Windows 10: Clean install in UEFI mode

Hi

I am about to receive the bits to upgrade my husbands PC from a simple desktop machine to what the PC Gamer site assures me is a high end gaming machine. However, in the process I want to take the opportunity of also upgrading to a UEFI system from MBR but I'm a little confused on how to do it.

I've done a search of the internet and found what seems to be a confusing number of ways of doing this. I've got a bootable USB containing the source files which I understand is capable of installing to either UEFI or MBR. Now I think its just a case of simply installing to an unallocated but GPT initialised disk or is there something more involved like altering firmware settings? Somehow I converted a spare PC we have to UEFI without even trying and have no idea how it happened -- not that I'm complaining mind you, it just took me by surprise!

Anyway, any help anyone could give would be most appreciated. If any further info is needed then please let me know and I'll do my best to help.

Can Not Install W10 in UEFI Mode


Hi,

For as long as CSM is enabled Windows will install in legacy/bios mode. There is no such thing as a UEFI command really unless you're actually coding it.

Step 1: Enter bios and disable CSM

Step 2: Insert the install DVD

Step 3: save changes in bios and reset.

Step 4: toggle the key to invoke the bootmenu. (F8?) and select booting from dvd/bd whatever it is.

Windows setup should now launch. When arrived at the point to select a clean install select that and delete all partitions except you data partition(s) if any.
Windows will then continue to create all system partition for you. If it complains the partitions may not be in the preferred order, ignore it and continue.

Let it finish et voila, you now should have a UEFI installed system.

Cheers, *Wink

 

Clean Install Workaround for Vista

You may remember this news story on techPowerUp! a couple of days ago relating to the lack of clean installs when using the Upgrade Editions of Vista, which required an old OS to be installed. However, Paul Thurrott has managed to find a workaround for this issue, which ironically lets users do a clean install Vista without any previous version of Windows, albeit a little tedious. Here are the steps:

• Boot from the Windows Vista Upgrade DVD as normal
• When prompted for a product code, leave this blank
• Select the version of Vista you have purchased and let Vista install
• When you boot to your desktop for the first time, run the Vista setup from Windows
• This time enter your product key
• When asked whether you want to do an Upgrade of Custom install, select custom and choose a clean install
• Windows will now install for a second time and you should be able to activate it

Remember, these steps are only advised for use in order to achieve a clean install of Vista, it is only legal to use the upgrade editions if you have previously purchased the appropriate version of Windows.

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
