To put it simply, WinXP Pro won't boot up. What happens is as follows: computer turns on, goes through the basic checks and starts the boot agent. As soon as the agent checks for any floppies or cds, it (i'm assuming it does, at least) attempts to start XP. At which point it outputs something like this: L 40 40 40 40 40 40 40 40 ...(with 40's continually being output) I have installed Debian, which works fine, and the last (big) thing I did before the problem came along was to delete my former linux swap partition and a larger (linux) partition using the XP Pro administration tools and turn them into one FAT32 logical drive, which I then moved a few things onto. It was all fine until I rebooted. I have one hard drive, so both of the (former) linux partitions were on the same drive that XP is on. Tell me if you need more info and thanks for any help that I get.
