Installation of MX Linux on GPT disk failed - EFI wasn't selected?
by LinWinux from LinuxQuestions.org on (#6H2C1)
Back again, hello everyone.
After I added a GPT partition to my new 4TB Samsung Evo I went ahead and tried to prepare it properly in order to be able to install MX Linux 21.3 on it. For the installation I utilize a Live MX USB stick. This is something that I've done for years, probably installed MX Linux over 100 times on many different machines, but always on disks with MBR on them.
According to documentation that I located Online I created a 512 MB FAT32 boot partition as SDA1 and utilized the flag option to mark that partition as the boot partition.
Aside from a swap partition there is only one other 225GB partition which was created and formatted as ext4 in order to be able to install the system with root privileges.
The installation process began initially without a problem, except for the fact that a message appeared informing me of the missing MBR for which GRUB would be required. Proceed anyway? To which I responded, yes. I proceeded anyway because I had created the required EFI / FAT32 boot partition and figured that the MX installer would make use of that automatically. Sadly that wasn't the case. Upon rebooting the system an error appeared, boot disk or operating system couldn't be found.
So I figured perhaps it had something to do with my Bios settings. I made adjustments for disable legacy mode but keep secureboot enabled ... which did not work. Same message about missing boot disk or missing operating system. So I got back into the bios and changed the setting to enable legacy but keep secureboot disabled. Tried booting into the system again, same problem. My bios has the 4TB disk showing accurately (actually 3.73 TB). It is also selected to be the first boot device by default. So at this point I don't have a clue as to what I need to do in order to be able to boot my newly installed system?
Any helpful thoughts would be appreciated.
