It really depends on the hardware of the laptop from which you are booting. If you have BIOS rather than an Extensible Firmware Interface (also known as UEFI or safe boot), the present version of GRUB does not install correctly. For a BIOS machine with GPT partitioning, you must install a small ~256M FAT partition with BIOS GRUB and legacy boot flags set as the first partition, before a ~256M /boot/efi partition which is FAT16 formatting flagged boot and ESP which is needed to finish installation with the present installer, then your swap partition and /, /home, or whatever other distribution and personal preference ext4 or whatever partitions. While still in the live installer or from a boot rescue, you must then open a terminal and execute the following if your boot flash drive is /dev/sda::
$ sudo update-grub && grub-install --target=i386-pc /dev/sda Note: For later versions, ie. Xubuntu 23.04 nightly, you may also have to copy the i386-pc folder from a 20.04 installation. After much research, this is how I keep up my BIOS AMD Athlon II machine.
