Boot or run windows XP on Linux are in separate disks without virtualitzation
 

I've lubuntu and windows on two separate disks and they boot separately. I boot on Linux for chrome webbrowser but when I need 'my old school' programs I boot on windows. However this is a bit annoying. Anyybody knows how on Linux, a way to boot the windows disk into a separate Linux window? like if I were on a remote desktop, I've heard about the 'user mode Linux' but I don't know if it's able to do that purpose. The easy way of my purpose is to clone the windows disk on vhd and run VMware. But I'm looking for any other solutions. Any a new idea would be appreciated. Thanks

Yes, look at running a virtual machine. Run linux in windows or windows on a virtual box in linux.
Is the machine a BIOS or UEFI machine? What bootloader are you using. You can make an entry in grub.conf to boot both OS's for example.

Have the same setup and I am looking for the same solution. I haven't been able to boot a VM from the Windows hard drive in Virtualbox, somehow I can not get to connect a VM to the Windows drive.

Does anyone knows wheter it is possible?

There is a way to run linux within windows but I haven't used it in years. Co-Linux http://www.colinux.org/

Separate operating systems need to run on separate hardware, so concurrent operation requires either two machines or one machine with real and virtualised hardware.
My personal choice is to have Windows XP running in a qemu VM under Linux. For file access outside the VM I run Samba.
qemu is tedious to set up without a GUI manager, but does not break on kernel upgrades, unlike VirtualBox.

I prefer to run my OSes on the rails. I don't care for virtual. I run Slackware as a main OS, but have a Win 7 installation on a separate disk. I allow LILO (Slack's bootloader) to boot them. That works for me. However, I understand that the OP and others may have other needs. I only use my Win installation, which is crippled (no Network access), for gaming.
