Ok, This was apparently not meant to be and someone was REALLY watching out for me big time.
Windows will not allow you to downgrade to an operating system earlier than the current one. . .this means you have to wipe the current OS clean and start over from scratch. The suggested utility for this is DBan which normally does a very thorough job of wiping the disk clean for a new OS. I downloaded the program, burned a CD to boot from and I had already copied or backed up everything I could think of that I wanted to save.
All is ready, I restart the computer, set the BIOS to accept the CD as the bootable drive, reboot and start the DBAN program, click the appropriate selection for my needs and the "wipe" process begins. Almost immediately it stops with a message that it was finished with "NON-FATAL ERRORS". . .oh great, it couldn't just be finished, it had to be finished with errors? Just what I needed.
At any rate I restart the computer, this time with the XP Installation disk inserted. The process starts, it tells me that there is no windows OS Installed and asked me what I wanted to do, I select to install Windows XP. It starts installing the necessary files for startup and installation. . . .done with all that, I click continue and then it says that I need to insert. . . .The Windows XP Installation Disk. . . .huh? I open the CD door, close it again (maybe it didn't realize it was there all the time, lol), I get the same message. . . .I check the CD, yep it says Windows XP Home Edition. . . .so what gives? I try several more times, but it ain't budging, it wants that disk and it wants it now or it ain't gonna do nuthin'. . . .so I look one more time at the disk and up in the left hand corner there, in smnaller letters it says "upgrade".
Two things saved me here. . .one, the DBan utility, for whatever reason, did not run despite what it said and. . .two, I didn't somehow screw up the current OS to the point that it wouldn't reboot. So, lesson learned. . . .if it ain't really, really, really broke. . . .don't try to fix it and a little side note, Windows XP Home Edition "upgrade" is not considered a full version.
I'll be sticking with Vista.
