I decided to switch from Windows to Ubuntu 18.04 on my laptop, an acer travelmate p.

I booted up with the USB ISO. I did a regular install, no updates. I did the delete and install style build. Install went through without a hitch.

Now my laptop boot loops. A message comes up super fast saying something along the lines of can't find boot loader, then it restarts.

When I go back into Linux via the USB, I do a parted print and I see my esp partition with the boot flag. I also see the ext4 with everything else on it.

I also tried a efibootmgr.

I got 4 results. windows as 0000, iba ge slot as 0001, my HD as 0002, and the USB im on as 0003. I deleted the Windows one, but I did notice Ubuntu wasn't on there. I'm a little stumped about what my next step would be now. Any advice?

Edit: I successfully got mint 17.3 installed weirdly enough. That gave me the idea to try 16.04.4 and then upgrading after that. The later had the same results as installing 18.04 unfortunately

Try to repair the boot with Boot-repair using the USB with UBUNTU LIVE.

So I had to reinstall windows to update bios. I went to acer download site and downloaded the most recent bios. once i updated bios it let me choose between legacy and uefi on my "boot" tab in my bios. I did set a security password again but i dont know for certain if that added anything to this process. Then I reinstalled ubuntu 18.04 and i expected to have to go back and add it to the trusted boot loaders in the security tab of bios but it booted and it worked. all is well with the world.
