@SIW2 Do I need to replace the acpi.sys in C:\Windows\System32\drivers after the installation? Thanks!

--------- edit ---------
Replaced acpi.sys after install, but still can not boot Windows 7...

- The IdeaPad 100-14IBY has official support to Win 7.
- Your BIOS is updated

You shouldn't have any problem installing Win 7
The only thing I can think about is the Win 7 installation files and / or BIOS settings.
In what language you want to install Win 7?

Win7_HomePrem_SP1_Dutch_x64.iso

Win7_HomePrem_SP1_English_x64.iso

To make the iso file universal (all Win 7 versions) you need to apply View attachment eicfg_removal_utility.zip. Read the read.me file.

Just seen this video: Instalar Windows 7 Lenovo error pantalla azul ACPI compliant error. - YouTube
Fixed : The bios in this system is not fully ACPI compliant - YouTube
On the BIOS exit tab, you select OS optimized defaults = Win7 or Other
Then Load Default Settings

Thank you all, it finally worked. I only needed to set the BIOS to default. After that I changed to Legacy mode and OS optimized defaults to disabled. Win 7 running now !!!!!
