well i was thinking of installing windows again.. then i changed my mind but the thing is from my bios it wants to start up with the setup with installing the new windows. how do i stop this.?

What is the exact prompt?

Resetting the BIOS defaults or clearing the CMOS is one way.

Perhaps easier is to enter the BIOS Setup Boot tab and check the options that might be triggering this. Set your old hard drive as the primary hard drive device.

Once you get your XP working properly this might just go away as well.

ok my problem is:#

i choose to reinstall windows. On my Bios it allows me to choose what windows i want to go on to...i have a mixture of home and professional XPs..
it has a countdown if i was not to press enter anything and will go onto the defaulted Windows. but now there is also oone for Windows Xp set up.. i want to cancel this.. because this has a shorter countdown of 3 seconds and tends to be annoying since i do not want to reinstall windows again!

Find the partition that this Setup is on and delete it.

How do you find that Partition.
On Bios i tried to Press delete while it was highlighted yte nothing happens

I think after you get XP reinstalled this issue will vanish.

ok..re installation will never happen again...it will get stuck on the process of "Searching for Previous versions of windows".. i know it will..

Thank You Jephree!
