Identical PC's and windows 8 image - different BIOS boot setting
Hi, I got two Dell Latitude E5430 PC's. One was delivered with windows 8 and one with windows 7, I made a working image from the win8 and recovered it to the win7 PC.
The thing that I do not understand (And probably is an understanding explanation for) is following;
The orginal win8 machine BIOS boot settings needs to be set to 'UEFI', but the one that came with win7 originally, needs to have 'Legacy' set to boot...?
The PC's have identical hardware, even the disk is identical.
The OS partition is GPT, if that has anything to say, and BIOS version is the same, default bios settings is also different on these two computers.
Why is the default BIOS setting different? And why do they need different settings for boot in BIOS?
Thanks In Advance!

Thanks for the enlightenment! So even if I format the disk shipped with win7 in Linux to GPT style, then roll the win 8 image onto that disk, I will be needing to use Legacy boot on the computer with that disk? Theoretically that would actually change it, isn't that right?

Formatting the drive does not affect the BIOS. The BIOS is stored on the BIOS chip on the motherboard.

Yes, i do know that. I got some knowledge within IT.
Only not that much with win8 and uefi.
But to get disk working with windows 8 and UEFI instead of using Legacy.... Wouldn't I just need to set right settings in BIOS and format the disk in Linux to GPT, and then roll windows 8 image onto the disk?

You would need to make the changes to the firmware to enable UEFI and enable secure boot, boot to the Acronis Rescue Media in UEFI mode, use the Acronis tool "Add a new Disk" and initialize the disk as GPT without creating any partitions, then restore your Windows 8 image to the un-allocated space on the GPT disk, making sure of the correct partition order as well as marking the correct partition active.

Yeah, I did make the changes in BIOS... tried that in Acronis too, but if i set UEFI to boot, i get the error Invalid Partition Table... but if i set back to Legacy, then it boots just fine, No MBR on it, and using format drive in Linux aswell as doing the add new disk to initialize GPT style in Acronis...
