Motherboard Manufacturer and Model : Acer Aspire V3-571G -Bios Revision : 2.15 -Bios Type : Insyde Bios -Bios SLIC: v2.1 -Bios Link : http://global-download.acer.com/GDFiles/BIOS/BIOS/BIOS_Acer_2.15_A_A.zip?acerid=635067212785876098&Step1=NOTEBOOK&Step2=ASPIRE&Step3=ASPIRE%20V3-571G&OS=ALL&LC=en&BC=ACER&SC=EMEA_27 OK, here's where the story starts. I bought the laptop with Win8 installed. Used GParted to remove, then installed Win7 Pro. I think the 2.xx series bios are for Win8 so I now boot legacy (booting UEFI leads to "no bootable devices found"). I am looking to unlock the full BIOS menu. So if anyone can mod the BIOS above or explain how to downgrade my BIOS to 1.xx series I would be a very happy man. Thanks in advance.
