Hello ,
I just setup PVE 6.2.1 on HP Z600 (not support UEFI), but before that , I tried PVE 6.4.1 , the installation got stuck at the 99% progress ,which is "Making system bootable" , I wait for that a long time, but it was still not competed, then I abort the installation.(I also can't find any error in debug mode -- cat /tmp/installation.log)
If I install PVE with v6.2.1, the installation was completed without problem, but I feel confused for bellow concerns:
1. when I reboot my host , the host keep show me "Booting from Hard Disk ..." for one-two minutes , then it boot into PVE, when it boot into OS , I check my hard disk from shell. I found PVE installation format my 12 hard disks with GPT. but my host is too old , it just support BIOS , not UEFI , how can it boot GPT hard disk ?
2. Later I learn that GPT scheme has a sector reserved for MBR (0 sector, first sector of disk) for compatibility. then I check the first sector on one of my hard disk with HxD tool. it's a 512Byte sized sector, the first 446 Bytes is for bootstrap code, the middle 46 Bytes is for partition table, and the last 2 Bytes is for MBR signature. GPT header begins at 2rd sector.
3. just like the attached screenshot, it just mentions a little information which I can understand (.>>.pev.i.s.z,o .. strange letters), so it can't make me understand how it work, I want to know how to translate the bootstrap code (first 446 Bytes) into human readable code. I want to know how PVE is boot on my Z600 , as it's disk is GPT format , and it doesn't support UEFI. I'm a little worried that it will fail to boot in the future.
