Ok, so, I recently bought an iBuypower gaming laptop which is basically a rebranded MSI GT60. I have been extremely satisfied with it so far. My only complaint has been that the Bigfoot LAN option ROM is enabled, and I cannot disable it. If I select to disable the ROM, it enables itself again on the next boot. After playing around with the BIOS I noticed it is booting in legacy mode. Upon setting it to UEFI mode, I no longer get the option rom message. Then, like expected the machine does not boot as the disk is not formatted to GPT and Windows 8 is not set up for UEFI boot.
My question is; if I were to use the windows 7 system image tool to backup the install, then wipe the disk and convert to GPT, would the same system image work after a UEFI install?
