The bootloader (grub in this case) will pass the boot parameters to the Linux kernel in a memory buffer called the kernel command line. The kernel command line, along with other console messages output during boot, should be in the system log, retrievable with the dmesg command.

A copy of the kernel command line is also in the file /proc/cmdline.

If your boot type is EFI, you can just type in cli after Linux booted:

efibootmgr -v

to see the current boot options and which partition/device you booted from.

Look at man efibootmgr if you are curious.
