Why do I see multiple splash screens on Windows boot? - Microsoft Community

hey guys,

why see more 1 os boot splash screen when os booting?

so i've had laptop while (hp probook 4720s). came suse linux installed, replaced windows 7, later on replaced windows 10. did quick hard drive format followed clean install. migrated c drive original hdd ssd, switched mbr gpt , bios uefi. ever since did that, boot sequence goes through 3 different splash screens: 1 black background white "loading" bar, 1 old windows 7 loading splash screen , windows 10 loading splash screen. googling problem, found possible answer why happening:

"on mbr disk, partitioning , boot data stored in 1 place. if data overwritten or corrupted, you’re in trouble. in contrast, gpt stores multiple copies of data across disk, it’s more robust , can recover if data corrupted."

could that, during boot, old boot data being found first, because weren't overwritten during other os installs, since aren't linked corresponding os other boot data loaded next, until 1 linked existing os found?

if that's case, there way fix this, other performing full format on next clean install? 

thanks in advance,

niko
