I have recently set up my computer to be able to boot either XP or Vista. This machine, a Gateway DX420X dual core, came with XP Professional installed and a coupon for upgrading to Vista Business when it became available. I didn't load my Vista upgrade until recently when I decided to set up a dual-boot configuration. The setup went well and after re-partitioning my hard drive I loaded the Vista. When starting, I get the screen asking which system I want to use...XP or Vista. If I select Vista, everything works as it should. However, if I select XP, a screen comes up telling me that "Windows failed to start. To fix problem: 1. Insert your windows installation disc and restart your computer. 2. Choose your language settings and click /Next/. 3. Click /Repair your computer. /
This is followed by;
Info: The selected entry could not be loaded because the application is missing or corrupt.
I have tried numerous times to restart the computer using the *Windows XP Professional Operating System Disc* that was supplied with my machine in order to fix the problem. No joy! The system does not recognize the OS disc in the DVD drive and instead boots normally (again asking me which system I want to use).
How do I reload XP so that it is error free and still retain the dual-boot capability or am I committed to running only Vista?
