Yes, you can. But no in the same logical partition. But it's not easy, because you will have to edit boot.ini file manually which is not trivial. It's better to install Xp and then Linux.
Yes. This is called "multi-boot" and the de facto standard Linux bootloader (GRUB) is the reference implementation bootloader for this process.
Sounds like a problem with Windows XP. What you should have tried to do is take the original hard drive, put in the xp install disk, to the install, choose to format the hard drive, and then continue with the XP install. BTW: XP > Vista. Linux > XP. You should install Linux, instead of XP.
Supposing that the hard drive is unmounted, you can just install and run gparted or qtparted. If the hard drive is your main hard drive (ie. you cannot unmount it), download a Linux LiveCD, burn it, place it in your drive and restart your computer. Boot from the LiveCD and then run gparted or qtparted. Caution: BE VERY CAREFUL YOU COULD, BY ACCIDENT, DELETE ALL YOUR DATA
Yes, you can. It is known as dual booting. Install Windows first, then any Linux distribution of choice - Ubuntu, Mint, Puppy, and so on) second. When installing the Linux OS, you will be offered either to wipe completely and use the whole hard-drive, install Linux alongside Windows (or the OS already installed), or Custom Install. To dual-boot, choose install alongside...
You can do that, but it's easier to connect the hard drive to a working pc, and clean. It works if you are going to reinstall windows, if you are planning on using linux. Just install it, clean the partitions exactly as you said.
A computer external hard drive is a storage device that is connected externally to a computer. It is possible to learn how to install a computer external hard drive though websites such as eHow, or by attending an appropriate college course.
empty your trash can even Linux distros have one not sure about osx delete or uninstall al unneeded programs defrag your hard drive (this just makes your computer a bit faster) install a new light wheight OS (only if you really don't want to buy an extra hard drive) Linux is great for this
Yes.
You do not need to "initiate" a hard drive. If the hard drive is installed correctly, Ubuntu will detect it.
Yes. To achieve this, you need to shrink the window partition so there is space for the Linux partition on the disk.
Yes. LiveCDs can access the hard drive on a computer, though you will need to know the partition identification to mount that partition.
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.
Format the hard drive, install another version of Windows, or a Linux distribution.
