Solved Windows 7 Installation Errors (0xc0000428)

[Kyyro]

So for quite a while I've really wanted to downgrade to Windows 7 from 10 as I find it much better. I bought my computer with Windows 10 64Bit already installed. However today I tried to downgrade to Windows 7 64Bit via usb and I received the following issues which frustrated me.

When I launch the installer, I choose the Custom option to clear all the files on my C drive and install a fresh copy of Windows 7. It installs for about 2 minutes then it says it has to restart my laptop so it does. After that it comes up with the boot manager https://gyazo.com/29ed207c0ed440adc83b73530f5e3db7 and has the two options of Windows 10 and Windows Setup. When I select Windows setup to continue with the installation of Windows 7 it pops up with this annoying screen. https://gyazo.com/139471fb8455893aa9d136525422cdb6

Any help please?

Win 7 can't be installed on some new laptops that came with win 10.
On the first picture it shows that you still have Win 10 boot manager.
- Did you created a factory recover set of DVD,s or USB so you can restore Win 10 even on a new HDD or SSD?
If you didn't erased the factory recover partition, you can still make it by BIOS option.

To install win 7, you must set OS=other on BIOS. If your BIOS doesn't have this option, or something like compatibility mode, you wont be able to install win 7.
Give us more info about your laptop, as brand and model.

My laptop is ASUS Model X555L. I don't think I made a factory recover. https://gyazo.com/06d1aed6c86d386b2ec969749fc5a5ea - List of my partitions.

I've had a look at your laptop manual - http://dlcdnet.asus.com/pub/ASUS/nb/X555LA/0409_E10576_X555LA_LD_LN_EM_V4_B.pdf
- In page 78 it shows how to how to make the recovery media. But it is inside Windows, probably using an image.

Can you still boot win 10?

 

[Kyyro]

I can still boot Win10 but I don't understand how to make the recovery media..

 

[Megahertz07]

That's good news. Did you see the manual page 78?

 

[Kyyro]

I did, it's just confusing. It only shows this https://gyazo.com/f9d8edc026516f9ef46818c0e6c0d0f6

Boot your computer on Win 10
Launch Settings and select Update and security.
Under the Update and security option, select Recovery then select the Advanced Startup. I cant help you further as I don't have your laptop in my hands.
Once you've created the recovery media, I'll give you instructions on how to try to install win 7

The W10 licence does not cover W7 installations, so you would have to buy one.

If you mean the product key, I already have a W7 one luckily.

Fair enough Kyyro,
As the bios is diiferent in w10, have a look at this tutorial.

Ok, I've created the recovery media on a disc using recdisc.

This is a risky operation as you're going do clean all the HDD, and as I wrote before, it may fail as Win 7 can't be installed on some new laptops that came with win 10. If you fail to install win 7, you have to boot from the recovery media you've created and restore to factory default (win 10), so it's important to be sure that the recovery media is working.

This is what I would do:
- Boot from the recovery media to see if it is working. You may have to enter your BIOS, and on Boot tab, set the disk priority to the media you created (DVD or USB)
- Reboot.
- Enter your BIOS and on Boot tab, disable Fast boot and enable Lunch CSM and save.
- Boot your Win 7 installation on UEFI mode, go to install, custom, advanced, delete all partitions, create a new one (Win will create 3 partitions) and proceed.
