i dont know why acer released 3 bios update of version 2.xx but still cant install to the laptop.

 

When i tried to install it, it says "Please update to the same type of BIOS (1.xx)"

 

PLease help me im using Windows 10 Home right now but on legacy bios i cant shutdown my laptop properly because it will restart again, not shutdown

How can i understand which version i need to download?

Laptop versions:
1.xx can only be updated using 1.xx versions
2.xx can only be updated using 2.xx versions (normally 2.xx version are labeled "not for upgrades")
 
Desktop versions:
P01.xx can only be updated using P01.xx versions
P11.xx can only be updated using P11.xx versions (normally P11.xx version are labeled "*not for upgrades")

"L" BIOS versions are Linux OS dedicated (example P01.xxL)
 
* what does it mean "not for upgrades"?
During the windows 7 to 8 transition, some PC models had different BIOS versions from factory, related to the installed OS.
Windows 8 PC got an UEFI BIOS
Windows 7 PC got a "Legacy" BIOS

So PC with Windows 7 installed from factory can't use the "not for upgrades" BIOS version, even if they were upgraded to Windows 8 or 10, since the factory BIOS was a different version compared to PC with Windows 8 from factory.

you can install windows 10 using UEFI, just create the proper USB installation media.
