I am a long time supporter of everything Purism. My family, friends and I have purchased 9 Purism laptops since 2019, a Librem 5 and a Librem key. Although I have a Librem 14 in the house, my favorite computer has been the Librem 15 v 4. Unfortunately, my second Librem 15 v 4 died (fried motherboard). I looked online for a Librem 15 v4, either new or used, and found nothing. Although I like the Librem 14, I wanted something newer with a larger screen. I ventured off the reservation and ultimately purchased a new Lenovo P16 gen 2. When I tried to install PureOS, it would not even load the iso on the usb stick. I tried my tails usb as well a usb with Ubuntu and Parrot OS and they all worked fined. When I contacted Lenovo for guidance I received this response:
Especially if bootable liveUSB is a few weeks old, download and build a new one today. Or try booting liveUSB with secure boot toggled off. You are booting with uefi only media configuration? Legacy and CSM and clicking to install MBR onto bootable media will prevent booting on newer Lenovo models. The old dual booting mode media, legacy and uefi won’t boot on newest Lenovo.
I am not sure what to do. I have installed PureOS on multiple computers including Dell and System 76, but my Lenovo won’t boot the iso. Any advice would be greatly appreciated. Thanks
