Woo-Hoo!!! BROTHERS AND SISTERS - I WAS ABLE TO INSTALL MX19b3 on my X1 carbon g4 this morning! I'm a genius! AMEN and PRAISE THE LORD
So ... here's the idiots guide to
MX-19b3 auto-install using entire disk
1) I burnt a new MX19b3 "base" ISO with LUM using my working MX-19 b2.1 on X1 g5
2) Took my
X1 g4 running MX-18.3-sept and changed in BIOS
Boot = [UEFI Only] and SRM = [DISABLED] ----- > thank you
Eadwine Rose !!!!!!!
3) Booted X1 g4 from MX-19b3 USB to live desktop
Now, important note for MX Devs
I don't know what use cases you guys test for the minstall GUI routine, but I went through these:
a) User is installing 19.3 on top of existing MX-18.3 (gpt partition table, but boot is on mbr as per my case) ->
FAIL with Error msg "Cannot format required partitions"
b) After failed step (a) User has re-formatted MX-18.3 partitions to Fat32 and Ext4 respectively - nothing fancy-shmancy like changing labels, mount points, etc. ->
FAIL Gpt shows (!) for ESP (missing software)
c) Lets assume User has a brand new NVMe M.2 (or wants to blow it away) - let's create
msdos partition table with Gparted (but no partitions) and format entire disk to Fat32 ->
FAIL
d) as above, let's create
gpt partitions table (but no partitions) and format entire disk to Ext4 ->
FAIL
e) let's create a new gpt partitions table and
leave the disk unformatted -
SUCCESS
SUMMARY
Your MX-19b3 auto-install GUI with UEFI will FAIL if:
1) You haven't set up your BIOS correctly, i.e. Secure Boot = [DISABLED] + UEFI Boot = [UEFI Only] + SMR = [DIsabled]
2) You're installing 19b3 over MX-18.3 which has had its boot set to MBR, or any other scenario except you blow away your entire disk and create a new GPT partition table (do NOT create any partitions and do NOT format the disk)
NEXT Test Cycle
Install MX19b3 from customised snapshot ISO (minstall.conf regression if/when Devs fix it) on:
a) same machine, over existing 19b3 (recovery)
b) different machine with whole disk blown away - as per Use case (e) above
