Since the XP CD is copyable, why wouldn't everyone have a backup copy? CDs are about a nickel and DVDs are about 20 cents (around here.)
When I boot up it goes to Windows Boot Manger:
"Choose an operating system to start: Press tab to select a tool:
Windows 7
Microsoft Windows XP 64-bit Edition Version 2003 Setup. (This one is highlighted)
To specify an advanced option for this choice, press F8
Tools:
Windows memory diagnostic"
If I leave it and don't use the up arrow after so many seconds it goes to the XP Setup and the blue screen comes on with Windows Setup at the top (underlined twice) and at the bottom is "Setup is staring Windows" and then immediately BSOD with the message that "A problem has been detected and Windows has been shut down to prevent damage to your computer: . . . .
Technical Information:
"*** STOP: 0X0000007B (0XFFFFFADE63C323C0,0XFFFFFFFFC00000034,0X0000000000000000,0X0000000000000000)"
This all began when I tried to install Windows XP from what I now believe is a non-operable DVD (has a crack running from the spindle hole into the software area) and after Loading files it would get to: " Windows XP Professional Setup
Welcome to Setup.
This portion of the Setup program prepares Microsoft Windows to run on your computer.
To set up Windows now, press ENTER.
To repair a Windows installation using Recovery Console, Press R
To quit Setup without installing Windows, press F3"
At that point it would lock up, pressing enter or any of the other choices didn't do anything. So I turned off the computer and since then the above scenario takes place.
Previous to this when I would boot up, it would bypass Windows Boot Manager and go directly to Windows 7
Information from ASUS UEFI BIOS Utility - EZ Mode
BOOT PRIORITY
Use the mouse to drag or keyboard to navigate to decide the boot priority.
(Then below that are 3 icons or symbols the first of which looks like an upside down padlock and the other two are rectangles with a blue circle and white circle within that. The last rectangles has UEFI underneath)
When hovering the mouse over the icon this is what comes up
First Icon: SATA SM: ASUS DRW-24BIST (which is my CD/DVD Burner0
Second Icon: SATA PM: ST3000DM001-1CH166 (2861588MB) (This is my primary master where win 7 operating system is located.
Third Icon: Windows Boot Manger (SS: WDC WD1600YS-01SHB1 (This is an internal hard drive where Win 8 is located
I have switched the order so now the first Icon is the SATA PM, the second is the internal drive with Win8 and the third is the CD/DVD Burner. This has not changed anything as far as the boot up process - still goes to Windows Boot Manager.
Have used the restore function to go back before this problem began but it didn't change the Boot Manager problem

What I am hoping is that there is someway to get it back to where it was before the problems began or at least have Win 7 highlighted in Windows Boot Manager so that when I turn the computer on in the morning, I don't have to wait until the Boot manager comes up and the hit the up arrow and then enter. Any suggestions will be most welcome.
