| How to disable UEFI on Acer Aspire laptop and switch from WIndows 8 to Windows 7 | |
| Disclaimer: follow the steps at you own risk, I am just relating my experience with this situation. You may invalidate the laptop warrant by changing the factory configurations. | |
| To enter factory BIOS turn off the laptop and then turn on. Press F2 during the boot until que BIOS screen appears. With the directional keys select the tab Boot, tap Enter then use up and down keys to switch between UEFI and Normal BIOS. | |
| Now the laptop is ready to boot an usb stick or DVD. | |
| If the Windows 7 installation fails with this error: | |
| “Windows cannot be installed to this disk. The selected disk is not of the GPT partition style” | |
| just follow these steps to solve it: http://technet.microsoft.com/en-us/library/dn336946.aspx | |
| Warning: commands cited in the link above may clean the windows 8 backup partition, so after running them it is unable (as far as I know) to access the UEFI recovery screen and rollback to Windows 8. Be sure that you really want to throw away windows 8 and just stay with windows 7. |
