I am looking for the best way to create a dual boot on my Red Hat system.This is a Red Hat 5.3 System for scientific use, and we need to run some Windows software on it for visualization purposes.What is the easiest way to implement dual boot if Linux is already installed; formatting the hard drive is not an option.My thoughts were:Partition the HD and give Windows a 200GB logical driveInstall Windows 7I am probably missing the part where I configure the boot loader.What is the best way to do this?As a side note, is there a way to virtualize (VMWARE like) Windows 7 on the Red Hat machine and if so, will that cause a BIG loss in performance? And if so, how much do you think it will be?

After installing Windows, you will need to boot of some linux recovery disk if you wish to re-install + configure grub for booting.Otherwise, you could look into EasyBCD which edits the Windows boot system to enable you to boot Linux from windows's boot loader instead.As far as virtualization is concerned, there are several options (depending on the CPU in the machine, and how serious you are about it)You could look into VMWare, VirtualBox, Xen or KVM which can all run Windows under linux. The last 2 require VT-x/AMD-V CPU extension support for Windows VMs, and all 4 will run smoother if the CPU has the virtualization extensions.The only really loss under a virtual machine in graphics performance because none are capable of properly emulating a graphics card in realtime (Though Xen has made some progress on GPU passthrough).So, it depends... :)
