Ask HN: Is the installation syslog acceptable to start Ubuntu?

I'm preparing a new ThinkPad E14 for programming, and installed Ubuntu-Mate 22.04.02 in dual boot with Windows 10. Upon first dual boot bootup Ubuntu worked apparently ok, but I'm worried whether it is still installed correctly.

I examined the installation syslog a bit and searched for "error" messages (pasted below). Ubuntu Mate was supposed to be installed on the partition #5 of /dev/nvme0n1
