Good morning,

I installed Windows 8 on an old P4 and it worked. Then I install Ubuntu 14.04.1 LTS after having created a partition for it. Everything went right and I can access Ubuntu by choosing the option in GRUB. However, when I choose Windows 8, which is displayed, the screen goes black and the computer restart. This is an assembled machine, and the thing is that before the old P4 I used the very same HD with an i5 and UEFI system. Anyway, I formatted the HD as a msdos partition type, but I don't know if there could be still something wrong. I looked for a solution online, but I didn't find anything. I tried also Boot-Repair, without any results. You can find the output script here: http://paste.ubuntu.com/7955901/

Running fdisk -l, I have:

Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors

Partition table entries are not in disk order

and running cat /boot/grub/grub.cfg, I have
