[REFERENCE: OS & Software > Windows OS > THREAD - "Xp will not boot without CD in drive " > Post # 17 (raybay endorsing Zenosincks suggestion in Post # 16 to Stobe's Post # 15)] I am on WinXP Home. For the last two days upon booting I get the message "Verifying DMI Pool Data ...../ Boot from CD: Failure ......../ Remove disks or other media./ Press any key to restart." This wasn't the case earlier. Obviously, tbe Boot process is detecting a CD or Floppy in the removable drive (a GHOST CD or Floppy). Perhaps some virus/malware has altered the Registry, for the BIOS boot sequence in Setup (1st Boot: CD, 2nd HDD, 3rd CD) is the same as before. It is not a terribly discommoding problem, as I have to just press any key to get on with booting. But the questions are: Why all of a sudden this new "protocol"? What is the solution? So will other affected/knowledgeable members contribute/enlighten me and may be kindred suffers on this problem? And, please, do not recommend changing the BIOS boot sequence entries in Setup.
