Hi all, this is the first time I'll be doing this so bare with me for my limited knowledge.
I am looking for a way to convert my drive from MBR to GPT safely which will be my first time trying to do. I need to do this because I want to have both Windows 10 and a Linux Distribution to dual boot. I currently have a single MBR drive on my laptop on Windows 10 from where I am booting from (I only have 1 1TB drive on my laptop). I have been trying to install the Linux distribution via BIOS mode to the MBR drive for a couple of hours but it does not work (made a bootable USB via rufus program, set it to FAT32 and yes, - I didn't just copy/paste the ISO file onto the USB ), it keeps booting back to Windows 10 after I clicked on "install" when I reached the screen to install the OS, which leads me to the conclusion that I could only install it via UEFI mode (unless I have done something wrong or I missed a step). UEFI however, has to boot from a GPT drive for it to work which then leads me the need of converting my single MBR drive of my laptop to GPT.
The Linux distribution apparently can only be installed in UEFI mode and there are some issues of trying to make UEFI work with MBR drives: https://www.rodsbooks.com/gdisk/bios.html Essentially if i could have both operating systems installed on the converted GPT drive, I would be able to dual boot either of them without any issues via UEFI mode setting.
There are some articles in the net saying you can convert MBR to GPT drives straight away without any data loss by running some commands on disk part or using a software to do it for you without any precautions listed.
However, I have also read some precautions like you should not convert your boot drive from MBR to GPT which is why I am not sure how to go about this way or do not convert your MBR to GPT drive if it has partitions (which I do). The other option for me is to just format the drive as GPT and reinstall Windows 10.
So how should I convert my MBR to GPT drive safely?
