During an update early this morning I noticed an error and sure enough. it's now impossible to reboot, even by using the "Boot from first hard disk" option offered by the Live CD/USB.
I saved the log and the error happened about here:
Auto-detection of a filesystem of /dev/sda8 failed, this is the / for the brtfs install.
(And Ooops!, I had the HD of my previous computer hooked up bia USB and that's what showed up as /dev/sdb)
This laptop has Win7 and two times 12.04 installed, the crash happened while in the version installed on brtfs, using the grub file on the external disk I can still access the ext4 install and that's where I'm in right now.
When I do sudo upgrade-grub the only partition recognised is the present but it does not result in a bootable system.
Without the external disk this grub menu is displayed white on black but any and all options are terminated with
When I try sudo update-grub from the Live CD I get an error stating /dev is not mounted.
Update:
In the mean time I have run
and I can do a regular boot into the ext4 version.
Update-grub does still not recognise the Win7 and btrfs OS's.
What I've so far googled suggests to run the Win7 CD for a repair but I feel this would not fix the problem with the brtfs install.
Any suggestions are welcome!
