  1. Unable to install Windows 20H1 and newer onto UEFI system.


    I switched my motherboard from BIOS mode to UEFI mode, and can no longer install newer version of windows. When inserting the bootable drive, it is unable to read it and just boot loops.The source of the problem is that for the bootable drive to work, it needs to be formatted as FAT32 for UEFI systems to read.However, using the Windows Media Creation Tool, there is no option to select which format to use.Using Rufus, I am able to select FAT32 for any Windows version BEFORE 20H1, but not 20H1 and newer.Any attempt at installing an older version of Windows and updating to a newer version via sys

    :)

  2. 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

    Trouble installing windows 7 on RAID in UEFI

    I think you were on track with your first try. Windows installer probably needs the RAID driver in order to detect it on install.
