No boots while starting Win Xp

Hello, I have a problem, see if you can help me:

When I started computer and I put the hard disks that had, believing that the boot would have no problem, but no. At the start I said that with windows start, and I got the message "there has been a problem when starting ...", it gives you the option of safely, how to network, with the last configuration that windows and functioned normally, I give either of them and it is as if they rebooted and then get to choose what the OS to begin with.

To see if you can help me, thanks.

a greeting.

If you have installed in each disk operating system uses a bootloader as GAG
If not boot the computer from the XP CD and use the console in the following commands:

fixmbr
fixboot
