How to convert boot disk to GPT format?

[tarazed]

About to take my first steps into the UEFI world having read a bit about it and have a series of questions.
gdisk is available in Mageia 4 but it is my understanding that the conversion of the boot disk has to be done externally, from a live disk for instance. So the question is, is there a live disk available which contains gdisk or one of the other GPT partitioning tools?

The system to be converted has three hard disks with single partitions on each for /, /home and /data. At this stage I am assuming that the home and data disks do not need to be modified.
The forums have threads concerning GPT partitioning but as far as I can see all the queries relate to issues beyond the initial type conversion.

Have downloaded the mga4.1 KDE Live DVD iso; shall check it out in due course.

There are numerous guides available, did you check them?

Yes, thanks, I found one or two guides like those. Once I have prepared a live medium I shall have a go at the conversion and document it here. An EFI bootable system would be useful platform for iso testing.

An EFI bootable system would be useful platform for iso testing.

FWIW, you can also do that in virtualbox.

Once booted into a live ISO you can add medias and install software in the live environment.
