That is a fairly serious inconvenience : I hate the idea of having to use G= PT on my disk because I cannot use the Boot Easy manager (boot0cfg) under G= PT. Plus GPT inevitably leads to reckless partitioning. For disks under and upto 2 TB, MBR is supremely better. I did manage to get ZFS though, courtesy a spare slice available on my disk= . I installed FreeBSD using UFS on ada0s2 and migrated the setup to a ZFS tan= k under ada0s3 using the rsync strategy brilliantly detailed at : https://imil.net/blog/2016/04/28/Migrate-FreeBSD-root-on-UFS-to-ZFS/ But following the migration, I have made a serious error. I used Windows (a= da0s1) to delete ada0s2 : Windows has rearranged the MBR table to make ada0s3 -> ada0s2. I am now str= uggling to fix the MBR table. If you have any tips, that shall be wonderful Thanks for replying Manish Jain
