start up problems on my HP AIO - likely a windows 'leftover??)

English Install/Boot/Login

When I installed Leap 15.2 on that machine, I ‘thought’ I was ridding it of anything windows. Apparently not!
This image is the partition table https://susepaste.org/89206482
The top partition (100 MiB fat32) is an EFI SYSTEM PARTITION ( think that is a windows leftover) and is labeled ‘boot, esp’
The highlighted partition (100 MiB fat16) is a ‘boot/efi’ , and is also labeled ‘boot, esp’
The fat16 partition was set that way by the installer, and I din’t change it for fear of messing things up(which I did anyway);

Can I just delete that top partition, and hopefully get on with things ?
OR
Can I somehow clean off that drive and reinstall Leap 15.2 without problems.

I took a picture of the BIOS boot options showing the UEFI disabled, but it keeps coming back after I shut the machine down for more than a few minutes.

So I have to go there to boot into ‘opensuse-secureboot’

In that 1st picture, the top partiton is on /dev/sda1 and in the BIOS recovery option, Windows boot manager is on /dev/sda1

I just found that digging deeper in the BIOS.

Having that partition is not a problem.

It would have been better if the installer had just used that EFI partition ("/dev/sda1") instead of creating a new one. It looks as if they might get that right in Leap 15.3.

If you don’t have anything of Windows left on the machine, then it won’t hurt to remove that partition.

I’m thinking about re-installing from scratch. There are a couple of partitions that I don’t know ho they got there. Both show as unallocated and are fairly large sized(GiB instead of MiB). I meant to have boot, swap, / and home partitions on that machine. I don’t know if the installer decided I couldn’t do that and added the unallocated partitions on it’s own.

Thanks for the reply, I will remove that windows system partition, and see how things go. If I still have problems with start up, then likely do a fresh install.

15.3 is still a long way off isn’t it? That is why I put 15.2 on.

Yes. It will be 6 months or more before it is out.

ILL you’re trying to install legacy boot Linux on EFI Windows drive.
IMHO it is better to use EFI Linux on a modern hardware.
You may use /dev/sda1 as the only one ESP (EFI system partition), for both Linux and Windows.

Unfortunately, the installer will complain about that, because “/dev/sda1” is smaller than 256M. To do what you suggest, requires using the expert partitioner and configuring “/dev/sda1” to mount at “/boot/efi”. And then when a warning message comes up that there isn’t an EFI partition of at least 256M, you have to tell the installer to ignore the problem and just continue with the install anyway.

That’s what seems to be fixed for Leap 15.3 (currently alpha-testing).

If you’re hinting on this, then complains about size may preserve.
