What happens when you try to fix a glitched boot order in your BIOS for an Acer Nitro AN515-55?
Hey everyone, I put a Linux-based operating system on my laptop with a bootable USB drive. Now I'm trying to make Windows and Linux both work at the same time (dual boot). I think I messed up the USB ports on the laptop because now, when I plug in that working USB, the computer's BIOS settings are acting weird. It looks like there is nothing listed, but one option is blank. If I press F5 or F6 to move things around, strange names show up that aren't actually my USB drives. I didn't make any major changes except switching from RAID to AHCI because Linux wouldn't see the SSD otherwise. I checked and confirmed that the USB stick is working fine, but this problem happened before too and I solved it by changing the ports. But now that doesn't work either. Is there something else I can try?
boot into UEFI mode and clear the cache there from your UEFI firmware. You can get UEFI shell from github, in most UEFI bioses you can start it from boot override settings. https://kmpic.asus.com/images/2020/12/16...c51960.png here are two examples once you start UEFI shell, then use this command to see your current boot options bcfg boot dump -b all. All boot entries get numbered so you can remove a specific one with bcfg boot rm 2
Thanks for your reply, but I am having trouble going into the UEFI shell... I can't change the boot order to use the USB where you downloaded GitHub software from, so I tried finding a way in through the BIOS firmware and found a Boot Mode option (set to 'UEFI') that is grayed out and cannot be changed. I don't know why this happens. Also the firmware I'm using is Insydeh20 Setup Utility version 5.0
