I'm trying to follow tutorials for installing a dual-boot Windows/Ubuntu setup on my Dell G5 5500 laptop. I'm supposed to visit the BIOS and do the following:

  1. Disable secure boot
  2. Disable Legacy ROMS
  3. Disable Fast Start

It's been almost a decade sine I had a Windows laptop and geeze, BIOS has changed! This Dell BIOS supports using the mouse, searching, etc and is pretty fancy. But it does not match any of the videos I've seen sadly.

I successfully performed item #1 (disable secure boot) but could not locate the other settings. Upon reboot I was locked out because I now need (apparently) my BitLocker key to boot because I disabled secure boot. I had to re-enable secure boot to get back to Windows.

When I do this again I'll be prepared with my BitLocker code: Will I just need to enter it this one time or is this going to be a permanent boot-time chore? Any ideas on locating those other BIOS settings or advice specifically for my G5?

On Windows Check if bitlocker is enabled, if so, disable it. I've disabled secure boot on my Dell Latitude E6430, and it's all ok. Fast start or fast boot are the same I guess, I have it disabled to, it should be in the boot menu in the BIOS. I have Legacy turned on. I don't know how you prepared your installation media, I've used ventoy. Good luck :)
