Systemd boot, dual boot arch/win 10 bios boot order

My windows 10 install ended up with a virus, I had both a DD'd image and a clonezilla backup. I tried restoring with clonezilla first and instead of my normal boot menu I was greeted with windows. I decided to try the DD image I made to see if it was any different, but no. I booted Arch live off usb and double checked that it was installed right. I can hit F12 to get to my boot menu where it allows me to choose between Arch, Windows, and USB, I'm able to boot either OS. I figured this just meant I needed to change the setting in bios to select the Linux bootloader as default, I cannot change this setting. I hit enter and instead of seeing my different boot options my bios freezes and I have to hold down the power button.

My laptop is a 1st gen Lenovo Yoga 12, So far aside from this boot/bios issue everything seems to be working properly. I'm not quite sure what to do next, before the virus my laptop was set to boot Arch as the primary OS, I had to select Windows from the Linux boot menu. I have very little experience with UEFI, when I setup my laptop initially I recall no issue with the bios freezing when changing the boot order. Fast startup in windows is disable, that was one of the first things I checked, secure boot is also definitely off. I was reading about efibootmgr but don't recall using it when I setup my laptop to dual boot.

I've heard UEFI bios can be broken/corrupted and atm I'm kinda worried that's what happened, I don't want to tinker and make it worse without knowing what I'm doing a bit more thoroughly. At this point at least I can boot both OS, I'm currently fighting with Lenovo to uphold the warranty it says I have on my laptop according to their website(I'm experiencing ghost clicks and I'm pretty sure they are going to refuse to fix it without me paying for a new motherboard and labor...), Lenovo is terrible when it comes to warranties and I'm starting to wish I'd have bought a different brand of laptop...

Re: Systemd boot, dual boot arch/win 10 bios boot order

I was trying to change my boot order from within linux using efibootmgr but I'm not sure how since linux boot manager doesn't have a number with it

sudo efibootmgr
BootCurrent: 000A
Timeout: 2 seconds
BootOrder: 0000,0001,0002,0003,0004,0008,0009,000A,000B,000C,000D
Boot0000* Windows Boot Manager
Linux Boot Manager
Boot0001  Setup
Boot0002  Boot Menu
Boot0003  Diagnostic Splash Screen
Boot0004  Lenovo Diagnostics
Boot0008* USB CD
Boot0009* USB FDD
Boot000A* ATA HDD0
Boot000B* ATA HDD1
Boot000C* USB HDD
Boot000D* PCI LAN
Boot0012  Startup Interrupt Menu
Boot0014  Rescue and Recovery
Boot0015  MEBx Hot Key
Boot0016* IDER BOOT CDROM
Boot0017* IDER BOOT Floppy
Boot0018* ATA HDD
Boot0019* ATAPI CD

I'm quite lost and don't understand why there is no number for Linux Boot Manager. I have my EFI partition mounted as /boot. I have a separate root and home partitions in addition to the partitions windows made when it was installed

'man efibootmgr' contains a section about adding a new entry. Maybe try that.

Re: Systemd boot, dual boot arch/win 10 bios boot order

I managed to use efibootmgr to add the entry, now it has a number. I was able to the linux to boot first and it worked till I booted into windows. After rebooting from windows not only was my boot order changed but now I have two entries for windows, I saw something in the arch wiki about windows changing the boot order, I'm gonna have to find it again and also figure out how to remove an entry...

In case anyone comes across my post while trying to remedy a similar issue, all I had to do was select arch in the bootloader menu and tap a single key on the keyboard to set arch as default OS.
