I bought an
Asus K55 and wish to downgrade from windows 8 to windows 7 with a windows 7 Home Premium upgrade disk. I went through the installation process, but upon reboot, I get a screen telling me that a driver was corrupted, or something of that manner. Upon attempting to install it again, I notice that on the first screen of Operating System installation, after choosing a custom install, and choosing the partition to install to, I notice that after choosing the proper partition, I get an error saying that the disk order installation is incorrect for the GPT. It also gives me error code 0x8003002 which I have not been able to find any relevant to online.
On the error screen that comes up when the computer restarts in the middle of windows 7 installation says:
A recent hardware or software change might have installed a file that is signed incorrectly or damage, or that might be malicious software from an unknown source.
Of you have a windows installation disc, insert the disc and restart your computer. Click Repair your Computer," and then choose recovery tool.
Otherwise, to start windows so you can investigate further, press the ENTER key to display the boot menu, press F8 for Advanced Boot Options, and select Last Known Good. If you understand why the digital signature cannot be verified and want to start windows without this file, temporarily disable driver signature enforcement.
File: \$WINDOWS.~BT\Windows\system32\winload.efi
Status: 0xc0000428
Info: The digital signature for this file couldn't be verified.
That's all the information I have for this issue that I know to be relevant. If you can help me, I thank you very much.
