Can't use ISO to install CentOS 9

  • Hi,


    I'm having the same problem and just opened a ticket with Netcup support. In my case, it's one the ARM servers in Nuremberg - the error message is "Couldn't find UEFI Misc Device 2". I already tried the other available ISO (which is Ubuntu for ARM), changing the boot order, and even erased the hard disk image (because I thought, perhaps it's just the boot order not being saved, so if there's nothing bootable on the disk, it should use the DVD image, and it was a fresh server anyways) - no dice.


    I now also tried uploading the lates Debian 12.6 arm64 ISO, but it's still not booting. So, you're not alone, you're probably not using the system the wrong way, but it will probably need an intervention by Netcup to fix that.



    Cheers

    citecite : I managed to boot an Ubuntu 22.04 LTS based LiveCD using one of the ARM servers in Vienna without any problems, maybe you could try that? Even if it's Debian you want, it should be possible to bootstrap an installation like I did using debootstrap afterwards.

  • @TUNGLINWU : Just to clarify: Did you explicitly change the boot order and select the ISO image in question "in one go" using the dialogue which requires you to re-enter your password?

    I used netboot.xyz to start the Debian installer. Basically, I just installed one of the premade images, opened the virtual console and interrupted the startup process by pressing "ESC". This puts you into the minimal UEFI firmware, from there it's "Boot Manager" into "EFI Shell", and from there the usual (the "#" comments are NOT to be entered):


    Code
    FS0:  # selects the first EFI filesystem, which gets created by all of the images
    ifconfig -r eth0
    ifconfig -s dhcp
    ifconfig -l dhcp0  # this can take a bit until it's actually showing you real IP information
    http boot.netboot.xyz ipxe/netboot.xyz-arm64-snp.efi # dowonloads the netboot iPXE helper to disk
    netboot.xyz-arm64.efi  # starts the downloaded image


    The boot menu will then show you "Linux Network Installs" or something like that (there was also one previous level of commands, IIRC). In any case, I appreciate your willingness to help, m_ueberall.
