#Can't boot into windows install on different drive

Hey guys,

Bit of a newbie here. Just looking for some help getting back into my windows install. I've got Grub installed with os-prober and have it enabled. os-prober doesn't seem to find the install though. I've manually added it with the following:

#!/bin/sh
exec tail -n +3 $0

This file provides an easy way to add custom menu entries. Simply type the

menu entries you want to add after this comment. Be careful not to change

the 'exec tail' line above.

menuentry "Windows 10" {
insmod ntfs
set root='(hd0,1)'
search --no-floppy --fs-uuid --set 6A7E505432C22828
chainloader +1
}

It now shows in grub but displays a "invalid EFI file path" error when selected.

The windows install does not appear in the BIOS either. I can confirm it is still showing with lsblk though

LMK if you need anything else to help!

Thanks

Thankyou @mighty parcel

I could have sworn I installed windows in UEFI but can't find a partition that's in Fat32. What's your take on this?

The Microsoft reserved partition wouldn't be it right?

#

I'm pretty sure it's not it

#

Use fdisk -l

Shouldn't there be an ESP there?

ebon helm
#

Yes there should

#

You probably installed grub in it

twilit coral
#

Hmm

#

What would be the next steps from here?

#

I'm fine with reinstalling windows tbh

#

but doing that will remove grub right? And I won't be able to get into linux

ebon helm
#

im pretty sure reinstalling windows on the partition you installed windows already will be fine

#

it could maybe modify grub to its own efi boot

#

but thats an easy fix and shouldnt be too big of a problem

I'm facing this problem
I installed an arch-based distro yesterday and everything went well
When I tried to back out to windows I had no option in dual boot

Enable os prober in grub
