I got an old PC (I think bought in 2002) just for some experiments. It has still windows XP Professional SP2 so I wanted at first install windows server 2008 (because I got it form DreamSpark) but that didn't work so I tried Xubuntu that didn't work because of a syslinux/isolinux error. Then I tried Ubuntu --> same error. Windows 7 USB didn't even boot. A XP recovery CD also didn't boot.
Then I did a BIOS reset and now it directly boots into windows xp it ignores the CDs and USBs also when I manualy choose them.
Can someone help me?
