rx 4640 lost boot entries

Hello

What can be a reason for losing boot entries (HP-UX, efi, cd-rom ...)

Is it damage efi partition, maybe some battery or this is only possible to do manualy.

Thanks

You can delete them.

If the system board is replaced, the values are gone with it.

Better to save them and keep this copy (using nvrambkp.efi).

Hope this helps!

They are stored in NVRAM, usually a safe place.

Recreate them.

I would boot up hp-ux, then use "setboot" to configure the entries.


Do you boot from internal disks or SAN?

Hope this helps!

Re: rx 4640 lost boot entries

Perhaps the NVRAM battery is failing on you? Not sure if the rx4640 logs these types of messages into the MP, but may be worth checking (SL from MP Main Menu). If so, you may have lost your MP LAN settings as well (use LS/LC to check/config).

Torsten has good advise though...download the nvrambkp.efi utility to your EFI partition to back this information to your hard drive.

Hi,

Just one thing.. if you are talking about not seeing an option on EFI boot manager. Yes, you can delete a boot option. Not sure if that was part of your question. :)
