go into the bios where the boot choices are and move the floppy drive behind the hard drive. when you reinstalled xp it defaulted to trying to read the floppy drive first.
After reinstalling XP on my Dimension E510, each time I turn on the machine I get a message that Drive 1 is not found; Serial ATA, SATA-2 ; floppy disk seek error. I then need to press F1 to continue. Then I'm brought to a screen asking me which OS I want to run. Both choices are XP Media Center.  The process is annoying and redundant & the DVD drive seems to work fine. What caused it and how do I fix it so it boots to Windows screen directly? Thx for any suggestions or help.
