Windows 7: How to change start up screen?

I send my PC to repair and they changed my start up screen. Not logo or something. I can't reinstall my computer because i don't see when booting bios and don't know how to change it and boot sequence has been changed too. Can somebody help me pls )

Sounds like your bios has multiple post options.
Usually it's accessed by tapping delete right as the system powers on
if that doesn't work F2 and insert are also sometimes used.
Once in there you'll need to find a setting to the effect of "show logo" and disable it or enable it, whichever one you are after I'm a little unclear on that.

Assist us by completing your system specs.

UPDATE YOUR SEVENFORUMS SYSTEM SPECS


User CP (3rd item in the top menu bar) |
in left-hand column, under Your Profile, Edit System Spec |


Use Speccy - System Information - Free Download
and/or SIW to gather info for filling in the blanks.

Do me a favor and add the word laptop or desktop to the “system manufacturer” block.

Use the “Other Info” block for Optical Reader, Mouse, touchpad, wifi adapter, speakers, monitor

Scroll down and click on the SAVE CHANGES button.

Edit system spec doesn't exist in my system and nothing even similar like that.

go to the search box in the startup menu and type
dxdiag
and hit enter
choose save all information and just zip and upload that, it will contain info on your graphics network and sound at least.
