Hi everyone,
I ve some problem, last days i bougth ssd drive to speed up a little my notebook. And there start problems. I can install all os only in MBR (firmware/Legacy bios Mode) but want to go on GPT. Was tryin everything. Was create hp_tools partition, install there firmware, update bios from 0.5 to 0.13f but still dont have option to switch from Legacy to uefi Mode on. As i have windows 10 (mainly was 7 starter but have w10 licence) i used MBR2gpt Mode all was perfect until restart cause have message that have to switch Legacy to uefi Mode, otherwise it wont boot up system. I dont want to install again MBR Type.. Please help

As long as there is no option to select UEFI in your "BIOS-Interface" you will not be able to run a GPT-Drive.
You should have checked that before you executed the MBR2GPT.exe.
What is the sense of an UEFI in that old 32-Bit machine?
You could try to go back to MBR in an PE-Environment or by 3rd-party partition tools.

There are actually two different aspects of GPT formatting -- BOOTING and USING.
To boot from a GPT-formatted drive, as indicates, your PC must support native UEFI boot capability. You can not do this if your PC only supports BIOS/MBR.
But, to use UEFI, you can so that using a BIOS booting PC -- I know this because I have older BIOS PCs that have data drives that are formatted GPT and work just fine.
