Can't repair Master Boot record with boot-repair tool. Xubuntu/Windows 7

[sic698]

Hi Guys,

I am unable to boot into any of my two operating systems, my 1st Partition is Xubuntu encrypted with Luks and my 2nd partition is windows 7 Pro.

When I run a live usb of ubuntu 18.04 LTS and then run boot-repair I get the following message

You may want to retry after decrypting your partitions. (https://help.ubuntu.com/community/En...ivateDirectory)
Do you want to continue?

I click on no and the operation is aborted, if I click yes and I continue the repair it doesn't repair my boot-records properly and I am unable to boot into either partition and no grub menu appears, all I get is a windows 7 repair window which never repairs the master boot record.

Thank you for having a look

To repair or even just run report, Boot-Repair needs to see your system.
So if encrypted you have to mount and decrypt your install.

I do not know LVM nor encryption.

For mounting encrypted see first few lines:

Setup ~ Desktop (Live) CD, Adding the tools to manage encrypted partitions

 Resizing  an encrypted partition must be performed from a live CD and support for  encryption and LVM are not included on the live CD. 
1. Boot the live (Desktop) CD and install lvm2 and cryptsetup. 
sudo apt-get update && sudo apt-get install lvm2 cryptsetup2. Load the cryptsetup module. 
sudo modprobe dm-crypt3. Decrypt your file system. 
sudo cryptsetup luksOpen /dev/sda5 crypt14. Get the live CD to recognize (activate) your LVM. 
sudo vgscan --mknodes
sudo vgchange -ay

"step 3"
sudo cryptsetup luksOpen /dev/sda5 crypt14. Get the live CD to recognize (activate) your LVM.

After step 3 I enter my password and I get the following message "Cannot use device /dev/sda5 which is in use (already mapped or mounted)."

im not sure how to proceed from here

sudo apt-get install lvm2   #This step may or may not be required.
sudo pvscan                 #Use this to verify your LVM partition(s) is/are detected.
sudo vgscan                 #Scans for LVM Volume Group(s)
sudo vgchange -ay           #Activates LVM Volume Group(s)
sudo lvscan                 #Scans for available Logical Volumes
sudo mount /dev/YourVolGroup00/YourLogVol00 /YourMountPoint
