Windows 10 clean install

LOL, Ok Mr. never did any of it before, there on his laptop he bought and upgraded.

If you are telling me if you prepare a drive prior to install, that is it automatically over ridden, repartitioned and formatted you are full of it. This goes for MBR or GPT installs.

There is actually different partition sizes you can create.

So f...ing hilarious.

DERP, DERP, GIGGDY, GIGGIDY!

So in addition to not being able to write so that you can be understood, you also can't read and understand.

It is not so black and white. I think you are misunderstanding my comments.

you say>>but your contention that an EFI partition must be created by the user prior to a clean GPT installation is just wrong and makes no sense whatsoever.

If he want to do clean install using EFI, then you would want to partition the drive correctly, format and install. How does that not make sense.

Anyways, I am done. basic common sense.

Maybe I should rephrase. >>'PREPARE THE DRIVE"<<

If I'm misunderstanding your comments, it's because I'm reading what you wrote, not what you might have intended to write.   Write clearly and it won't be an issue.

Again, if you're doing a clean EFI install, there is no need to partition the drive before beginning the install.  You can do it during the install, and *there is no need to create an EFI partition beforehand.*Of course, if you want more than one partition (not including EFI or recovery), then those partitions could be prepared in advance.  But even if you do create an EFI partition beforehand, it will be overwritten during the install process *if the install is done correctly.*That's why I said it makes no sense.  If you have, in your own experience, wasted time in creating an EFI partition before the install, then when the install was complete noted the presence of the partition and assumed it to be the one you created, well...

It is not so black and white. I think you are misunderstanding my comments. I also know that things do not always pan out properly. There is also different situations.

Then he had 7 to 10 in BIOS and wants to convert to EFI. It does not always work so easily and then if a mistake is made after the partition is created and you then format NTFS, then the GPT is destroyed. So you get failed install, like I have seen 10,000 posts online and have to create partitions and start over.

Once YOU ACTUALLY WORK ON SOME PC'S, you will get what I am saying.

And I would SCRAP the EFI GPT and stay with BIOS MBR. Haven't seen any PC's failing on installs and upgrades or major updates with BIOS I have worked on, they are all failing with EFI.

The only BIOS failures were because of people doing stupid stuff and corrupting their OS.

Then was this an original OEM install. He wants to do a clean install. So is there software on an OEM partition. There are factors that are in play here.

LOL, no he was referring to switching to GPT BEFORE A CLEAN INSTALL. And if you are doing a clean install the first time using GPT EFI, the drive has to be prepared manually or using windows disk part, which is not always successful.

I am not going to debate, as I have did hundreds of installs. You put in a new HDD or switch from BIOS to EFI and try just to install windows using EFI and good luck. You have to prepare the drive first manually or using windows disk part. It is not rocket science.

I provided a link earlier to Microsoft's own instructions, but for convenience I'll provide it again (here) and show the relevant bit:

The drive won't be formatted GPT and put into EFI mode without an EFI partition being created during the installation process.  It is possible to manually convert NTFS to GPT, but your contention that an EFI partition must be created by the user prior to a clean GPT installation is just wrong and makes no sense whatsoever.
