I've installed a new 64GB SSD in my HP Compaq 2510p laptop. The SSD model is KingSpec KSD-ZF1.
This system is a single-boot machine running Ubuntu 14.04.2 LTS. There are no other operating systems installed on the computer.
Using the Ubuntu installer and allowing it to automatically partition my drive, then rebooting into the newly installed system results in the error: unknown filesystem. grub rescue>
message pictured here (not my picture, but this is the exact error given).
I can work around this error by using the "Something Else" option in the Ubuntu installer to manually partition my drive as follows:
- 512MB ext2 partition /boot
- ~60GB ext4 partition /
- 2GB swap area
I can then boot into Ubuntu without issue. I can run the OS all day with multiple shutdowns and reboots and there are no problems.
The issue comes the day after install - on the first boot of the day, there is no problem. On the second boot of the day, the system returns to the unknown filesystem
error mentioned above and must be repaired or reinstalled.
Since the error manifests itself on the second boot of each day, I suspect there may be something in /etc/cron.daily/
which is running on the first boot of the day and breaking GRUB, but I can't see anything obvious.
Has anyone ever come across anything like this before, and if so, what was the solution? I've searched around and can't find anything, hence asking this question.
For reference, on the laptop with its previous HDD, there were no problems at all installing and running Ubuntu. The problem seems to be with Ubuntu and this specific SSD.
Thank you in advance for any assistance - usually I'm the person helping people with their Ubuntu issues, but this one has me stumped! If anyone would like any more information, I'm happy to provide it.
sudo update-grub
when this is the case. This command is preformed by the system during certain updates; maybe this is the issue.
