How to solve this boot error message?

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Depending on if you wrote the kernel cmdline yourself I imagine this might happen using /dev/sdN style device paths? BIOS might change things up every now and then for fun, so using partition UUIDs would be a better way if so.
so can be bios dependent?..it's possible to change from /dev/sdn to UUIDs...how? Thanks
Basically just look for things like root=/dev/sda2 in the kernel command line. You can get it at runtime by running "cat /proc/cmdline" having /dev/sda etc in your fstab might also be a problem
You can change those to /dev/disk/by-uuid/XYZ ("ls -an" that directory to see the symlinks to your current drives)
Yes if you have multiple drives some buggy BIOS may not enumerate them in the same order every time. Most modern distros do UUIDs by default but when manually setting up a bootloader it is easy to succumb to such temptations to use the much simpler device paths as the UUIDs are a pain. If you're not sure how to change the kernel parameters most likely you're good on that front actually, its in your grub config as others have mentioned. I'll leave this comment around in case some poor soul who did it manually comes across the thread.
I hope by partition UUID you mean root=PARTUUID=, not root=UUID= because kernel can understand only PARTUUID.
Yes, forgot the exact details apologies
