MBR boot options?

[Penetr8or]

Hi,

I wanted to install this on HP Elite8000 C2D.
This BIOS only suppot MBR and wont boot using GPT from the USB

Any suggestion please?

No problem. From the dowloads section there are options that support both mbr and uefi as install options. Obviously if you can only boot that machine from usb, then you need to format your intaller media in that way.

Thanks for the help.  I have tried burning all the images. The issue is that the GPT/MBR option (i use rufus btw) is not changeable when trying to write - the x64 is set for GPT as it says - the DVD-ISO wont burn says incorrect image type - not sure how to use the serial version - that actualy burned okay onto the USB with MBR but the PC hungs at boot.

Have you tried with these instructions https://opnsense.org/users/get-started/ ?
Maybe an issue with your software used to burn the image rufus. Maybe a windows thing.
Linux has no problems with these basic things
