Hello Archers, I am planning to install Arch on a dual boot with windows 10. But i have read online that on a dual boot with windows 10, the bootloader will disappear after a windows update and can be cured only by using a live usb. They say that it is for general linux dual boot and not specific to our Arch. Before trying for myself, i would like to know whether anyone here have faced it before, if so, what is the better solution to it?.

I need windows too because of ansys package that i use.. could you please help me with this?

create a USB-Key, install extlinux onto it. In extlinux.conf, you can provide kernel cmdline, with root=UUID=xxx-xxx-xxx-xxx In that way, you can boot your archlinux(and any other linux) from USB, and using your main HDD(partition) as the rootfs.

Note, every time you update the kernel, you must copy the updated vmliuz + initramfs.img into you USB disk.

That is not a LIVE USB-Key, it just an bootable kernel + initramfs. Not a completed OS.

You can do that just in case but I don't think it will be necessary. I am using Arch for years now in 3 different UEFI computers with Windows 10. Just follow the installation guide and boot loader wiki page. Just like Jason and Artur linked, wiki warns you for possible problems before you face them and suggests fixes. In case you wonder, I am using systemd-boot with (almost) default configs. Never used GRUB with Arch but it doesn't cause any problems on other Linux distros (at least for me) with Windows 10 dual boot so it is a safe bet too.

I will go through the links guys, thanks a lot.. And Yi Zheng, me neither like UEFI, but what to do, nowadays all laptops comes as UEFI.. and to change it to MBR i have to wipe the entire drive :( On Mon, 27 May 2019, 12:31 pm Yi Zheng via arch-general, < arch-general@archlinux.org> wrote:
