I have parted magic 2019_09_03. Works good. I made an ISO with 2019_11_04 and 2019_12_24. Both ISO's get as far as "starting mdadm" and then it will freeze. All 3 were made with rufus. The first one works. The other two will not work. Any ideas?
Are you plugging the USB directly into the motherboard's USB port and not using any type of sister extension hardware (i.e. front-mounted USB ports)? I will often use Parted Magic for its Secure Erase feature with SSD/SEDs and have had similar issues when not plugging the bootable USB directly into the motherboard via the rear of a PC.
I use 2019_09_03. No problem with this version. The 2 newer versions start but then freeze. I will just stay with 2019_09_03.
