bypassing secure boot

[noobs guid to marsterrace]

I have a second hand Lenovo yoga s1. I'm currently dual booting windows 10 and ubuntu on to but I want to run Kali on it instead of Ubuntu. the only problem is that kali doesn't have secure boot and the bios havs a password on it from the previous owner. is there any way of bypassing secure boot at all.

Have you tried "password"?

iv tried all the default passwords like password 1234, bios, phenx

Disable it from the UEFI settings

how do you do that if you go into recovery mode on windows and select UEFI it just reboots into the bios with the password prompt

Remove the BIOS password first, then convert your boot drive from MBR to GPT. I think forum mod @GoodBytes made a thread about that. Then you can proceed to changing your UEFI settings and disable secure boot.

I can't remove the password I don't know what it is

Found it. I don't know if there's something that can strip off the BIOS password.

Check online for the full manual of the system to know how to rest the password on a Lenovo laptop. Usually there is a special combination to do.

clearing bios password is as easy as clearing CMOS, this is why some cases have physical locks on them, all well and good having a BIOS password, but if u can get to the CMOS battery, no more password

Not really. Many OEMs saves the password on the BIOS/UEFI chip, and not in ROM. So, removing the battery doesn't clear it. You usually have a special combination to do. If you call the OEM, they can give it to you.. assuming your system is under warranty/support.

worked every time for me, only ever done it to dell machines though, mileage may vary with other manufacturers.
