Dear community,
I have a problem with my DH87RL (Rev 401) with the latest Bios-Version RL0326.
After installing Win 8.1 64bit on the SSD (8 months ago) everything was fine. I have 2 optical drives, a SSD (EVO 840) and a Seagate HD (also with bootable Win 8.1). All these drives were shown in BIOS and in the boot-manager (UEFI mode and legacy mode). When I pluged in a USB stick (e.g. Ubunto or Win PE) I could also see it in the BIOS and the boot manager and I was able to boot from the stick.
Now I have the following problem: I couldn't boot from a USB-boot-stick that was displayed in the boot manager. Therefore I disabled the legacy mode and once I had booted again I switched it back on.
Now when I choose the boot-manager using F10, only my SSD and the UEFI : LAN connection are displayed. The Seagate-HD and every USB-boot-stick are missing. In BIOS, under UEFI boot page, all drives (except the optical drives) are available and I can boot from the HD with a double click. Under the legacy boot settings everything (optical drives) is missing
I already tried the default values without success.
I assume that I should erase the NVRAM or are there other solutions for this problem?
If I must erase the NVRAM, how best to do it (remove the BIOS battery)?
Thanks Mike
