    23.04 fails to install GRUB

    Hi there,
    with the new 23.04 also debuted the new installer but with older PCs it gives problems and fails to install Grub. Is there any way to get a "legacy" iso for Xubuntu (XFCE) or does it not exist?

    thank you

    The iso with the legacy installer is here:
    http://cdimage.ubuntu.com/ubuntu/rel...23.04/release/
    Sorry..this is for ubuntu, not xubuntu.

    The Xubuntu iso is here:
    http://cdimage.ubuntu.com/xubuntu/re...23.04/release/
    but you probably know this. I don't see anything with legacy in the name, so maybe Xubuntu did not use the legacy installer?

    How is grub failing?
    If gpt partitioned drive you must have bios_grub partition on drive you are installing grub into.
    If installing in BIOS mode, you must specify a drive like sda, not a partition like sda1.
    If UEFI install, you need an ESP - efi system partition on first drive, not necessarily on install drive?

    sudo parted -l

    My PC (hp 260 g1) has BIOS system (something as this https://it.easeus.com/images/partiti...tup-screen.jpg)

    The error I get is (as alert at the end of installation process) is:

    Unable to install GRUB on /dev/sda Execution of "grub-install /dev/sda" fails, fatal error
    I can't make nothing of complex, just make a USB pendrive with Rufus and reboot the PC

    Post partitions with parted.
    UEFI or BIOS install?

    All models of HP typically needs extra settings in UEFI or configuration steps. It does not support efibootmgr which grub uses to install grub in UEFI mode.
