I want to install CentOS Stream on an older server. the Areca ARC-1680 RAID Controller is not supported anymore, so I tried to install on an external USB drive.

i did a manual partitioning:
sdc1 /boot/efi efi system partition sdc2 /boot ext4
sdc3 / lvm and the system cannot boot – hangs forever.

new try:
sdc1 /boot/efi, efi system partition sdc2 / xfs at end of install i see ‘bootloader install failed’. debug shows ‘NOTICE root:83haiku: debug: /dev/sdc1 is not a beFS partiotion: exiting’

then i did an automatic partitioning and got no efi partition. and the system cannot boot – hangs forever.

HOW do i install CentOS stream on external usb disk with efi boot?
