Cant boot from Windows 8 to Windows 7

by yobacan / December 18, 2012 12:48 AM PST

Hello,

I want to install W7 on my newly acquired notebook with W8. So, for that I download W7 and burned it from ISO to a DVD and put in the notebook. Now, I am not an expert, but still didnt want to spend money on pc technicians, so I was careful about looking for information on how to reboot (I selected UEFI configuration on advanced options). After going into BIOS, I set the order to 1st boot device CD/DVD, and 2nd boot device hard-drive, and put Secure boot to disabled option. So, when I restart windows and it asks to press a button I do it and then it shows me a long message, which says:

"Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:

1. Insert your Windows installation disc and restart your computer
2. Choose your language settings and then click "Next"
3. Click "Repair your computer"

If you do not have this disc, contact your system administrator or computer manufacturer for assitance.

File: \EFI\Microsoft\Boot\BCD
Status: 0xc000000d
Info: An error ocurred while attempting to read the boot configuration data.


I hope you can help me solve this because I have no idea to do, and as I said, I am not an expert. I dont know if the problem is the CD or the Windows itself.

Thanks!

Such a setup is not supported by Microsoft. Unless you find some hack on the web, you need to do this the supported (EXPENSIVE) way by installing 7 clean and maybe by setting to UEFI to legacy mode (BIOS) and then installing 7 clean. Then leave unpartitioned space to install your second license OEM Windows 8 Pro to .

The license of Windows 8 is forgotten and some folk get uppity about this.

You can install Windows 7 Pro or better in a virtual PC like "Virtual Box" if need be.

Bob, thanks for your answer, but since I am not an expert, I couldnt understand much of it. What I could sense was that it does not look easy, and maybe I will have to look for a technician in the end.

In reply to: re

To get this done the tech would need the full retail version of Windows 7 to install first. Then for Windows 8 you need the OEM Version of which version of 8 you want. The prior license is not usable for this endeavor.

The tech would then have to find drivers for each OS and would set up the dual boot.

-> Be sure to have them create a way to restore such a setup as reinstalling is not that easy. I suggest ACRONIS to backup the entire drive to some USB external since the number of DVDs is too unwieldy. You'll need the latest ACRONIS if you decide to leave this machine in it's UEFI glory.

One last issue. For now, today there is no free way to reset passwords on Windows installed under UEFI. This may change but as a safe guard please create spare admin capable accounts.

Not clear.

Do you want to install Windows 7 REPLACING Windows 8? That's easy with a Windows 7 disk, although you might need to use DBAN or KILLDISK first to fully erase the hard disk. But I fail to see why you didn't buy a notebook with Windows 7 then.
Be sure you can get all drivers for Windows 7. That might be an issue if it came with Windows 8.

Or do you want to make a dual-boot configuration, so you can choose which one to use when you boot? That's complex, as Bob writes.

If you are going to go this route it is a must to do it right not by some half baked idea or "hack". His way will give you the best results and the best dual booting system possible. I learned the hard way and although not cheap it really is the only way to go.
