Windows 10: Move W10 MBR OS to GPT OS without re-installing windows

Hi folks

Following on from the previous thread in this section there is a way to move an MBR installation to a UEFI W10 installation without re-installing windows.

1) Get KYHI's recovery disk -- it's free and has all required programs on it as well as a load of other "goodies" on it.

2) Use rufus to create a bootable USB from the ISO -- you can use a DVD if you burned one but whoever uses those any more !!

2) restore as is your BIOS / MBR W10 installation to a non GPT disk on the target system.

3) boot the recovery disk (KYHI) --

Now follow the instructions on this link.

Hope this saves some people hassle and time.

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.

 

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.
