Dual Boot System Windows 10/LM19 no bootable device / Partition Recovery

#1 Post by itowill » 14 Oct 2018, 01:27

Hello So last week I was attempting to create a luks seure ubuntu bootable usb so i could put repairware and do some basic repair family.
apparently I should not have because I either typed command wrong or entered incorrect cmd because now my system is borked
I tried to run linux mint 19 grub rescue but there does not appear to be a grub menu. I tried using dell recovery but I cant seem to get past
bios and the epaOS where you can test parts of laptop. All the test pass including disk drive
I was able to boot into a live usb of ubuntu 18.04 but boot-repair did not work. I don't know if it maters that I have linux mint19 which i thought was ubuntu 18.04.1 compatible.
I downloaded test-disk and ran that where in the first menu displays

I am not sure of the files the say Disk/dev/loop0-7 mean but I know my Seagate is 500G so I select it
and presented with
the program detects Intel. I thought the system was UEFI and therefore GPT but perhaps someone can clear up what this means
so this is where I see Image
i can quicksearch or backup so I try quicksearch
then I see a Linux LVM option which does not find any partitions
but when click deepsearch this is screen I see https://imgur.com/a/xk5rSnY

this is where I am stuck. I did this same process yesterday but found the windows10 partition named OS but it
I still was not able to boot. Any help would be appreciated

The partition table looks OK. You may have to activate your LVM with
sudo pvdisplay
sudo vgdisplay
sudo vgchange -a y
sudo lvdisplay
