I would suggest installing windows on one hard drive, then installing ubuntu on the same hard drive. Use the other hard drive for the backups (partition it).
You would need to create a partition to install Windows to. Or you can run it in a virtualized environment using Virtualbox by Sun Microsystems. With virtualization you can run Windows or another operating system (OS) of your choice on top of Ubuntu. Of course with either method you will need an install disk of Windows. If you choose to do what is called a "dual-boot" from what I described earlier, you will like I have stated, create a partition into which you will install Windows to. Be careful though when you are working with partitions as it is best to backup all of your data in case of complications. To create a partition from within Ubuntu you may use a program called Gparted. You can install that through your "Applications" -> "Add Programs".
Ubuntu is safe. The majority of viruses and other malware on the internet are written for windows, so they wouldn't affect an Ubuntu computer. However, ubuntu is less user friendly than windows, so I would be careful and make sure you have a good backup for your windows computer.
There is no easy way to "switch" from one operating system to another. The easiest thing is to install Windows 7 over the Ubuntu installation if you do not want Ubuntu anymore. Back up any data you have first before you do this because otherwise it will be lost in the install process.
If you have installed ubuntu with windows you uninstall it in the add remove programs.
If you have a lisenced installation disk you have two simple options: 1. Install it in a virtual machine through virtualbox. This makes it so you can (and must) run both systems at the same time, but switching is faster. 2. Back up ubuntu onto another storage device, such as a external hard drive. Then install windows, and make sure to wipe the system in the process. Then install ubuntu over windows, rewriting the mbr to use the GRUB bootloader. You can replace your files from the backup.
The GRUB bootloader gets it's menu off of the Ubuntu partition. Since you deleted the Ubuntu partition, it can't read the list or know what to do next. You have two options:1. Reinstall Ubuntu.2. Boot from the Window XP CD, access the Recovery Console, and runfdisk /mbrThis will rewrite the Master Boot Record, and shouldallow you to boot back into Windows.
Installing Ubuntu on Windows 7 is easy.One of the steps include formatting your hard drive, make sure that back up you files before installing Ubuntu.To install Ubuntu on Windows XP, Vista 7, follow these steps:Go to www.ubuntu.comDownload the Ubuntu ISO Image and save it to (If your computer is 64bit, download the 64bit version.)Burn the ISO Image to a DVD or a CD.Shut down the computer. Make sure that you keep the CD or DVD inside.Boot from the CD or DVD. (Hit any key before it boots from the hard drive.Select "Try Ubuntu without making changes to your Computer".Wait until it loads up the desktop.Then, there should be an icon that says "Install Ubuntu". Double click that.Fill in the information that the installer asks you.Then it asks you for where to install on the hard drive. If you want Windows to be there after the installation, let it make another partition. If you do not want Windows 7, select "Erase and use the whole hard disk"Wait until it finishes.When it finishes, reboot the computer.During the reboot, it asks you to eject the disk. Eject the disk and hit space-bar.DONE!
Backup and Restore Feature in Windows 7 creates safety copies of your most important files. Let Windows choose what to back up, or pick individual folders, libraries, or drives. Windows can back up files on whatever schedule you choose. Just set it and forget it. In Windows 7, you can back up files to another drive, your network, or a DVD. Backup and Restore for your personal PC and attached DVD or external hard drives comes with all editions of Windows. If you want to backup to a network location, say on your company's central server, network attached storage, or another computer on your network, you'll need Windows 7 Professional or Ultimate.
There is no version of Windows specifically created for Macs, but any recent version of Windows can be installed on a Mac with an Intel processor. Transferability of files hasn't been a problem in a long time. There are many options for transferring files, such as external hard drives or USB Flash drives, CDs, and network shares.
It does - at least it does on my Toshiba laptop. I have an old laptop drive that I now use as an external back-up drive. Windows 7 recognises it as soon as I plug it into a USB port.
USB 2.0 drives will fall back to USB 1.1 speed if plugged into a USB 1.1 port. Windows 98 contains no driver for USB Flash drives by default, but a generic one can be installed. These will work with almost any drive, regardless of rated speed.
No.
