I am interested in installing Xubuntu on an old HP running Windows XP (2003 Home Edition). The BIOS does not allow the alternative of booting from USB, nor do I have a CD/DVD-writer. I read in another thread that you can mount the iso-file (with Xubuntu) as a virtual disc of sorts (using e.g. VirtualClone I think it was), but my question is: is it possible to install Xubuntu from a virtual CD or do I need to either burn a CD/DVD or re-write the BIOS, allowing USB-booting?
All assistance is much appreciated, I am a beginner at this.
