EFI Boot Logo Follies

EFI Boot Logo Follies

It’s been an interesting last couple of days. I really like the boot logo from the Lenovo Yoga Pro 9i. It’s popped up often as I’ve been reviewing it since the end of April. But I’ll be darned if I can find or  extract that file from the UEFI image. Along the way, I’ve indulged in all kinds of fascinating, down-the-rabbit-hole EFI boot logo follies.

You can see some evidence of this in the high-relectivity photo from my iPhone. It shows me shooting the logo from the Yoga’s initial boot screen. It’s been a gas. But so far I’ve been unable to grab the  bitmaps that animate this logo during the boot process.

Where My EFI Boot Logo Follies Have Led…

I started down this trail by using MiniTool Partition Wizard to examine the contents of the EFI partition on the Yoga. Alas, nowhere did I find a neat, discrete bitmap (or set of bitmaps, as the runtime animation strongly suggest must be buried in there somewhere).

Next I tried my luck with the HackBGRT, specifically designed to use the MS Paint app to drop another bitmap into UEFI to take over for the existing one. Despite my hopes it would let me see (and grab, even) what was already in there, no such luck.

My search for copies of this file online have gone unsatisfied. I’ve dropped a request to the reviews coordinator at Lenovo, but have gotten no response. I’m going to ping one of their SMEs and see if they can talk to the UEFI builders and help me out.

All I Got Was a Lousy T-shirt … err iPhone Grab

Amusingly enough, the iPhone snapshot I took of the logo shows me taking that picture. Ordinarily, I wouldn’t reproduce such an amateur, ghastly image here in the blog. But it captures perfectly the “chase-my-tail” exercise I’ve been going through trying to lay hands on the original Yoga Pro 9i boot logo. It’s right there. I can see it every time I boot. But that’s as close as I can get right now…

Simon Allison Comes Through!

When I checked into LInkedIn this morning, the former Windows Insider MVP named above posted a link to the graphic. Now you can grab it, too. Here’s what it looks like (and THANKS, Simon):

This doesn’t show the animation (you’d need the full set of images for that). But hey: there ’tis as a profound demonstration that we’re all better together than separately.
