I'm using a 100mb partition for /boot on a clean install of Ubuntu 13.04. With only 2 kernels on it, it's already full. The biggest culprit seem to be both initrd (, images are around 32mb each (and a 22mb /boot/grub/unicode.pf2). I've used this same partition with an older install of 12.04 and I never had any problems with having multiple kernels. In fact, I had a whole ton of them.

While looking this stuff up, I've seen mention that it may be related to nVidia drivers. This would make sense because I encountered the "/boot has no space" error when trying to change my nVidia driver for the second time since the clean install.

Any thoughts on what I should do here? It would be a real pain in the butt if I could only keep 2 kernels at any one time.

Couldn't just make the /boot partition bigger? –  Braiam Aug 25 '13 at 0:02
I've got my Windows partition right up against the 100mb. I really don't want to have to reformat that, as it's a pain in the ass to get all the drivers up and running and get everything installed again. As far as I know, you can't move partitions with data in them either. –  Nick Aug 26 '13 at 12:17
In that case if you could add your fdisk -l would be awesome. –  Braiam Aug 26 '13 at 13:31
I got the error unable to seek on /dev/sda. My HDD is in RAID 0, so that may be related. –  Nick Aug 29 '13 at 17:44
I ended up reformatting and repartitioning the drives (except the Windows partition). I put the /boot partition after my existing Windows partition and sized it at 300mb. initrd is still the same size with this new install, so unfortunately the question asked here is not resolved, but my problem is. –  Nick Aug 29 '13 at 17:46
