Install using MBR disk label

English Install/Boot/Login
1

I have a new computer that came with Windows 10, which uses UEFI with a disk that has a GPT label. I would like to erase Windows and install Leap 42.1 on it using Legacy Bios and a MBR disk label. The disk has 2 TB of space. I was able to switch to “Legacy only” in the boot setup and boot from the openSUSE CD. I selected “Expert Partitioner” in the installer. However, I did not see any option to change the disk label from GPT to MBR.

Is there any way during installation to change the disk label from GPT to MBR?

Does the Expert Partitioner in general default to creating a GPT label, for example on a new unformatted disk, even if not larger than 2 TB?

Install won’t do it I don’t think need to use an external program but GPT is the better choice since you are not limited by the need for extended partition. In fact IMHO EFI is the better choice for booting also on modern equipment .

But if you want this is a good way http://gparted.org/download.php

Changing the partition tables will make anything on the disk unusable

BTW 2 TB is the limit of DOS partitioning

In expert partitioner select disk in the object tree in the left frame. Then you should have small menu Expert in the lower right corner in the right frame which allows you to create new partition table.

? Why 42.1 and 42.2

You need to use legacy BIOS IIRC

I assume you mean MBR resp. GPT “table” andf not “label”. Else request question becomes puzzling.

Not really, “label” is commonly used in this context.

Hm, strange, but there are many more confusing terms used here.

In my opinion, it would be better to stay with UEFI and GPT. They are the future, and linux handles both quite well. Your 2T hard drive is near the limit for legacy partitioning.

However, the “gdisk” utility can be used to “zap” the GPT partition table. Even if you prefer legacy booting, linux still works well with GPT partitioning.

I guess you could download the Tumbleweed Rescue CD. While running that, get into Yast software management, and install “gdisk” (I think the package name is actually “gptfdisk”). Then run “gdisk” on your hard drive. Look for the extended menu in “gdisk” and the “z” command.
