I have this same error message on my computer. I went to the
microsoft support to figure out how to fix it and i am having problems with step 3
1. Insert the Windows XP startup disk into the floppy disk drive, or insert the Windows XP CD-ROM into the CD-ROM drive, and then restart the computer.
Click to select any options that are required to start the computer from the CD-ROM drive if you are prompted to do so.
2. When the "Welcome to Setup" screen appears, press R to start the Recovery Console.
3. If you have a dual-boot or multiple-boot computer, select the installation that you want to access from the Recovery Console.
I get to the recovery console screen and it tells me to select the installation that I want to access. There is only one option so i press 1 and then press enter. after that it takes me to a blue screen that says i have a Bad_Pool_Caller. Please help me,
