Hey everyone,

My desktop computer powering my stereo crashed randomly (that's weird for Ubuntu!), and on the next boot, I got this message from GRUB:


Error 18: Selected cylinder exceeds maximum supported by BIOS. Press ENTER to continue.

I pressed enter and it booted up just fine.

Is this the beginnings of a failing HDD? The drive is only 6 months old.

I didn't change any settings in GRUB, nor have I made any system changes.

Thanks for any help in advance!

Hello there.
If your Dual-Booting there's an article on the Linux Questions Wiki, that explains the problem and how to fix it.

I hope this helps.

i actually found that article earlier while searching around. the thing is though, i'm not dual booting. (well, not from a single hard drive anyway)

and the problem resolved itself. ubuntu booted successfully.

I just didn't know if this was something I should be worried about (hard drive). it hasn't happened since then, it was just a one-time thing, which is why I was getting curious... ;)

If it is a newer computer I do not know why you got error 18.

Herman has good explanation of error 18 - see if any of the special cases he discusses are like your setup.

Thanks for your help. It hasn't happened since then, and I'm going to assume this was the result of installing updated packages before the shut down. 8-)

if you using sata drive, try to replace sata cable, i was also facing this problem and i replaced sata cable with new one and it booted up normally.good luck.
