Windows 10: Can't install windows 10, all drivers are MBR not GPT

I was trying to install Windows 10 from a USB flash driver I made with " creation media tool ".


At first I was trying to format the C drive but got an error after the C was already formated that it was MBR and GPT so windows cannot be installed.


Attempting to use the " mbr2gpt" commands didn't work. And the line before the commands was " x:sources >" instead of "x:windows/system32 " as it appeared with others.


How can I install windows again?

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

If I have UEFI BIOS, I'm going to use GPT. Only reason why I wouldn't is because the drive is shared between new and old computers (MBR has broader compatibility support). I wrote a guide how to install Windows on GPT here:
Installing Windows Vista/7 on a GUID Partition Table

No. Either you install on GPT via EFI boot or you intall MBR via BIOS boot. You can't install Windows and change it later.


Not only does GPT support booting to partitions larger than 2 TB, it also means the computer is booted using EFI which means it has a lot more memory to work with during startup. It should theoretically mean startup is quicker on EFI/GPT than BIOS/MBR.

So I cannot use all the new bios UI and fancy pre-boot evironiment if i don't use UEFI-boot ? With or without GPT?


I just want to use the UEFI without GPT: so can I UEFI-boot and install win7 with MBR?

Now I actually asked the correct question I wanted. Sorry it took time to figure out.

Sigh.

BIOS is being replaced with UEFI. Both BIOS and UEFI tell the hardware how to communicate, turn it on, and generally make your system start-up. As such, you could theoretically have a set of hardware that runs Linux, Windows 98, and Windows 8 while still getting UEFI support during the boot-up (assuming you've got a hardware CSM).

So yes, you can go MBR and get the UEFI visual boot-up options. The visual cues will be determined by your motherboard manufacturer. GPT is not a necessity, unless you are using a boot disk larger than 2TB.


In short, because every time it seems there's more information you raise a different question:
Yes, you can have UEFI on a Windows 7 install with MBR partitioning.
No, UEFI does not require GPT partitioning.
You should install windows 7 with the default settings (MBR) for compatibility and ease of install.
Yes, GPT will unlock some new features, but they are unlikely to benefit you.
