I tried to use LVM and wound up slaughtering my Windows & Linux installs. 
so while reinstalling Windows I used the disk manager to get rid of the LVM groups (couldnāt do it in Linux) and reinstalled both Windows and Linux. I learned a new trick though, using āmanual partitioningā in Debian, I was able to create new partitions on two hard drives instead of just one with the āGuided Partitioningā. I split my 500 gb SSD drive into seperate /, boot, swap and temp. I split my 3 TB HDD into 1/2 and one half went to /var, the other to /home.
Thankfully thatās over and all I gotta do is reinstall some programs on both Windows & Debian.
