Windows 10: installing with UEFI/GPT - 1803 build

trying to install a UEFI/GPT setup, but keep getting "unauthorised changes on firmware/OS or UEFI drivers" message.

When i disable CSM/UEFI in BIOS it works but I cant seem to get the installer to create the extra three partitions for a proper install, only one.

GPT vs MBR for SSD OS Disk ? (win7 install)

So

I've got a new PC coming and this time it's the first time I will be using UEFI, i have read all the big stuff but I don't have the hardware yet so It's still kind of half baked but I'll do dig deep into it once I start building in the coming days.

I've read the win7 install guides, MS GPT FAQs (not fully yet), etc,

But I wish to know if:

I can use UEFI as an upgraded bios without having to use GPT disk format?

GPT disks can have any sort of partition cloning for full operational OS backup ?

Will GPT format improve performance on SDD or improve reliability in terms of data integrity or error rate?

When isntalling win7 with MBR but using UEFI, will it work normally without needing to uefi-boot the window7 install?


If I cannot backup my OS in a 100% clone that will boot normally when recovered, i will probably not use GPT, that shit is a step backward.

 

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.
