drive.. to use both OS
Yes. All that you need to do is shrink the Windows partition so your Linux partition can fit. Then just install the Linux OS into there, and you'll be able to choose which one to boot into on startup
Yes. To achieve this, you need to shrink the window partition so there is space for the Linux partition on the disk.
Yes. All you have to do is give Linux its own partition.
Some manufactures put a special partition for restoring purposes. It might happen that windows will not recognize that partition but it will still work with properly. Also if you have Linux on your system windows will not recognize too...

Unless you already have a free partition on your hard drive or an additional hard drive, you cannot install Red Hat Enterprise Linux without "disturbing" Windows; you will need to resize the Windows partition to make room.
There is no set amount of time. It can vary tremendously, depending on the type of partition, the size of the partition, and the speed of the computer.
There are programs you can download that will read Linux file systems. Common file systems are ext2 and ext3.
There are two ways of doing this:Use a virtualization program such as VirtualBox to install run Linux and Windows side by side at the same time.Partition your hard drive and install Linux to an empty partition to set up a dual boot partition. Be careful with this option; you can damage your files if you make a mistake, but you'd get much better performance than if you took option one. See the related links for a good guide on how to do this.
Insert your Windows CD or DVD and get to the part where it shows all your partitions and delete the Linux partitions. If you are unsure which one is your windows partition just make sure you don't delete or format any partition that is in the NTFS, or in the rare case a FAT32 format, as those would be your windows partitions.
