Can't boot into OMV after CMOS battery died. Some bios setting.

as above I can't seem to boot into OMV after this CMOS battery died and reset the bios to defaults ive tried SO many setting and it will not boot! I have a HP Z620 workstation as my "server" all I get is a "_" flashing and that's it

Does anyone have any ideas what setting in bios I need to turn or/off to get it to boot again. I know its nothing to do with OMV just after some help.

Sadly I have no idea what setting was on the bios when I bought it.

I don't want to have to install everything again and start a new if I can help it.

Thanks.

If you can't get it to boot to your OMV disk, what makes you think a reinstall of OMV will change anything?

Very helpful. I image it would change from UFI to GPT. if I reinstalled it. Are you always this much fun?

You're taking this in a wrong way.

If you just try to re-install Debian as it is now, the drive might not be seen still.

I know.

If the BIOS went to "defaults", you should start by seeing what you need to change to make the boot drive to "boot"

Like? ive change every item in the bios to try and get it to boot.

If I go the run a uefi application and go into the debain folder it works. Just will not "auto" select this bloody drive

Have you set right time and timezone in bios after changing cmos battery?

Yes its correct Thanks.

Why do HP have to make things hard. why can I boot just fine if I run a uefi application from the bios option yet when I get it to this drive all I get is a blinking "_" on the screen.
