After this r -> g command, you still need to use w to write and quit. Until then, it seems nothing has happened yet (verify in another terminal with e.g. fdisk -l /dev/sdx ).

Aug 22, 2022 at 20:21 | comment | added | duct_tape_coder | This successfully converted my disk back to MBR but did not mark the Windows partition as Active and the disk was not bootable. I ended up using DISM to clone the Windows partition after doing a fresh install to restore the structure of the disk while preserving data. | |

Should I use gdisk when it is saying THIS OPERATION IS POTENTIALLY DESTRUCTIVE! ?

Jan 22, 2020 at 20:41 | comment | added | Will Matheson | "Converting" MBR to GPT this way (from a terminal in GParted or some other live distro) is good enough to get Windows 10 to install in UEFI mode, so even if it's not 100% right it's just what I need. (I care about keeping data because I dumped the disk structure from an old machine using Clonezilla and then am putting the new Win 10 in unallocated space.) | |
Oct 18, 2019 at 14:17 | comment | added | ManSamVampire | I observed this behaviour with gdisk v1.0.3 and fdisk from util-linux 2.33.1 when I was trying to convert an empty GPT disk (no partitions) to MBR | |

Something's not right. In gdisk recovery and transformation options the g option will only recreate the protective MBR on top of the GPT but not actually convert the disk to GPT. The right way to convert a GPT disk to MBR is using fdisk o option but it does destroy data on the disk.
