convert existing arch disk from MBR to UEFI?
I have Arch and Win 10 on my current system (i9-9900k/Z370 board), each OS is on a separate nvme drive, each is MBR. Upgrading computer to R7-5800X3D/X570 board (MSI Mag x570 Tomahawk wifi). I know I can convert my Win 10 drive to GPT then clone it to the new PCIe 4 nvme, can I do the same for my existing Arch drive? New board has no legacy boot option.

Re: convert existing arch disk from MBR to UEFI?
Your description doesn't seem to match your title. Do you need to convert a single disk from MBR to UEFI, or are you migrating to new hardware with a new disk? If the latter, this is trivial. Just partition the new drive properly as GPT (including an appropriate efi partition), mount the partitions and copy everything over. You'll then just need to change / update your boot-loader/manager.

Re: convert existing arch disk from MBR to UEFI?
Just wanted to know if I can convert an existing Arch MBR drive to GPT? I had cloned the Arch drive to a larger nvme before I got the new board & CPU not knowing the new board had no legacy support in the BIOS.
Or should I just wipe the new nvme, use gparted to create a new GPT and use a timeshift backup to restore the data?
As a Arch novice user is there a guide in the wiki on updating/installing a new bootloader?

Re: convert existing arch disk from MBR to UEFI?
You should start with a freshly partitioned GPT disk.
There is tons of stuff in the Arch Wiki about installing and configuring a new bootloader. There are several equally valid ways to do it. I use systemd-boot, but you'll have to decide for yourself. Good luck!
