The only way you can load Linux with XP is if you are using a shell program, or you have partitioned your hard drive into multiple partitions and you are making a dual boot machine. That's not something I suggest for the computer illiterate.
I use 4 GB of RAM so 512 MB is about enough to load XP and that's about it. I'd recommend Linux
Yes.
Yes Linux can be installed on the same computer.
Yes. If it's already installed, merely point your bootloader to your Windows XP partition/hard drive. If it's not already installed boot the computer with a Windows XP install disk and follow the instructions. Note: Microsoft will be discontinuing support for XP soon, may want to choose a more up to date version.
Windows XP is not in the direct upgrade path of Red Hat Linux 8.0. If you want to install Windows XP on a computer / server with RHL, you need to check the hardware specifications to see if Windows XP supports it.
There is no such thing as "Linux XP". If you're referring to Windows XP, then the answer is no. As far as Linux distributions, for the majority of distributions, they are free (as in freedom) and free-of-charge.
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.
You can install and run Microsoft Office in Linux, yes. You will need to install it separately, however; you can't just run the programs off your Windowspartition in Linux.
Linux XP is a shareware Linux distribution which seeks to offer a user interface similar to Microsoft Windows XP. Unlike most Linux operating systems, Linux XP is offered as a 30-day trial after which the OS will disable itself until it is registered. It is currently owned and being developed by the Trustverse company based in Moscow, Russia.
Before you format xp you will need to go onto Linux and create a grub boot disk by typing grub-install /dev/fd0. This will create a floppy disk which you can use to start Linux after you have removed and reinstalled xp. After removing and reinstalling xp use the disk to get back onto Linux and use grub-install /dev/hda to restore the Linux boot screen.
Normally, the computer will not boot. And you will have to reinstall Windows XP.
Make sure that you have installed the Samba client package on your system.
