GeneralConverting boot from legacy to UEFI Pin

There is a much better and more detailed description of the conversion to UEFI process here: I suggest you read:

Preparing a Drive for UEFI Boot[^]

About a month ago my desktop started to develop speed wobbles. I got repeated blue screens, computer freezes and spontaneous restarts. Thinking it may be a virus, I ran tests and found nothing, so I thought it may be faulty memory, but memory diagnostics revealed nothing. Other hardware diagnostics from Dell revealed nothing. I replaced the system drive and re-installed Windows on a clean partition. It made no difference and I got fed up with the machine. It was time to replace it anyway, so I ordered a new Dell XPS desktop.

The new machine had DDR4 memory and a 3.4GHz processor that can spike up to 4GHz. It is lightning fast, but Dell supplied it with a clunky 7200 RPM drive that slowed it down. So I took the Samsung SSD from my old machine and replaced the systems drive. Of course, the new machine is capable of booting UEFI. At first I installed Windows 10 for legacy boot, but it bothered me that I was not using UEFI, so I decided to redo the installation. I have never done a UEFI install and was in for a rude awakening! It took me the better part of a day, just to get the partitions right and convince BIOS to boot from the new UEFI partition. I suffered several misfires and restarts of the disk preparation, before I got it right.

If you do not boot UEFI at the moment and are interested, I seriously advise you to be prepared to recover your existing setup if you fail with the UEFI option: Create a system image of your existing setup and a repair disc from which you can boot and install the image if you decide to give up.

Make sure your BIOS is not already booting UEFI, and if you are interested in proceeding, you will need the following to prepare a UEFI setup:

The tiny Windows PE operating system installed on a bootable CD or USB drive. It is barely 300MB in size, so it fits comfortably on a CD. You will need the DISKPART tool of Win PE to proceed. Note: There is a free third party tool, called Rufus, that you can use, but I decided to stick with Microsoft tools. To get Win PE, download and run the Windows ADK from here:

https://www.microsoft.com/en-us/download/details.aspx?id=30652[^]

Run it and create bootable Win PE media.

Prepare a bootable UEFI flash drive, about 5GB or more, and copy all the files and folders from your Windows 10 installation disc to the flash drive. You will need DISKPART to create the flash. You can read more about the use of DISKPART here:

https://technet.microsoft.com/en-us/library/cc766118(v=ws.10).aspx[^]

and here:

https://technet.microsoft.com/en-us/library/cc766465(v=ws.10).aspx[^]

First you clean all partitions from the flash drive, selecting it in DISKPART and then running the "clean" command on it. Be very afraid if you run this command on the wrong drive. DISKPART has no mercy and no "Are you sure?" prompts! Then convert the flash to MBR. Create a single bootable systems partition on it and copy all Windows install files to it.

You now need to clean your C:\ drive in a similar manner and create four partitions on it to very exact specifications. Details of the partitions are here:

https://technet.microsoft.com/en-us/library/hh824839.aspx#RecommendedPartitionConfigurations[^]

Sample scripts to automate the partition creation process are here: (I strongly advise you to use a script rather than entering commands one at a time by hand.)

https://technet.microsoft.com/en-us/library/hh825686.aspx[^]

Lastly: I cannot give you a detailed step by step process here. Read up on the process and follow other links in the webpages above. It is not a trivial process. Once you are ready to install Windows 10 on the UEFI partitions, remember to set your BIOS to boot in UEFI mode.
How do we preserve the wisdom men will need,
when their violent passions are spent?
