Re: idealpad b50-70 can't boot from CD

hi ditosho,


Welcome to the Forums.



Can you try these steps:


1. Boot into the BIOS (by pressing F2 or Fn+F2 on power up) and set the following settings:


Exit Tab:

OS Optimized Defaults = Win7 OS


When finished, choose Load default settings (just right above it) then set these additional settings:

  - Link to picture


Security Tab:

Secure Boot = Disabled


Boot Tab:

Boot Mode = Legacy

Boot Priority = Legacy First


2. When finished, hit Fn+F10 to save and exit and boot from the Win7 USB installer and observe if you can now boot from the Win7 disc.



Let me know how it goes.
