openSUSE 13.2 64bit KDE 4.14
How do I delete a boot loader entry with YaST? Advice on the Internet tells me to select the item in YaST and click “Delete”. But I must be blind because I don’t see a “Delete” option.
Thanks in advance.
If you are using “grub2”, then you are probably concerned with entries that are automatically added.
You cannot delete those.
Well, okay, you could edit “/boot/grub/grub.cfg”. But those entries are likely to be added back when the file is regenerated. There might be some changes that you can make in “/etc/grub.d” that affects how “grub.cfg” is generated.
If you merely want to remove some stale entries, then perhaps regenerating the file is sufficient. The “update-bootloader” command (as root) should take care of that.
It all depends on what entry you are referring to.
I take it you want a Grub menu entry removed?
Specifically, what is the entry you want to remove?
I need more details.
Grub2 is being used. sda1 is a bootable partition holding openSUSE 13.2 my current stable, everyday distro. sda2 holds an unstable LEAP 42.1 I have temporarily abandoned but do not want to delete. I want to remove the entry that boots sda2, and not to have it re-appear at the next grub update.
This is my grub.cfg…

You can turn off the option: “Probe foreign OS” in Yast bootloader. Then it will only provide boot entries for your main system and for entries you add yourself such as in “/etc/grub.d/40_custom”.
It won’t find Windows entries, but I don’t think you have any.
I normally turn off that option when I don’t have Windows installed.
Thank you very much. A simple solution I should have seen, but I was looking elsewhere.
… the very thing I was going to suggest, but first wanted to be certain what you were trying to achieve. Glad nrickert jumped in and you are now (I presume) satisfied.
