Hi, I have a HP Compaq 6720s, BIOS version f.08, I already have installed Parrot OS Linux, but I wanted to dual boot it with Windows XP. After making a bootable USB with Windows XP, booting my laptop and selecting selecting to boot from USB, the screen shows something like "Intializing and establishing link.../Media check test failed", and after that, a black screen with a text "Non-system disk or disk error, replace and strike any key when ready". What should I do? If I try to install Linux from USB, it works, but if I try Windows(I tried also Windows 7, Windows 2000, Windows 8.1) it fails.
Thanks in advance
