Problem solved by replacing mobo (same model) and getting a PS2 mouse. Now I get mouse the first time I boot to WinPE on USB flash drive, though sometimes it's the PS2 mouse and sometimes it's the wireless USB mouse. Go figure. Does anyone really know what a UEFI BIOS is really actually doing?

Sorry, this is all gibberish to me. Acronis and EaseUS both build the iso image internally and allow no interaction. New discovery: I can press the hardware reset button one sec after telling it to boot the first time, press F12, tell it to boot again and let it go through and it works fine. This is a BIOS UEFI problem. I am pursuing with Gigabyte. Thanks for your time!

How does this affect what's on the USB flash drive? Change it in the WinPE's registry. which would be where, please.

Just installed Win AIK on 11-19, so I have whatever version that is. I use WinPE for bootable USB flash disks for Acronis and EaseUS recovery, so it is Acronis and Easus that is/are grabbing WinPE and putting it in the image. I have to boot twice to get mouse. Happens with Acronis and EaseUS WinPE. I have a genuine MS wired mouse (USB), and a Logitech M510 Wireless (USB) mouse. I get neither on first boot. I get both on second boot. Always. I get mouse working on first boot on my laptop (2yr old Lenovo V570). I am guessing it's the BIOS, but any ideas as to what to change? I am running Win7 Pro x64 SP1 current and have set BIOS to "other OS" (I set OS TYPE to Win8 so I could set CSM Support to "never" and then set OS TYPE back to Other OS) EDIT: I had EaseUS todo backup workstation 6.1 write WinPE to a CD and get the same behavior - no mouse on first boot, mouse on second boot. UEFI doesn't like WinPE. EDIT: the board came with the latest BIOS - F4. It is a rev 1.1 mobo, which is the latest. EDIT: sorry for duplicate post - computer hiccuped. please delete the other one.
