How do I change the boot order

I want to change the boot order so that if I have  USB plugged in it will boot off that. I can get it to boot off the USB by interupting the boot and selecting the USB, but I want it to do that automatically.

 

I can get in to the BIOS setup and find the Boot section but it only seems to give me options of UEFI or Legacy, no option for USB. I'm used to computers that have sensible options of Hard Drive, Optical Drive, Floppy Drive and USB.

Re: How do I change the boot order

hi Nina_W,

 

Depending on the model and the BIOS version, newer Lenovo systems are preloaded with the Unified Extensible Firmware Interface (UEFI) and has a feature called Secure Boot (which is enabled by default) to protect the OS from loading any third party boot loaders / drivers (or even viruses) from loading during the boot process (this includes booting from the USB).

 

To automatically boot from a bootable UEFI USB flashdrive, the BIOS must have the following settings set:

Security Tab:

Secure Boot = Disabled

 

Boot Tab:

Boot Mode = UEFI

USB Boot = Enabled

Boot Sequence = USB Key

 

Exit Tab:

OS Optimized Defaults = Other OS

 

If the USB Boot / Boot Sequence is missing in the BIOS, you will not be able to automatically boot from a bootable USB flashdrive. Instead, you will need to press F12 during boot-up and choose the USB key or follow this guide to boot from the device within Windows.

 

 

Regards

Re: How do I change the boot order

It seems my BIOS is one of the disabled versions that don't allow this basic facility! I can get it to boot by interupting the boot sequence and selecting the USB but I have to be really quick and it doesn't always work and carries on straight to Windows.

Re: How do I change the boot order

Have you tried resetting the bios? If not try it by powering off the notebook, remove AC and Battery, press and hold the power on button for more than 15 seconds. Re-insert the battery, attach AC power and start up your notebook, enter BIOS and attempt to make changes.

Post back with the results please.

Re: How do I change the boot order

Hi,

 

If you'd tell us what model laptop you have, someone may have a suggestion.  For instance, if you have a Novo button, powering on via that should give you boot options without the tricky timing window.  There also may be some other option in BIOS worth exploring.

Re: How do I change the boot order

It's a B590.

 

 

I'm reluctant to try taking the battery out as I can't see what that would do. Is it possible that the BIOS could have got corrupted in some way to just not give an option, rather than corrupted in a way where it just wouldn't work properly. its not that I'm selecting the option to boot from USB first and that's not working. The option just isn't there.
