Windows 7: Vista not recognizing win 7 installation dvd

so, a super annoying issue. a newer hp desktop with vista installed had a sophisticated virus/malware which caused the network/internet to not work on it(completely messed up the dns settings and who knows what else) , and i cannot do a system restore, and it wont even recognize the bootable win 7 dvd. the win 7 dvd works on any other computer, but on this, it doesnt boot for it or even show up in "my computer",not even in safe mode or anything. any other dvd or cd, even the windows xp cd is recognized. i did the "disable driver signature enforcement" before windows vista boot, and still no luck. please help, i need to somehow get win 7 installed on this, as the virus/spyware messed up the dns/network adapters, and i think it'd be easier just to install win 7.

If you want to try to repair Vista follow these same steps for Troubleshooting Windows 7 Failure to Boot

If you're ready to install Windows 7 wipe the HD first using Diskpart Clean Command from the installer's Command Line accessed by DISKPART At PC Startup.


Try triggering the installer to boot by tapping the HP ESC key at boot. This is almost always a failure by the user to boot the installer or Repair CD correctly.


Failure to boot a disk is 90% of the time user error, reset the CMOS: Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS. Set HD to boot first in BIOS setup, use ESC key to boot installer or boot disks.

If this continues to fail, download and burn to DVD or write to flash stick the latest official Installer with the tool provided in Clean Reinstall - Factory OEM Windows 7 to see if the installer is the problem.

If not then download, burn to CD using Windows Image Burner then boot free Partition Wizard bootable CD or DBAN CD which will boot itself without user prompting, wipe the HD from Disk Tab after highlighting the HD #.

This will force the installer to also boot itself so you can follow the steps in Clean Reinstall to get a perfect Windows 7 install.
