This article introduces the relevant knowledge of "how to solve the problem of GPT partition table encountered when installing linux". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

First, if Windows, VMware, Mac OS have been installed on the server before, you may encounter the problem of "your boot partition uses GPT partition table, but this machine does not support booting with GPT" when installing linux.

Second, the reasons:

In order to solve the problem that MBR only supports hard drives below 2TB, Microsoft and Intel have developed GPT partition mode, which makes the manageable hard disk size up to 18EB. The partition information of GPT is in the partition, not in the main boot sector like MBR. In order to protect GPT from the harm of MBR class management software, GPT establishes a MBR partition table to protect the partition in the main boot sector. When installing linux, the MBR disk management software treats GPT as a partition of an unknown format, resulting in problems that cannot be installed properly.

Third, the solution:

1. Redo hard raid.

2. Write data to disk and overwrite GPT partition table:

Dd if=/dev/zero of=/dev/sda bs=1M count=1
