Installation step

Tool could not be installed from sudo pip install because of below error

Error message

error: externally-managed-environment

How do I get the path to pass for --win parameter?

[Konfekt]

Use lsblk --fs to look for the NTFS disk and then mount to mount it to a folder, say \mnt. This folder can be passed to --win (but should also be autodetected once mounted).

as you can see there are 2 ntfs partition found, which one is the correct one ? @Konfekt

[Konfekt]

Probably neither as you seem to have Bitlocker enabled. Follow a guide to mount those partitions and add them after --win.

[HarshalRathore]

Well, the tool in that article did not work for me (and looks like for many others too) so I just had been left with one option according to my understanding which was to turn off the encryption on Windows sadly I wanted to keep Windows encrypted but as my research concluded that BitLocker encryption and Linux dual boot can not go hand in hand as BitLocker requires SECURE_BOOT turned on otherwise it will ask for recovery_key on every boot and without secure boot disabled we arch guys can not boot to Linux (jealousy towards those Ubuntu guys) but oh well the BitLocker encryption isn't that good it seems cause there have been successful bypassing of them as I found somewhere (PS I don't even have the real BitLocker actually no windows 10 home edition does :( ).

BTW thanks for your prompted reply my friend @Konfekt

I've never used BitLocker, Secure Boot is off, I am using Arch, but bt-dualboot --list-win-mounts shows this:

==================

a simple solution to this is go to your file manager in linux for example nautilus in my case and in '+ other locations' you'll see windows C file system click on it and it will ask for root password give it and viola the C drive was mounted the bt-dualboot --list-win-mounts now should show you the mounted partitions.

I had Windows 10 Home dual booted with arch linux maybe that's why i did not face this issue, glad it worked for you.
