Hello Fanaudi,

Please go ahead and post back with a screenshot showing the full layout of your Disk Management window. This will let us know what your options may be.

Re: How to Convert a GPT Disk to a MBR Diske:

Brink ,
Thanks for the quick response .
Meanwhile , I have solved my compatibility issue ( error code 10 with a PCIe device ) . Nevertheless , if , for any other raison , I would choose to downgrade to Windows 7 , I would post you a screenshot of my Disk Management window . Btw , just formatting a GPT disc would set things strait , would'nt it or am I missing something here ? If this works , would I then need to reinstall a fresh version of Windows 7 or could I immediately boot a system image with my system repair disc ?
Thanks again for your attention .
Best regards ,
fanaudi .

Re : How to Convert a GPT Disk to a MBR Disk

Hello Brink ,
Just this small message to tell you that , like several other fellow users , I had enough of Windows 8 after 2 weeks on my desktop and decided to revert back to Windows 7 . The good news is that this was done without a single problem . Guess I was very lucky because , earlier after a full opgrade to Windows 8 , I noticed in the Disk Management that my System disc had remained MRB ( this is maybe normal only after an upgrade ? ) . All I needed to do was to insert my Windows 7 System Repair Disc , collect an Windows 7 image from my secundary and the job was done in less than half an hour .
Best regards ,
Chris .

hi,
thanks for the tutorial.
I tried to install Windows 7 on my laptop with pre-installed win8. as you can from my attachment, I failed to proceed through step "convert mbn".
Unfortunately I have already deleted and formated the partition with win8 so I cannot follow the guide you provided in the link above.
do you have any solution for me?
thanks in advance

I'm unable to boot up Windows 8 GPT disk. I made a bootable usb that allows me to open Mini Partition Wizard though. Can I convert a partition from GPT to MBR using this?
