I have got a problem that I have been trying to solve for about a week. On my ASUS X540SA (Originally Win10 installed),
RAM: 4096 MB; BIOS Vendor: American Megatrends; BIOS Version: 207; Processor: Intel(R) Celeron(R) CPU N3050 d 1.60GHz
I had Kali Linux installed. After some time I wanted Windows 7, so I downloaded an iso image and created a bootable USB drive. I popped it in and after the windows files loaded I got a BSOD. It said:
A problem has been detected and windows has been shut down to prevent damage to your computer.
If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:
Check to be sure you have adequate disk space. If a driver is identified in the Stop message, disable the driver or check with the manufacturer for driver updates. Try changing video adapters.
Check with your hardware vendor for any BIOS updates. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup options, and then select Safe Mode.
• Install FreeDOS and then tried to install Windows 7 again
So after I had installed FreeDOS and afterwards trying to install Windows 7, the windows files loaded and there was no BSOD, but the following message appeared:
Windows Boot Manager Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
Insert your Windows installation disc and restart your computer.
choose your language settings, and click "next"
Click "Repair your computer." If you do not have this disc, contact your system administrator or computer manufacturer for assistance.
Info: The selected entry could not be loaded because the application is missing or corrupt.
Afterwards I tried to install windows 10 because many users wrote that it is not possible to install windows 7. After I popped in the usb drive and booted from it, this popped up:
Your PC needs to be repaired
The operating system couldn't be loaded because the system registry file is missing or contains errors.
Downgrading from win10 to win7 is the worst idea you have had that day.
The error: STOP: 0x0000007e just showed a hardware issue with win7.
I question the reason for installing FreeDos, FreeDos is for playing classic DOS games, to run legacy business software, or to develop embedded systems.
To reinstall windows 10 from a usb instead of using the recovery image was another mistake
Seems that you succeeded in corrupting your registry.
You can try to factory reset, hoping you can access the recovery image.
Here is one way to factory reset an Asus laptop
Start your Netbook and press the F9 key on your keyboard until you see a loading screen.
The restoration program prepares the files needed for the operation.
A message appears asking if you want to perform the operation.
You will lose all files on your machine.
Confirm by clicking ?.
The restore process is done automatically, without any human intervention.
At the end of restoration, the machine will reboot on its own and make configurations.
A restart is performed again, and you find yourself on the setup process of Windows, same as the first boot after buying.
