Lenovo G50 30 - booting from CD

I've just bought a Lenovo G50 30, and I'm planning to install Linux on it. I don't want to boot it to Linux so that I can claim a refund on the Windows licence. When I boot  the laptop, it doesn't seem to give me an opportunity to go into the biops settings so that I can change the boot sequence to boot from the Linux installation CD - how can I do this?

Re: Lenovo G50 30 - booting from CD

hi Tim_E,


Welcome to the Lenovo Forums.


Can you try the following:

1. Boot into the BIOS via the UEFI Firmware Settings or by pressing the OneKey Recovery button (while the computer is turned off).

   - Link to picture


2. Once in the BIOS, set the following settings (if applicable) to boot from a Linux installation disc.


Security Tab:

Secure Boot = Disabled


Boot Tab:

Boot Mode = Legacy

Boot Priority = Legacy First


Exit Tab

OS Optimized Defaults = Other OS or Disabled



Please backup all important files and create a recovery drive before making changes to the HDD.

Re: Lenovo G50 30 - booting from CD

I have a different situation.

My G50-70 laptop had been exposed to a surge.

The laptop has been repaired but the internal HD was fried; completely. 

I bought aftermarket Win 10 software but that failed fir there is no boot drive available  

WHERE CAN I LEGALLY buy a boot drive cd software to download a Win 10 PRO OS.

Microsoft has a tool for creating a DVD from an image file - free to download.

If your computer was damaged from a surge in electricity, it may have suffered more than a hard disk failure so taking it back to the shop that repaired it would be the next step  Make sure they verify and test the HDD and all other options before you take it back from them.  Also - just an FYI,  the shop should be able to load Windows on it for you, as the "key" to the license should be either in BIOS or registered online with Microsoft. Once the OS is installed, it should be able to find either key versions.
