0x80070241 install Windows 7 to computer with Windows 8 preinstalled.

I have an Asus M11BB computer that is 5 months old that came with Windows 8 pre-installed. However, I would like to install Windows 7 on this computer as a Dual Boot, and I have the ISO burnt to a USB Stick. I can run the setup program both on startup by booting from the USB or while Windows 8 is already running. Both return the 0x80070241 error at 63% of copying Windows files.

BEFORE I start asking for help, is it possible to use the activation key from the bottom of my laptop on this install? I tried with a Virtual Machine and it works fine? If not, just leave it there as I'm not buying a new copy of Windows 7 just for this.

Presuming the answer was yes, I have split the D:\ partition (The C:\ contains the OS, the D:\ was blank on purchase) into a new B:\ partiton that is 100GB. When installing to the partition I get a message saying "Not in recommended order, for more info about installing to GPT disks please go to Microsoft.com". That is when I don't get an error saying it can't install to a GPT partition. I have reformatted that partition a number of times using both the Disk Management tool and the EaseUS program, no luck. So if I click OK, it goes to the copying Windows files and then throws up 0x80070241. That's the furthest I've got so far.

YES & NO, down to your UEFI/BIOS firmware setting.

1) Downgrade to Windows 7.
Downgrade Windows 8 to Windows 7
Warning you must have the UEFI/BIOS firmware setting in Step Three set.

Make sure you read the NOTE at Step three.

2) If Using a USB Pen drive on a PC with a UEFI BIOS.
USB Pen drive need to be formatted to FAT32 as in
UEFI Bootable USB Flash Drive - Create in Windows
Take note of Step 11 for Windows 7.
Also you will need to use a USB 2.0 port, as there are no USB 3.0 drivers in Windows 7.


You will need to buy Windows 7.

Oh, er, right. That's a problem.

The method detailed in the second post describes a complete downgrade. I don't want to do that, I need both for the time being.

OEM Licenses are tied to the computer on which they shipped.

So how do you explain the Virtual PC working then? The laptop containing Windows 7 is a Toshiba C660 Satellite bought from Argos in 2010, if that's any help.

EDIT: Booted up Virtual PC, "Copy of Windows not genuine." and a message "You may be a victim of software counterfeiting, to get updates and all that please validate it". So presumably doesn't work then?

I have always been able to adjust BIOS settings for Legacy, CSM and turn off Secure Boot in order to Dual Boot Win7/8 with 7 installed to UEFI to space shrunk from C.

Some BIOS however will not boot 8 without Secure Boot.

So, for the benefit of other users, how exactly do you install Windows 7? Secure Boot is off, and Fast Startup off as well.

The methods detailed require deletion of data on the hard disk, which neither I nor most other users would be prepared to do.

Ok, that's really as far as I can go now, as I have no intentions of buying another Win7 license at this point until I have a bit more money, so an installation is a bit pointless at the moment. I just wanted the info there really for others to refer too :)

Thanks for the help everyone though :)
