[tea for one]

There are a few idiosyncrasies in your installation:-

• Grub installed in the mbr of /dev/sda
• msdos partition table
• Two vfat (fat32) partitions sda1 and sda2
• Extended partition sda3
• Old fashioned logical partition sda5

In your position, I would install again in UEFI mode with gpt

Boot into a “Try Ubuntu” live session and check that you are in UEFI mode
Open a terminal and enter:-

[ -d /sys/firmware/efi ] && echo "UEFI" || echo "Legacy"

Use gparted to create a GPT (GUID Partition Table)
Allow the installer to automatically create the necessary partitions

Edit: Any reason not to try 24.04 (either Ubuntu itself or a lighter flavour?)

[yancek]

Do you get this error when you set Boot0004* (Ubuntu entry) to first boot priority in the BIOS? Have you disabled Legacy boot in the BIOS.

You have an EFI entry for windows Boot0001*so if that actually booted, it must have been a GPT drive, at least that is what Microsoft says is the requirement. sda1 was probably the windows EFI partition where you could have installed the Ubuntu EFI files in a separate directory but apparently you deleted the existing EFI and created a second one (sda2) as well as changing the drive from GPT.

Simplest solution is to follow the advice in post 2.

[dwlcpablo]

Thx a lot guys, the gparted step helped - I created a GPT with gparted, rerun the installer and all is fine. Previously, the laptop was running a Windows 8, and i somehow borked the boot with the initial installation.
