After setting up dual boot, Windows won't load unless I boot into Linux first and then reboot.

After finding that I was unable to do everything I needed in Linux I wiped everything and set up a dual boot. I have Windows installed on an ssd (sdb), Manjaro (KDE Plasma 5.18.5 on kernel 5.6.15-1-Manjaro) installed on an nvme drive (nvme0n1) and a third data drive (sda). I used the following guide to set up dual boot: [HowTo] Dual-boot Manjaro - Windows 10 - Step by Step including disabling fast startup and hybrid sleep.

When I enter GRUB and select Windows, if I haven't booted up Linux immediately prior, it just gets stuck on the spinning circle with the windows logo. I then have to hard reset, boot into Linux then restart into Windows again (where it works fine). The only way for me to boot into Windows cleanly is to switch the machine on, boot into Linux, restart, then select Windows.

I set the data (sda) drive up as a universal storage drive between Windows and Linux so it is set as a single NTFS partition. Initially this drive didn't automatically mount in Linux so I modified the fstab config file with the following:

#storage mount
UUID=F2CE9013CE8FCE73 /mnt/data ntfs-3g auto,exec,rw 0 0

Now this drive automatically mounts and I have set the documents, pictures, music etc paths as default to this drive for both Windows and Linux to share.

Both installations are UEFI.

I only include this information because I wonder if windows has an issue until Linux mounts one of the drives. Seems unlikely, but I'm struggling to think of many reasons why it does this. I've done two clean installs of both Windows and Linux and the same issue persists. Sorry if I've left a jumble of information cluttered across this post, I was just trying to include everything that could be pertinent.



I once had a spinning circle in Win 10 because it couldn't connect to the internet, or so I believed. Maybe Windows has some issues with network hardware not starting correctly at cold boot?

There is no - at least no apparent - reason why this should happen.

While I am no longer dual-booting Windows (VBox Windows suffice) I have made exercise numerous times and I have yet to see your issue.

I only have one suggestion

  • boot to Manjaro
  • open a virtual terminal
  • run these commands
    sudo os-prober
    sudo grub-mkconfig -o /boot/grub/grub.cfg

Something which may enlighten us is your partition layout

sudo fdisk -l

Copy the text from the terminal - paste it - before pressing reply - select it again - then click the </> button in the post toolbar - nicely formatted and readable.

In addition to what @linux-aarhus mentioned, please post output of

inxi -Fxxxza --no-host

and show us your complete /etc/fstab file.

Thanks for the quick responses.

I don't see a /boot/efi partition on /dev/sda, how does it come? Is Windows really installed in UEFI mode or is the /boot/efi of /dev/nvme0n1 used for Windows boot as well (which won't be recommendable)?

Perhaps also

sudo blkid
findmnt -s
findmnt /boot/efi

The sda drive is just data, windows is installed on sdb, I believe it boots from the reserved partition (sdb3), but I'm not completely sure which each of the Windows install partitions are. It also has an EFI system on sdb2. Does it matter which drive is sda and which is sdb? I wouldn't have thought so, but am not that familiar with the whole thing.

I am not seeing anything "wrong" in the outputs you have posted so far, so this is a baffling case.

If I get time for it I might just have to re-install everything bit by bit with superfluous drives unplugged and check which stage breaks the Windows boot. I presume at the point where they were fresh installs with no other configuration they worked fine (although I didn't check specifically there).

Think that might take me a little while though.

can you check

I've been asking around about this in other Linux communities and there was a suspicion that secure boot might be a cause of the fault. I've checked and it's definitely disabled, but in looking for this I found that my BIOS was in extended CSM mode rather than UEFI, I've switched this back but still no joy. I wonder if I'll have to re-install now this is set to conventional UEFI boot.

I only think here the boot, esp flags should be set instead of msftdata.

Have you tried to physically disconnect your data drive /dev/sda? Maybe this disk caused problems.

Is Windows currently in hybrid sleep mode? That might be the issue. Try booting into Windows and doing a command line shutdown with

shutdown /s

To ensure it fully shuts off. Sometimes it doesn’t even if you disable hybrid sleep. My Windows will still go into hybrid sleep mode even if I turn hybrid sleep off, if the battery gets low, or there’s some issue with updating
