Can't dual boot with windows

Hi, I'm trying to get a dual boot arch and windows system. I installed windows 11 first, and it's a GPT disc. I reduced my c: partition by 60 something gb to have space to install arch. From there I manually prepared my arch partitions, setting up a 1gb EFI as xbootldr, in the end I had my original EFI partition, my linux extended boot, and my /. I formatted both new partitions, and then installed using archinstall. Upon reboot, I get a menu, but the menu only offers Windows 11 and the system doesn't seem to want to boot to arch, what do I do? I followed the following guide. Thank you kindly, this is important. I was able to successfully get debian to dual boot with windows but I hate it.

Re: Can't dual boot with windows

I followed the following guide.

https://nic96.dev/blog/beginners-guide- … x-windows/

then request help from its author

to spare everyone else the time:
- blog post, "work in orogress", from jan 30th 2025
- pre-mounts /efi and /boot
- just ends with "use archinstall" without even guiding through it

the "guide" is incomplete - useless
also: by chance is this a laptop?

Re: Can't dual boot with windows

ok.
u can install it to separate disk if you have it and then you can in boot menu just boot the disk but here its a chance that windows won't count the time same on linux, but not always but most of 99% won't count. (timedatectl set-local-rtc 1 --adjust-system-clock). I would do that. but if you dont have another disk follow this:
- i think on windows is something called fast boot. turn this off cause the disk is locked and you can't boot Arch Linux.
cause the windows just hibernates the disk.

EDIT: the blog is super useless. its says to mount partitions by yourself and then he uses archinstall.
try official arch wiki. and Good Luck!
