Windows 10: Convert Mid-2011 iMac from UEFI to Legacy BIOS.

Hello!

I have a mid-2011 iMac with which I am dual booting windows 10 and macOS high sierra. Since it is not compatible with bootcamp, I made a bootable usb drive and used that instead. This all worked very well except for that Windows does not recognize my sound card. I have tried to fix this for hours and hours, but eventually read that the iMac must be in legacy BIOS for this to work. Looking at some answers on the internet, every way to change the computer from UEFI to Legacy BIOS I found has confused me and would risk my hard drive getting wiped.


I would greatly appreciate it if someone had a relatively simple way to do this and could lay it out very clearly for me as I am not that knowledgeable with how all of these boot systems work.


I cannot put my Mac partition at risk but am willing to delete my Windows one and install Windows again if necessary.


Thank you so much for helping!


P.S. I am not sure whether I should have posted this on the Apple or Microsoft forums but hopefully this will work.

BSOD on mid-2011 imac running Windows.

After installing Windows on a mid-2011 imac using a USB boot drive (the imac is too old for Bootcamp), I get a system_thread_exception_not_handled error with a BSOD.

I can try to provide more information if needed but I am not sure what is relevant.

Thank you so much for your help.

 

Is there a way to convert my existing installed Windows 10 Legacy bios to UEFI?

Hi guys, is there a way to convert my OS's Legacy BIOS to UEFI? Reason for this absurdity is I want to dual boot Ubuntu 15 and whenever I disable the EFI setting in my BIOS my usb installer is not detected (obviously). I've searched about it and it leads
me to this article Converting Windows BIOS installation to UEFI - TechNet Articles - United States (English) - TechNet Wiki I just want to know if there are other steps before I follow the article. Thanks in advance.

I wanted to use a VM but my rig can't handle such.

 

Problem Regarding Bios Change from UEFI to Legacy

I have hp pavilion p045tx with windows 10 pro. I recently install Ubuntu with windows 10 so for that I convert my bios setting from UEFI to Legacy mode for install third party software like wireless Driver and all in Ubuntu.
But after every restart the bios setting change to default and that is to UEFI mode and that will cause an problem of no OS detect. Every time I have to go to bios setting and enable the legacy mode to start my OS. Can anyone suggest me what to do in this
case.
