[SOLVED] Dual Booting Help | Arch Linux Community | Page 1

I recently installed Arch Linux on a separate NVMe drive alongside Windows 11 in a UEFI system. After installing Arch and configuring GRUB, Windows stopped booting. I believe the Windows Boot Manager may have been corrupted.

Here’s what I’ve tried so far:
• Disabled Secure Boot and Fast Boot in BIOS
• Tried to run bootrec /fixboot, bootrec /scanos, etc. from the Windows recovery environment — but it either fails or bluescreens
• Re-enabled Secure Boot, but Windows still won’t load
• Arch Linux is booting fine via GRUB
• Both OSes are on separate NVMe drives

I’m looking for help to either restore the Windows bootloader or get GRUB to properly chainload Windows without breaking Arch. Any advice is appreciated.

@timber kite can you get into windows via boot manager?

#

Nah unfortuantly not. I am about just give up on it and move fully to linux. I am going to try and restore a backup I have

#

how did you install arch?

timber kite Apr 20, 2025, 4:30 AM

#

Through a USB. I partitioned it all myself

#

I did not use the script

distant glacier Apr 20, 2025, 4:30 AM

#

not archinstall?

timber kite Apr 20, 2025, 4:30 AM

#

No

distant glacier Apr 20, 2025, 4:31 AM

#

@timber kite from this? https://wiki.archlinux.org/title/Installation_guide

timber kite Apr 20, 2025, 4:31 AM

#

Yes

distant glacier Apr 20, 2025, 4:31 AM

#

no third party guide?

timber kite Apr 20, 2025, 4:32 AM

#

Nope

distant glacier Apr 20, 2025, 4:32 AM

#

timber kite Apr 20, 2025, 4:34 AM

#

I ran os-prober then updated grub

timber kite I ran os-prober then updated grub

timber kite Apr 20, 2025, 4:36 AM

#

distant glacier Apr 20, 2025, 4:37 AM

timber kite

now if you reboot take a photo of grub please

Okay. Give me like 5 minutes. I am sorry. I am installing a VM. If I can get this to work I may honestly just stay with Linux

#

I just need Windows for school

distant glacier Apr 20, 2025, 4:41 AM

#

timber kite I just need Windows for school

for what program(s)?

timber kite Apr 20, 2025, 4:42 AM

#

Really just lockdown browser but I know there may be an issue with the VM

#

Unfortunatly

distant glacier Apr 20, 2025, 4:44 AM

#

How longs the class? If 3 months or less you can freely download the Windows 11 Enterprise ISO and install it in a VM, it comes with a 90 (180?) day usage.

timber kite Apr 20, 2025, 4:44 AM

#

But can I use that with a lockdown browser? I have a key

distant glacier Apr 20, 2025, 4:44 AM

timber kite But can I use that with a lockdown browser? I have a key

yes

timber kite Apr 20, 2025, 4:45 AM

#

I didnt know you could use it in a VM

distant glacier Apr 20, 2025, 4:45 AM

#

I would ask whoever I'm taking the class for to provide a laptop that this could be run on

#

I'll get a second hand laptop with the os required and keep that ONLY for exams. After the exam, I'll close the thing and put it in a drawer until the next test.

#

Thats a pretty good idea honestly

distant glacier Apr 20, 2025, 4:46 AM

#

no dualboot needed

#

Perhaps it is a good idea to start a signature campaign asking the Respondus company to support Linux, as well as Virtual machine usage. Only supporting Windows and Mac and no Virtual machine by them, is basically locking countless of Linux using people out.

True

distant glacier Apr 20, 2025, 4:47 AM

#
