Clonezilla can also update grub. Last time I upgraded system drive I had to do nothing.

HP Zbook 15" G7 working out of the box but not great detection reliability (might be an unfortunate specimen). Lenovo Thinkpad T580 much better although not working out of the box on LMDE

You can try with libreelec https://forum.libreelec.tv/thread/13250-testing-8-9-004-x86-acer-aspire-one/

I have LMDE on my T580.
