Windows 10: Is there a way to make 1 windows 10 drive that can boot uefi and legacy?

Right now I have 2 separate windows 10 drives. 1 boots uefi the other legacy. So was wondering if I can somehow make 1 drive with both capabilities.

UEFI vs Legacy boot mode

Yep, UEFI mode with Win 10 loading I get the Asus logo.

IIRC there maybe an option within motherboard UEFI to disable the Asus logo but not looked into it. On another forum I have read that what logo you get at Win 10 loading is the easiest way to know what bios mode OS is in.

If system is booting in legacy mode - you get Windows Logo.
If system is booting in UEFI mode - you get OEM logo.

Above also applies to Win 8 but not Win 7.

 

Trouble installing windows 7 on RAID in UEFI

As the title says, I'm trying to install Windows on a RAID array in uefi on my Maximus V Formula. When using legacy ROM I can install just fine but I go into CSM and change settings to UEFI only, I can build the array in the UEFI Raid driver (IRST tab in "BIOS") but the array does not show up in the boot menu and when I try to install windows (boot from UEFI DVD drive), The drive does not show up in the Windows install. The next thing I tried was to enable UEFI and legacy oprom in CSM, boot from UEFI DVD drive and install to the RAID array (probably detected by legacy oprom) and it will install. After first reboot, Windows Boot manager will show up as an option in the BIOS boot menu so I set that as first boot device and reboot. I will get to the starting windows screen and then BSOD (too quick to get codes) The last thing I tried was Changing to legacy mode and installing windows to a different drive. once installed, I initialized the Raid array as GPT and rebooted, changed csm back to UEFI only but they RAID array still doesn't show in the boot device list so I repeated the earlier process hoping that It might work because I had initialized as GPT but it still BSODs on starting windows screen. Any help or suggestions would be greatly appreciated

 

Notebook boots in Legacy not UEFI

Hi HannanShaikh,

You can convert your Legacy mode drive to UEFI boot anytime, visit this link:
Windows Setup: Installing using the MBR or GPT partition style for a comprehensive guide to reformat your hard disk to boot it to a UEFI mode.

The option to "Boot the PC to the DVD or USB key in UEFI mode" is also provided there.

Make sure that you use the same USB drive which already matched the edition of Windows 10 for your computer.

If you continue to have this issue even after performing the above steps, please reply to this thread. The system will notify me so I can get back to you and provide you more answers.
