I installed the Leap 42-3 on an Asus RT5390 notebook
After that, the setup was modified and the HD boot disappeared and was only booted by CDROM
How do I put the boot on HD?
Do you have any data on this computer? (to know if you can reinstall without problem)
else if the computer is recent, chance is it uses UEFI and you should find a boot manager there
jdd
UEFI ? What is it? Where do I find this?
I’m trying to install again. This time I chose GRUB2
Put the CD/DVD back in the drive, choose ‘Boot from harddisk’. If that works, use YaST to reconfigure your bootloader.
UEFI is the name of the new BIOS since some years. You use it if you see a /boot/efi folder. When you use this firmware, it’s the firmware/bios/uefi, whatever name you use, that choose the system to be started (Linux, Windows…). Then you have to use grub2-efi.
But it may happen that even with UEFI firmware you use “CSM” compatibility mode and then only Grub2 (non efi).
Very recently I had great problems to boot openSUSE from a HP laptop for this reason, UEFI firmwares are not that well done and very buggy
jdd
How i reconfigure the bootloader?
as said: use yast 
jdd
I logged into YaST2 -> System -> startup, is it?
yes. Change anything and save.
check what grub version is used
jdd
I tried to do a new install, this time using the whole hd.
Now bios does not find grub and does not start
I’ve tried installing 3 more times and it always gives the same problem
It seems that I lost this notebook
do not stop too fast
First I do not understand yet if you install using grub or grub-efi. When you boot the cd, boot on “rescue”. log a root (no passwd).
fdisk -l will show you what partition are on the disk and if it’s GPT or MSDOS
say so here, and stop reinstalling
UEFI install and MSDOS install do not boot at all the same
jdd
There are several options. Which one should I use?
First you need to answer jdd’s question (#12) as to whether you are using grub or grub-efi. It’s difficult to advise when we are unsure of exactly what you are doing.

Where do I find this information?
Yast-system - boot loader
There is enabled the option “GRUB2”
LANG=en fdisk -l
Disk /dev/sda: 298.1 GiB, 320072933376 bytes, 625142448 sectors

Then you are booting Linux using MBR not EFI
TO change in Yast Partitioning set the /dev/sda5 EFI System to mount as /boot/efi in Yast -system boot loader change to grub2-efi save change and reboot
I did the “/boot/rfi” assembly and it was ok
In the Yast -> System -> Boot Loader
I change to “grub2 for efi” But when I try to save the configuration
It comes with this error message below
