So, finally got it solved. The aim of the question was that I couldn't install from the Live-USB, because it restarted over and over again. The problem was the partition of the HD (in Ubuntu terms, the sda device). It had 4 partitions, as @Sand-Dust mentioned, and all 4 of them were primary, with only one of these partitions empty, so there was nowhere to install Ubuntu (since from what I learned, it needs at least 2 partitions to install). The solution then was to ¿un-allocate? the partition sda4 (D:) and create 3 partitions in this now empty free space, all of this partitions being logical. You can do this with the installer, under the 'Something Else' option.
So after this, I've got Ubuntu intalled, but when restarting, it didn't show me the OS options, and started Windows... instead of messing with the GRUB, or Boot Repair, I chose to re-install Ubuntu, and now I'm writing from it.
Thanks for the comments and help.
I have done some reading & research but I`m rather confused about the whole issue of partitionning ie can I do that if I already have the following partitions:
Boot: 75GB used 47.5GB free (system NTFS) Recover: 7.20GB used 19.20GB free (system FAT32)
Yes that is possible.
Also I don`t quite understand LIVE CDs beyond that they are the operating system equivalent of perfume testers.
A LiveCD (or a LiveDVD) is a CD (or DVD) that you can use to try out the operating system without installing, or install it. So, yes, it's basicly both a perfume tester and the perfume itself in one.
I got some CDs from recent magazines I bought (UBuntu 13.04 and 12.10 - both 32bit), can I use these as LIVE CDs? If so how do I do that? Do I need to press a key when rebooting?
Yes. Put the disc of 13.04 in your PC, turn your PC off, and turn it on again. Wait a moment and a menu should appear that asks if you want to try Ubuntu without installing, or install it.
If not (and Windows Vista appears again), you should restart your PC again, and wait until the screen appears with Press <some button> to access boot menu. Then quickly press that key, and in the menu that appears, choose CD-ROM using the arrow keys and Enter.
Before installing, MAKE A BACKUP FIRST! Most installations will go flawlessly, but, like with everything, there's always the possibility of things going wrong.
The installation is pretty self-explanatory.
About partitioning:
The partitioning is really easy.
During installation, you can choose to install alongside Windows or install instead of Windows (WARNING: THE LATTER WILL DELETE ALL YOUR FILES STORED IN WINDOWS!!!). If you install alongside Windows, something like this will appear:
Just slide the line between Windows and Ubuntu to choose how many GB's you want to reserve for Windows and for Ubuntu. Then click "Install Now".
If you have any more questions, feel free to ask them!

It's a problem in the
/syslinux/txt.cfgof the bootkey.Where it says
/casper/vmlinuz, this has to be/casper/vmlinux.efi. Rename it, then you should be set.
