I have a Toshiba Satellite L305D notebook that had Windows 7 on it.
I recently installed Ubuntu on a partition and uninstalled Windows erasing its partition and its "System reserved" one, leaving a large unallocated space at the beginning of the hard drive; then updated grub.
Now I'm trying to install Windows XP Pro SP3, with no luck.
With an ISO image downloaded from Microsoft website, I prepared a bootable USB that works in a Dell Windows 7 notebook but doesn't in my Toshiba! Same goes for bootable DVD. And it does boot other stuff such as Ubuntu installer and GParted Live, but not Win XP installer.
When I try to boot it, the screen goes black a second and then loads Ubuntu like normal startup. BIOS doen't have UEFI capability, so that isn't the problem. Also tried swiching SATA mode from AHCI to Compatibility mode, but did nothing. Not much interesting options in the BIOS settings. Any ideas?
