How to change disk partition?

Question

linux

Hello, I decided to install Windows on the second hard, but I once used it to work with arch linux. Please tell me how to fix this error through the Archika console?

Windows cannot be installed to this drive. The selected disk contains an MBR partition table. On EFI Windows systems, you can only mount a GPT disk.

Answer 1

Windows cannot be installed to this drive. The selected disk contains an MBR partition table. On EFI Windows systems, you can only mount a GPT disk.

It is strange that Windows itself cannot change the partition table from mbr to gpt during installation (naturally , all data from the disk will be lost ).

sudo umount -R /dev/sdc
echo -e "label:gpt\nstart=2M" | sudo sfdisk /dev/sdc

where instead of sdc put the name of the desired disk (look through lsblk )

Answer 2

The first thing that Google gives out on request is "Linux GPT"
For Windows, accordingly, you need to format it not in Ext4, but in NTFS, and there is no need to mount it. Actually, you can format it using Windows tools.

Answer 3

Change boot type from UEFI to Legacy in BIOS.
Be careful, Archik may not boot.
And yes, Windows will overwrite the GRUB bootloader and you will have to restore it.
