I downloaded ubuntu 15.04 and burnt it onto a DVD. While booting from the disc, a warning message came up. I tried same disc on another laptop, and it worked. My one run ubuntu 14.10 well.
What do I do?

DISK 15.04 + Laptop other = works DISK 15.04 + Laptop yours = not working.
Is your laptop still have 14.04? can you run upgrade from it?
If not, any spare HDD to swap and test it? maybe HDD problem?
I usually just reinstall it...
Or if you can clone the system. 1) laptop other 's 15.04 works, right. 2) if you have a external hdd case, then a) put your HDD into this external hdd case b) assuming you have a DVD/USB 15.04 drive, boot laptop other with it. c) run gparted or you may need to sudo apt-get install gparted. d) run gparted, and then copy the "other laptop" OS partition into your external HDD. e) after copying/cloning, make sure in gparted, you modified the flag as "boot". f) put the external HDD's HDD back to your laptop and boot. g) if not booting, then boot from USB/DVD OS image again. -> google search boot-repair and follow instruction to install boot-repair. and choose recommended setting. it should fix it for you/
I hope one day ubuntu will put these tools in the release by default.
