I have a laptop with 2 SSDS (nvme0n1 and nvme1n1).
On SSD nvme1n1 I have installed Ubuntu 24.04 and Windows 11.
On SSD nvme0n1 I have Unbuntu Studio 24.04.
After I replaced Ubuntu studio 24.04 with OpenSuse Tumbleweed, I only could start Windows 11.
I could not start Ubuntu which is on the same SSD. I could not start Ubuntu and Opensuse because I do not see a boot menu. I do not get (error) messages.
I installed OpenSuse Tumbleweed, by first deleting the Ubuntu studio 24.04 partitions and then installed OpenSuse Tumbleweed with a live CD on the free space of the nvme0n1 SSD.
For OpenSuse Tumbleweed I used the default btrfs as filesystem type.
After installation I saw I had 2 EFI (FAT32) partitions, 1 EFI partition on SSD nvme01 and 1 on nvme1n1. Because I also had a clonezilla backup of my EFI partition on nvme1n1 (the SSD with Ubuntu en Windows), I tried to restore the EFI partition. But this restore did not my boot problem.
I think this was caused because the boot information was not stored on the EFI partition on SSD nvme1n1 but was stored on the EFI partition of ssd nvme0n1 (where Ubuntu studio 24.04 was installed before I installed OpenSuse).
When I restored the clonezilla backup of this EFI partition backup, my laptop won’t boot either.
What installation steps do I have to follow with my OpenSuse live CD, so I can start my laptop with Ubuntu 24.04, Windows and OpenSuse Tumbleweed?
Please help
