Re: IdeaPad V570 bootmenu

hey energycsdx,

this bootmenu that once existed before the BIOS update ... did your unit have both a windows and linux OS installed ?

Re: IdeaPad V570 bootmenu

yes, i have windows and linux installed.

 

now i boot to windows througt UEFI chain.

and to linux througt BIOS using USB stick with grub.

 

as i understand one of feature of UEFI that it is boot menu stored in NVRAM and UEFI starts proper OS Loader stored on EFI System Partition, but looks like this was disabled in recent BIOS (firmware it would be proper to say)
