AMD data change.......no boot up problem

[adayyum]

Hello all,
Thanks in advance to what you can offer for help. I have searched this forum for a similar problem and while I have found threads I cant really follow the instructions to fix the problem as I get lost in the posts and replies. Anyways my aunt's computer boots to this screen:

AMD Data Change...Update New Data to DMI!
NVIDIA Boot Agent 249.0542

CLIENT MAC ADDR: 00 26 2D 2C D7 A1 GUID: ACF513C0-CD7D-11D3-92F5-00262D2CD7A1
PXE-E53: No boot filename recieved

PXE-M0F: Exiting NVIDIA Boot Agent.
DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER

Computer is a ACER ASPIRE with win 7 64bit , Athlon 2 X2

I've put in the windows 7 cd and it seems to not read and I know the copy is good it seems to not try to read any disc put in. Reboots with disc in, power cord unplugged still same screen. Any help please. Also Im not that tech savvy so if you could hold my hand like a little child crossing the road that would be much appreciated. Thanks again for what you can offer.

Need to reinstall windows and/or disable network boot rom. In other words, it can't find a hard drive to boot from.

EDIT:

Check to see if you have a Bios boot menu you can utilize and try the cd from that.

My guess is that the CMOS is scrambled and needs to be reset or that the CMOS battery has died.

make sure you disable network boot and then make sure the HDD is the first boot device.

1st: go to bios, check boot device TYPE priority (cdrom/hdd/etc.)
then, go to hard disk drives (still under boot category), and check if your system hard drive is at 1st place (IF you have more than 1 hdd)
2nd: if your bios boot settings are OK, run windows 7 installation disc, go to repair your system, run fixmbr and fixboot options (i think they are at same option on windows 7 repair - startup repair or something like that)
3rd: if your windows 7 installation disc cannot find your windows 7 installation, reinstall it, but take care - you may have bad sectors on your hdd

please, go step by step, and dont read 3rd step warning before you try 1st and 2nd xD

you can also disable "LAN boot ROM" option under "integrated devices" bios category to never see that meesage again (at least 3 NVIDIA Boot Agent lines xD )
