MicroOS with MBR

[ksj6]

Hi,

I would like to install MicroOS as system to my server.
But I have issue - my old notebook, which I’m using as server, doesn’t support GPT. (It also always shows itself as with UEFI support, but there is no settings of UEFI in BIOS). So, I have to install it with MBR (I know it will not boot up with GPT). I checked the default layout of disks in installation MicroOS and I know I will have to probably set it manually in expert configuration the same way, but for MBR.

But in expert configuration I cannot see bios boot partition, which is used in default configuration layout.

I know there is some conversion tools, which can just convert partition table between GPT and MBR, but I’m not sure If it will not break up the system.

Can you help me, how to install the system?

GPT is supported by Linux, not hw.
Upgrade BIOS and try again.

It is an old notebook. There are no new BIOS upgrade.
I just know, I have to boot system from MBR disk. External disks I have in GPT.

MicroOS doesn’t support MBR partitioning, or BIOS Booting, as far as I know.

[ksj6]

In installation, in disk partitioning, in expert partitioning, there is possible to create MBR/GPT partition table. So, it supports it. And I can boot iso in gnome boxes with BIOS configuration, not UEFI.

Misunderstanding?

@sfalken

MicroOS doesn’t support MBR partitioning, or BIOS Booting, as far as I know.

I guess this is true for the boot/root disk/partition and as such explained.

@ksj6

in disk partitioning, in expert partitioning, there is possible to create MBR/GPT partition table.

This is about a partitioning tool that is able to edit/create MBR partitioned disks.

So you can still use MBR partitioned disks on the system, but not as disk to boot from.

So, there isn’t another way? I would like to have immutable system on server and other linux distributions, I tested are dependent on GPT.

I’m thinking of e.g. make gpt look like mbr with gdisk or recreate boot sector legacy way after installation on gpt disk (with --target=i386-pc) but I never tried it, if it will break something.

Try to search.

GPT+BIOS on openSUSE 13.1 x64

What is the best way to set up a GPT disk with a traditional BIOS on openSUSE 13.1 x64? I Googled it and found that a protective MBR is one answer, or creating a separate small boot partition to put Grub2 on. I see very little info on GPT+BIOS, and almost none pertaining to openSUSE. In the YaST setup phase, I don’t see anything that lets you set a partition on a disk to GPT besides a toggle option in the last screen to create a MBR or not on one partition. Is there an option hiding somewhere? I…

@ksj6

I have to boot system from MBR disk.

No, Linux can use GPT + legacy BIOS boot.

[ksj6]

You are right, I was afraid too much. it just works without any workarounds, possible gpt with legacy bios boot
