So the machine will likely not boot from the factory OS. These new BIOS's might not list other bootable USBs. In fact a few fail to boot anything but EFI. I can't know this, way too many models out there.
I see at https://imgur.com/zYH7QHI the reset and restore which should get it running again but I can't tell why you need to boot and what you want to boot which some find prying but it can matter. Some machines arrive with W10 and folk want to install 7 but what a mess as there are no drivers.
Anyhow, most of the time it's to install some Linux so I try the F9 key on power up to see if my current Linux distro on USB shows up.
Last 6 hours after i got new laptop, been trying to find a ******** USB boot option, no luck tho and i'm really hoping to receive help here. I'll explain issue in detail with pictures of bios with all that i have tried.
Laptop model is Lenovo IdeaPad 330-15ARR, here are specs

When I got laptop i had SSD boot, IPV4 can't remember 3rd, it was saying 'locating media'.
After persistent attempts I might have f*cked something up.
Cause now I can't see any bootable devices, here's error i get.

I was trying to disable secure boot, to enable legacy mode, for usb...
also tried changing os optimized defaults, and then reseting to default (one was for win 8.1 and 10) and other one supported legacy mode.
All attempts were in vein and i couldnt see, most of time i spent trying to install Linux.
Then I thought maybe ok, it's compatible only for win10, so i made bootable usb with win10, but it didn't change anything... Here are pictures of BIOS
Here, after error this is what i see from boot options

(i think its worth noting that legacy and UEFI make no difference as i don't see anything, except the fact i see other than EFI, there are no options for booting, or even seting a priority...)

I have spent a lot hours on google trying to figure out whats up, basically nothing of it helped USB boot option appear, only made everything worse, ( i didnt get error from first picture on start... ).
I hope i can be helped and not going to have to send it to service ![]()
