Hello, i am trying to setup a dual boot vista/xp system. I have a single drive partitioned into two active, primary partitions. Partition1 (C:\) has Visat 64bit installed and works fine, I can boot successfully to it. My question is how do i install XP on the second partition (D:\). When I do a system restart with the XP installation disc in the CDROM drive, immediately following the POST I get the error message NTLDR is missing, press ctrl+alt+del. I need to install XP (dual boot). Can anyone help?
