Windows XP boot error and taskbar error

Hi. today I installed a brand new HDD so I can have a games drive.
Its working fine, formatted and up n running.

I restarted my computer earlier and now NTLDR is missing so it wont boot into windows automatically. But I can F12 into the boot menu and select my C drive and it boots into windows fine! Is there anyway I can sort this one out?

Also once in Windows, I cant click anywhere on my task bar, not even "start'.
Can anyone shed any light?

check hdd boot order in the bios. also are the hdds ide or sata.

edit: Problem solved, got out my windows disk, copied ntldr & ntdetect.com over to my C:\windows and the magic happened heheh. Thanks for you reply though
